Answer:
y=sqrt((x+a)/-2b))
F=(5/9)C+32
Can't read the rest
Step-by-step explanation:
-2by^2=x+a
y^2=(x+a)/-2b
y=sqrt((x+a)/-2b))
F-32=(5/9)C
F=(5/9)C+32 (The actual Fahrenheit-Celcius formula)

There is a lot to go over here. Unfortunately it looks like you got a lot incorrect. I'll focus on two problems. Hopefully these examples below will help correct the other mistakes.
---------------------------------------------------------
Problem 7)
We have the starting value be 20 and the ending value be 11. Subtract the values: (end)-(start) = 11 - 20 = -9. The negative indicates we have a drop or decrease.
We'll focus on the positive version of this number, so 9. Divide this value over the starting amount 20 to get 9/20 = 0.45 = 45%
So going from 20 miles to 11 miles is a decrease of 45%
Answer to problem 7 is: 45%
---------------------------------------------------------
Problem 13)
An increase of 300% means we added 3 times the original amount onto the original amount.
We take 300% of 25 to get 3*25 = 75
Which is then added onto 25 to get 25+75 = 100
Answer to problem 13 is: 100
The answer is B. 60 cubic inches
5 x 6 x 2 = 60
Answer:
1. $112.72
3. $112.50
4. $16.50
5. $7.26
6. $60.44
7. $8
8. $3.25
Step-by-step explanation:
1. Multiply 14.09 by 8.
3. Multiply 12.50 by 9.
4. Multiply 5.50 by 3.
5. Add 16.50, 9.75, and 10. Subtract 28.99 from that total.
6. Add all numbers listed in the problem.
7. Divide 56 by 7.
8. Divide 71.50 by 22.
It would be 120 because 4% of 125 is 5, so you subtract 5 from 125 to get 120. I am pretty sure that's how you do it
