Which expression is equivalent to 4/5x + 1 1/5?
A. 1/5 (4x + 1)
B. 2/5 (2x + 3)
C. 4/5 (x + 2)
D. 5/4 (x + 1)
I'd love it if you gave me an explanation for this.
Answers
Answer:
The answer would be B!
Step-by-step explanation:
To find which expression is equivalent, do the distributive property.
A. 1/5 * 4x = 4/5x
1/5 * 1/1 = 1/5
4/5x + 1/5 <--- This is wrong!
B. 2/5 * 2x = 4/5x
2/5 * 3/1 = 6/5 = 1 1/5
4/5x + 1 1/5 <--- This is correct!
C. 4/5 * x = 4/5x
4/5 * 2/1 = 8/5
4/5x + 8/5 <--- This is wrong!
D. 5/4*x = 5/4x
5/4 * 1/1 = 5/4
5/4x + 5/4 <--- This is wrong!
Therefore, the answer is B! Hope this helps!

Does the graph represent a function?
Answers
Hey there!
No, the graph is not a function because it has two of the same inputs, (7, -6) and (7, -7).
It also can't be a linear function because the graphs are not pointed to form a straight line.

A triangle has sides with lengths 5, 6, and 7. Is the triangle right, acute, or obtuse? Question 2 options: A) Obtuse B) Right C) Can't be determined D) Acute
Answers
Answer:
D: Acute triangle
Step-by-step explanation:
First check whether this could be a right triangle. Using the Pythagorean Theorem, we get:
5^2 + 6^2 = ? = 7^2 This equation is not true, and therefore the triangle is not a right triangle.
The side lengths 5, 6 and 7 are very close to one another, and so the triangle must have essentially similar interior angles, which means that all three angles are acute. Answer D is correct: This is an acute triangle.
Answer: D) Acute

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

Brainlist for positive attitude and correct answer :D
Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Hi there! :)
We can begin by writing algebraic equations to express both of the situations. Use the format y = mx + b (slope-intercept form) to display the cost of each:
Recall that:
m - rate of change of cost (ex: amount per guest)
b - initial charge (ex: cost to rent the room)
Write the equations given the information in the table:
Bowling-Fun: y = 4x + 250
Arcade-A-Rama: y = 9x + 120
Part A.
Solve for the number of guests that would result in a same price from both locations by setting the two equations equal to each other:
4x + 250 = 9x + 120
Begin solving by subtracting 4x from both sides:
250 = 5x + 120
Subtract 120 from both sides to further isolate x:
130 = 5x
Divide both sides by 5:
x = 26 guests.
Part B.
Find the less expensive choice by plugging in the amount of guests (80) for x:
Bowling-Fun: y = 4(80) + 250 = $570
Arcade-A-Rama: y = 9(80) + 120 = $840.
$570 < $840
Therefore, Bowling-Fun is the cheapest option for 80 guests.
Part C.
The slope represents the rate of change. In this instance, this is the amount per guest, which is $4 dollars.
Part D.
The y-intercept represents the initial, one-time amount. This is the amount paid for the room, which is $120.
Elsa is taking physical fitness tests in her strength training class. Each day, her results are compared to her results from previous days. The first day she completes a test is considered the baseline, and is represented by 0. For instance, on the first day she did the flexibility test, her result was calculated as 0. On the second day, in comparison to her first day's result, she was able to reach 1 and 1/16 inches less than the first day, which was recorded as -1 and 1/16. Then, on the third day, Elsa recorded a result of -5/8.

Step-by-step explanation:
60/4 which is the chance it gets out of being drawn
Using the concept of probability, the reasonable prediction for the number of times a purple marble will be drawn is 12 times (option A).
What is a reasonable prediction for the number of times a purple marble will be drawn?To predict the number of times a purple marble will be drawn, we can use the concept of probability. The probability of drawing a purple marble in a single draw is the number of purple marbles (4) divided by the total number of marbles (5 + 6 + 3 + 2 + 4 = 20).
Probability of drawing a purple marble = 4 / 20 = 1/5
Since the student makes a total of 60 draws and each draw is independent (the marble is returned to the bag after each draw), we can use the concept of expected value to predict the number of times a purple marble will be drawn.
Expected value = Total number of draws × Probability of drawing a purple marble
Expected number of times a purple marble will be drawn = 60 × (1/5) = 12

Answers
Answer:
133°
Step-by-step explanation:
The 2 necessary statements we can derive from the diagram are :
⇒ ∠4 = 180° - 47° (Statement 1) (Adjacent angles)
⇒ ∠4 = ∠5 (Statement 2) (Alternate Interior Angles)
Solving :
Substitute Statement 2 in Statement 1 :
⇒ ∠5 = 180° - 47°
⇒ ∠5 = 133°
Answer: 133 degrees
Step-by-step explanation:
The figure shown here is parallel lines with a transversal.
A transversal is a line that passes through 2 lines that are parallel to each other. When a transversal crosses the paralel lines, the angles seen will essentially be duplicates of each other. Let's take angle 2, for instance. We know its measure is 47 degrees. Now look at angle 6. It is the same as angle 2 because the same line is passing through the same type of line, but they're just in different places.
Therefore angle 6 is 47 degrees. Mark it on the angle (see screenshot).
Ok, now that we know angle 6, we have enough information to solve for angle 5 without having to find the measures of all the other angles. As you can see, angle 6 is right next to angle 5. this means that their angle measures must add up to 180, as they form a straight line. *when 2 angle measures add up to 180, or form a straight line, they are supplementary angles
Anyhow, we know that 47+ x= 180.
x+47= 180
x= 180-47
x= 133
Checks:
If angle 5 is 133 degrees, angle 5+ angle 6 has to equal 180.
133+47= 180.
This is how I know angle 5= 133. Also another method to double check is to "eyeball" angle 5 and see if it is obtuse or acute. It is obtuse, so 133 degrees sounds reasonable.

it is c because For outcomes to be equally likely they need to have probabilities that are relatively close to each other.

D:
x=0.1,0.3,25,100
y=200,40,0.8,0.2
Answers
Answer:
A, C
Step-by-step explanation:
If it is inversely proportional then y = k/x
Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)
A.
6 = k/1 (k=6)
3 = k/2 (k=6)
2 = k/3 (k=6)
1.5 = k/4 (k=6)
Yes! It's the same everywhere so this is correct!
B.
7.5 = k/2 (k=15)
5 = k/3 (k=15)
3 = k/5 (k=15)
2 = k/7 (k=14)
For the last one k is not the same so nope. It is wrong.
C.
24 = k/1 (k=24)
8 = k/3 (k=24)
k = 6×4 = 24
k = 24×1 = 24
This is correct too.
D.
k = 0.1×200 = 20
k = 0.3×40 = 12
k = 0.8 × 25 = 20
We can already see that k is not the same everywhere.
Only A and C, x and y are inversely proportional for all of the values

Jackson works as a veterinary technician and earns $12.20 per hour. Jackson normally works 40 hours a week. And a normal week, what is his total pay before taxes and other deductions
Answers
Answer:
p = 12.20h
30.5 hours
Step-by-step explanation:
Jackson works as a veterinary technician and earns per hour = $12.2
He works in a normal week = 40 hours
Let hours = h and weekly pay = p
p = 12.20h
p = $12.20 × 40
= $488.00
Last week Jackson was ill and missed some work.
His total pay before deduction was $372.10
To find the hours he work the equation will be p = 12.20h
372.10 = 12.20h
372.10/12.20 = h
h= 30.5
