Read the excerpt from an interview with Florence Griffith-Joyner.
WILL: I know that you dropped out of college in 1979 to help support your family. It seems like family must be very important to you.
FLORENCE GRIFFITH-JOYNER: Yes. Family is first in my life. It was a very difficult decision for me to drop out of college at that time. Growing up in poverty, I didn't have the financial support that I would have needed to go to college. I wasn't offered an athletic scholarship. I wasn't offered an academic scholarship. I thought, "How am I going to stay in school?" So I enrolled in school, and I thought, "I really want to run, but I know I have to concentrate on my academics as well." I tried a year of college, and I thought, "I can't continue because I have no financial support." I had to take the bus two hours to school, two hours back. The need was greater than what I could afford.
What is the purpose of the interviewer’s question?
A. to share Florence Griffith-Joyner's training techniques
B. to share Florence Griffith-Joyner's family recipes
C. to share Florence Griffith-Joyner's commitment to family
D. to share Florence Griffith-Joyner's favorite coach

Give an example of an equation with an infinite number of solutions. Then make one change to the equation so that it has no solution.
An example of an equation with infinitely many solutions: 4x + 3 = 4x +_____
The equation with one change and no solutions: 4x + 3 = ______
Answer:
I)3 II)4x
Step-by-step explanation:
for the infinite number of solutions you need to make both equations on both sides equal
but in the one for no solution you need to make one number is equal to another number, which is wrong in Math, that's why there's no solution in it

Answer:
There will be an estimated amount of 1125 faulty souvenir tokens.
Step-by-step explanation:
Hi!
So, let's do this problem out.
So we for every 400 tokens, 3 are faulty
Let's write that in a ratio
3:400
Ok, great!
So, now we know that:
3:400 = x:150,000
We can set up a percent proportion
[tex]\frac{3}{400} =\frac{x}{150,000}[/tex]
To find x, we do:
[tex]x=\frac{3*150,000}{400}[/tex]
[tex]x=\frac{450,000}{400}[/tex]
[tex]x=\frac{4,500}{4}[/tex]
[tex]x=1125[/tex]
There will be an estimated amount of 1125 faulty souvenir tokens.

Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.
a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.
Answer:
Equation: y=(-1/20)x+12.
Slope: -1/20
Y-intercept: (0, 12)
Step-by-step explanation:
Let x=the number of gallons of gas in Christopher's car.
If we start with 12 gallons, we have the equation: y=(-1/20)x+12.
This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).
