4. Chris and Keith went to a carnival. Chris started with 80 tickets and spent x tickets at the carnival, Keith started with 140 tickets and spent 2x tickets at the carnival. At the end of the night, they had the same number of tickets left over. How many tickets did Chris spend at the carnival?
Answers
Answer: x=20
Step-by-step explanation:
3x+80=140
3x=60
x=20
Answer: Chris spent 60 tickets at the carnival.
Step-by-step explanation:
At the end of the night, both Chris and Keith had the same amount of tickets, so:
80 - x = 140 - 2x
Now, solve the equation. Start by bringing the -2x to the left side.
80 - x + 2x = 140
Bring the 80 to the right side so the variables are isolated.
-x + 2x = 60
Add like terms.
x = 60
Check the work.
Chris had 80, spent 60, so had 20 left. --> 80 - 60 = 20
Keith had 140, spent 120 (60 *2), so also had 20 left. --> 140 - 120 = 20
So, Chris spent 60 tickets at the carnival.

Hope I get this right and not wrong
Answer:
6t+6y+11
Step-by-step explanation:
Like terms basically mean that if it has the same variable, you can add or subtract them. So if we have -2t+8t, we get 6t in total, we also have 4+7=11, and since there is no other y variable, we keep it as is. Therefore the answer is 6t+6y+11.

A line is represented by the equation y=3/8x+1. what is the slope of the line?
Answers
Answer:
3/8
Step-by-step explanation:
the equation is in slope intercept from (y= mx +b) mx= slope b= y intercept
Answer: 3/8
Step-by-step explanation:
In slope-intercept format (y = mx+b), your m will be your slope so in this case you have y = 3/8(m)x + 1(y-intercept)
Data was collected on the amount of time that a random sample of 8 students spent studying for a test and the grades they earned on the test. A scatter plot and line of fit were created for the data.
Determine the equation of the line of fit.
y = 15x + 60
y = 15x + 30
y = 30x + 60
y = 30x + 30
Answers
Answer:
Y=30x + 60
Step-by-step explanation:
Because most of the students time of doing a test is 90 minutes and 15x isn't the answer so, anything with 15x is not the answer.
To determine the equation of the line of fit, we need more information about the data and the line that was created. The equation of a line is typically represented as:
y = mx + b
Where:
y is the dependent variable (in this case, the grades earned on the test),
x is the independent variable (in this case, the amount of time spent studying),
m is the slope of the line, and
b is the y-intercept of the line.
Without additional information or the actual data points, it is not possible to determine the exact equation of the line of fit. The provided options (y = 15x + 60, y = 15x + 30, y = 30x + 60, y = 30x + 30) represent different possible equations based on the given information. However, without further context or calculation, it is not possible to determine which equation is correct.

the distance between the football stadium and train station on a map is 2.5 inches. the scale of the map is 1 in. : 1/2 mlie. What is the actual distance between the football stadium and train station?
Answers
The scale of the map is 1 inch : 1/2 mile, which means that one inch on the map represents a distance of 1/2 mile in real life.
To find the actual distance between the football stadium and train station, you need to multiply the distance on the map by the scale factor.
The distance on the map is 2.5 inches, so the actual distance is 2.5 inches * 1/2 mile/inch = 1.25 miles. This is the distance between the football stadium and train station.
Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

(solve, show work) Jennifer earns $1,920 in interest after making a deposit 6 months ago at a rate of 12.5%. What was the initial deposit 6 months ago? PLS answer this seriously its really important tysm!
Answers
Answer:
P = $1807.058
Step-by-step explanation:
Given
A=$1, 920
R=12.5% =12.5/100
T= 6month = 6/12 .... to change to year
Required
p=?
Solution
A= I + P ......... I= PRT
A = PRT + P
A= P(RT+1)
$1920 = P( 12.5/100 ( 6/12) + 1 )
$1920= P(1.0625)
P = $ 1920 / 1.0625
P = $1807.058
We can use the simple interest formula to solve this problem. The formula is:
I = P*r*t
where I is the interest earned, P is the principal (initial deposit), r is the annual interest rate, and t is the time in years.
First, we need to convert the annual interest rate of 12.5% to a monthly rate. We can do this by dividing the annual rate by 12 (the number of months in a year):
r = 12.5%/12 = 0.01041667
Next, we need to convert the time of 6 months to a fraction of a year. We can do this by dividing 6 by 12:
t = 6/12 = 0.5
Now we can plug in the given values and solve for P:
I = P*r*t
$1,920 = P*0.01041667*0.5
$1,920 = P*0.00520833
P = $1,920/0.00520833
P = $368,640
Therefore, the initial deposit 6 months ago was $368,640.
