Astudent improved his score from 20 points on his first attempt to 22 points on his second attempt. by what percent did his score improve?

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

the answer is 11.2 (i know i’m late)

the answer is about 24 dollars
