-5n-8-56n=-8 i did multiply the parenthesis
we will combine like terms
-5n-56n=-8+8
-61n=0
n=0
Answer:
n=0
Step-by-step explanation:
Remember your terms, whether it be PEMDAS / GEMS. I am going off GEMS so:
Grouping which are the parentheses; -8(1+7n) = -8-56n.
Next, combine your like terms:
-5n-8-56n=-8
-61n-8=-8
Add 8 to both sides, remember what you do to one side, you do to both sides.
-61n=0
Divide both sides by -61, your answer is 0.

Answer:
The number of students enrolled at a college is 18,000 and grows 3% each year. Complete parts (a) through (e).
a) The initial amount a is 18,000.
b) The percent rate of change is 3%, so the growth factor b is 1 + 0.03 = 1.03.
c) To find the number of students enrolled after one year, you calculate 18,000 · 1.03.
d) Complete the equation y = 18000 · 1.03^2 to find the number of students enrolled after x years.
e) Use your equation to predict the number of students enrolled after 21 years.

Daily driving time (hours)
Which of the following is the closest estimate to the percentile for the driver with a daily driving time of 6
hours?
Answer: 8/14
Step-by-step explanation: make 8/14 into a percent and you have the answer for khan
The closest estimate to the percentile for the driver with a daily driving time of 6 hours is 57th if the dot plot shows the number of hours of daily driving time for 14 school bus drivers.
What is a percentile?A percentile is a score that relates one rating to the scores of the rest of the group. It represents the proportion of scores that a given score surpassed.
We have:
Total number of observations N = 14
Index for 6 = 8
Percentile for the observation:
P = (R/N)×100
P = (8/14)×100
P = 0.571×100
P = 57.14 or
P = 57th percentile
Thus, the closest estimate to the percentile for the driver with a daily driving time of 6 hours is 57th if the dot plot shows the number of hours of daily driving time for 14 school bus drivers.

5. Andre makes green paint by mixing 5 cups of yellow paint with 2 cups of blue paint.
To make the same shade of green, how much yellow paint does Andre need if he uses 8 cups of blue paint?
How much blue paint does Andre need if he uses 15 cups of yellow paint?
Plot these pairs of measurements as points on the graph.
Answer:
for part 1, the answer is (8, 20), and part 2 is (6, 15)
Step-by-step explanation:
hope this helps you out! :)
Andre needs 6 cups of blue paint to make the same shade of green using 15 cups of yellow paint.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To make green paint, Andre uses a ratio of 5 cups yellow paint to 2 cups blue paint.
To make the same shade of green using 8 cups of blue paint, we need to use the same ratio of yellow paint to blue paint as before.
So we can set up a proportion:
5/2 = x/8
where x is the amount of yellow paint Andre needs.
Solving for x, we get:
x = (5/2) x 8 = 20 cups
Andre needs 20 cups of yellow paint to make the same shade of green using 8 cups of blue paint.
To make the same shade of green using 15 cups of yellow paint, we can set up another proportion:
5/2 = 15/y
where y is the amount of blue paint Andre needs.
Solving for y, we get:
y = (2/5) x 15 = 6 cups
Therefore,
Andre needs 6 cups of blue paint to make the same shade of green using 15 cups of yellow paint.

Last night, Julie’s pet hamster Zoe kept Julie awake for at least an hour running on her exercise wheel and scratching at the corner of her cage. Zoe ran on the wheel at least twice as long as she scratched at the quarters of her cage, and she spent more than 1/4 hour rubbing on her wheel.
Which System of inequalities represents the time Zoe kept Julie awake last night if X is the number of hours that she spent running on her wheel and y is the number of hours spent scratching at her cage?
Answer:
[tex]x+y\geq 1[/tex]
[tex]x\geq 2y[/tex]
[tex]x\geq \frac{1}{4}[/tex]
Step-by-step explanation:
In order to solve this problem, we just need to translate mathematically what the problem is talking about. First, we know that:
x=# of hours she spent running on her wheel.
y = # of hourse she spent scratching at her cage.
So, let's split the problem into little chunks of information that will be easier to translate. This is split it into sentences.
So first:
Julie's pet hamster Zoe kept Julie awake for at least an hour running on her exercise wheel and scratching at the corner of her cage. This means that the least amount of time Julie was awake as an hour in total, so this can be written as an inequality like this:
time spent running + time spent scratching is less than or equal to 1 hour
[tex]x+y\geq 1[/tex]
next,
Zoe ran on the wheel at least twice as long as she scratched at the quarters of her cage.
This is:
[tex]x\geq 2y[/tex]
and finally, she spent more than 1/4 of an hour running on her wheel.
[tex]x\geq \frac{1}{4}[/tex]
so the system of inequalities is the following:
[tex]x+y\geq 1[/tex]
[tex]x\geq 2y[/tex]
[tex]x\geq \frac{1}{4}[/tex]

Sonya made a graph showing the first ten minutes of her drive to the movies.
A graph with time on the x-axis and speed on the y-axis. The graph increases, increases rapidly, and then remains constant.
Which description is the best interpretation of the graph?
Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
Sonya backed out of her driveway at a constant speed and then accelerated until she reached the street where the movie was playing. She stopped the car.
Sonya drove down her driveway at a constant speed until she reached the street. She turned and drove down the street at a constant speed. Her car went slower as she drove up a hill. At the top of the hill she drove into the parking lot of the movie theater.
Sonya accelerated as she drove down her driveway. She accelerated on the street on her way to the highway entrance. She waited for a red light, then accelerated onto the highway.
Answer:

1. If Z2 measures 120°, what is the measure of Z1? Explain how you found the measure of 21.
Answer:
60
Step-by-step explanation:
Angles 1 and 2 are supplementary, which means that their sum is 180 degrees.
180 - 120 = 60
Angle 1 is 60 degrees
If Z2 measures 120°. We can see that Angles 1 and Angles 2 are supplementary. Therefore, Angle 1 is 60 degrees.
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles.
If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.
Those two-two angles are two pairs of supplementary angles.
That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
If Z2 measures 120°
We can see that Angles 1 and Angles 2 are supplementary, which means that their sum is 180 degrees.
Angles 1 + Angles 2 = 180
Angles 1= 180 - 120
Angles 1 = 60
Therefore, Angle 1 is 60 degrees.

Charles Joyner earns a biweekly wage of $2,470. During the most recent week, he worked 45 hours. Regular Wage Rate = $ Overtime Wage Rate = $
Answer:
wage rate = $27.44
Overtime Wage Rate = $68.6
Step-by-step explanation:
given data
biweekly wage = $2,470
work = 45 hours
solution
we know that here No of Days in a Biwek is 14 day and No of Hour Worked in one week is 45 Hour
so that we can say No of Hour Worked 2 week = 90 hours
so
we get here first regular wage rate that is
wage rate = Total biweekly wages ÷ No. of Hour worked in a biweek
wage rate = [tex]\frac{2470}{90}[/tex]
wage rate = $27.44
and
Overtime Wage Rate will be
as overtime hour = 45 hour - 40 hour = 5 hours
Overtime Wage Rate = regular rate × overtime hour ÷ 2
Overtime Wage Rate = 27.44 × 5 ÷ 2
Overtime Wage Rate = $68.6
