Answer:
12
Step-by-step explanation:
do 4x+3x+6=90 combine like terms 7x+6=90 subtract 6 from both sides 7x=84
divide both sides by 7 x=12
So, solve this for x. Combine like terms. The problem should now look like: 7x+6=90. Now, we need to isolate the x. Subtract 6 from 6, and subtract 6 from 90. This is because we must move the 6 to the other side of the problem to find x. Whatever we do on one side of the problem, we must do on the other. The problem should now look like 7x=84. Now, isolate the variable by dividing 7x by 7. Again, you must do the same thing to both sides of the problem. So, you must also divide 84 by 7.
The answer is x=12.

2.4*2.4= 5.76
4.0*5.76= 23.04
Answer: The area of the given shape is 9.734 meter square
Step-by-step explanation:
The given shape is a square with 4 sides of equal dimensions "a",
Area of Square = Square of its side "a"
Here, a = Hypotenuse of the inner triangle
Step 1: Get the hypotenuse value of the inner right triangle as the base and height dimensions of the right triangle is given.
Step 2: By using Pythagoras theorem,
Square of the base + Square of the height = square of the Hypotenuse
(2.4)^2 + (2.0)^2 = 9.76
Therefore the value of the hypotenuse = 3.12m
The area of the square = 9.734 meter square.

The scatter plot shows the systolic blood pressure of people of several different ages. The equation represents the linear model for this data.
y = x + 95
According to the model, how much does the systolic blood pressure increase for each year of age?
1 mm Hg per year
5 mm Hg per year
15 mm Hg per year
95 mm Hg per year
110 mm Hg per year
A graph measuring systolic blood pressure in relation to age. A line indicates that blood pressure increases as age increases
Answers
We can see it is in the format y = mx + b,
where m represents the slope, or the rate of increase.
Since x is alone, it is assumed to be “1x”, with 1 being m, the slope.
Therefore the systolic blood pressure increases by 1 mm Hg per year.
Another way to solve this if you didn’t have the equation:
If we find two easy to pinpoint plots such as:
(0,95) (15,110)
The equation for slope is
x - x / y - y
15-0 / 110-95
= 15/15

Tom is saving money to buy a game. So far he has saved $18, which is two-thirds of the total cost of the game. How much does the game cost?
Answers
To determine the total cost of the game, we can set up an equation based on the given information.
Let's assume the total cost of the game is represented by the variable "x."
According to the problem, Tom has saved $18, which is two-thirds of the total cost. We can express this as the equation:
(2/3) * x = $18
To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:
(3/2) * (2/3) * x = (3/2) * $18
x = $27
Therefore, the game costs $27.

The number of cookies that were made at a bakery for each of seven days is shown:
108, 96, 96, 84, 108, 240, and 84
The best measure of center for this data set is the-
A: median because all of the values are close to one another in value
B: mean because all of the values are close to one another in value
C: median because 240 is much higher than the other numbers in the data set
D: mean because 240 is much higher than the other numbers in the data set
Answers
The data set is as follows: 108, 96, 96, 84, 108, 240, and 84.
The median represents the middle value when the data set is arranged in ascending or descending order. In this case, when we arrange the data in ascending order, we have: 84, 84, 96, 96, 108, 108, 240. The middle value is 96, which is the fourth value in the sorted data set.
The mean is calculated by summing up all the values and dividing by the total number of values. In this case, the sum of the values is 756 (108 + 96 + 96 + 84 + 108 + 240 + 84), and there are seven values. Therefore, the mean is 756/7 = 108.
Comparing the options:
A: median because all of the values are close to one another in value - This is not accurate as the values vary, and the median is not necessarily the best measure of center based on the values being close to one another.
B: mean because all of the values are close to one another in value - This is not accurate as the values are not all close to one another, and the mean is not necessarily the best measure of center based on the values being close to one another.
C: median because 240 is much higher than the other numbers in the data set - This is not accurate as the presence of a single high value does not automatically make the median the best measure of center.
D: mean because 240 is much higher than the other numbers in the data set - This is the most accurate option. The mean takes into account the magnitude of each value and is influenced by extreme values. The value 240 has a significant impact on the mean, making it a better measure of center in this case.
Therefore, the best measure of center for this data set is D: mean because 240 is much higher than the other numbers in the data set.

Answer:
The number of monthly calls for which Plan 1 is more economical than Plan 2 is 200 calls If more than 200 calls are made, the plan 1 charge will be more than plan 2. Let the number of charges per month be x If plan 2 charges $16 per month plus $0.04 per call, this is expressed as 0.04x + 16 Price that pan 1 charges = $24 If Plan 1 is more economical than Plan 2, this is expressed as:0.04x + 16 > 24 Subtract 16 from both sides:0.04x + 16 - 16 > 24 - 16 0.04x > 8 x = 6/0.04 x = 200 This shows that if more than 200 calls are made, the plan 1 charge will be more than plan 2.

The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.
Answers
- Range: The range is the difference between the maximum and minimum values in a data set.
- IQR: The IQR is the range of the middle 50% of the data values. It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1).
In the given box plot:
- The lines outside the box represent the minimum and maximum values.
- The box represents the middle 50% of the data, with the line inside the box representing the median (or second quartile, Q2).
- The distance between the lower whisker and the bottom edge of the box represents the first quartile (Q1), and the distance between the upper whisker and the top edge of the box represents the third quartile (Q3).
Based on the information provided in the box plot, we can determine the range and IQR as follows:
- The minimum value is represented by the lower whisker, which ends at 15.
- The maximum value is represented by the upper whisker, which ends at 52.
- Q1 is located at the bottom edge of the box, which is 26.
- Q3 is located at the top edge of the box, which is 49.
Now we can calculate the range and IQR:
- Range: maximum value - minimum value = 52 - 15 = 37
- IQR: Q3 - Q1 = 49 - 26 = 23
Therefore, the correct statement is:
The range is 37, and the IQR is 23.
Answer:
The range is 37, and the IQR is 23.
Step-by-step explanation:
A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.
Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.From the given information, the five-number summary of the Jumping Jacks box plot is:
Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52RangeThe range is the difference between the maximum and minimum values. Therefore, the range for the data is:
\(\sf Range = 52 - 15 = \boxed{\sf 37}\)
Interquartile range (IQR)The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:
\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)
SummaryThe range is 37, and the IQR is 23.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Answers
Source ? Just trust me bro
60 percent of the jerseys are medium-sized jerseys.
what is percent?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
total jersey= 25
15 are medium-sized jerseys.
Now, let the percent be x
So,
x% of 25= 15
x/100(25)= 15
x/4= 15
x= 60%
Hence, 60 percent of the jerseys are medium-sized jerseys.
