Answer:
Options: A, B, and C correctly solve for x.
Step-by-step explanation:
A).
= 
Multiplying both sides by 2 gives;
5x = 15
x = 15 ÷ 5 = 3
∴ This option correctly solve for x.
B).
x +
= 7
x = 7 -
= 
∴ This option correctly solve for x.
C).
x + 3 = 
x = 
But the option give x as 5/6 hence this option does not correctly solve for x.
D).
5x = 11/2
x = 11/2 ÷ 5 = 11/2 × 1/5 = 11/10
But the option gives x as 10/11 so it does not correctly solve for x.
Answer: 14 7/8
Step-by-step
I put the 4 1/4 into an improper fraction then did keep change flip
If you divide 6 by 8= 0.75, which is equivalent to 75%. So Amber made 75% of her free throws.
80% of what is 56
0.80x = 56
x = 56 / 0.80
x = 70....so he attempted 70 free throws
