Joey wants to earn an A on his report card. So far he has taken 3 exams and has one more to go. On the first three exams, Joey scored 88%, 92%, and 84%. What does Joey
need to score on the last test to have an average of 90% for the 9 weeks?

96%

Step-by-step explanation:

To have an average of 90 for 4 exams, you know that the sum of the scores on all 4 exams would be 90 * 4 = 360. The sum of the first three scores is 88 + 92 + 84 = 264.

The last thing you have to do is 360 - 264 = 96 because then you know the score he has to get is 96 for an average of 90 on all four exams.

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

answer is : muchas/tipicas

have a nice day!
