Answer:
The next score he needs to have an overall average of 79 is 89.
Step-by-step explanation:
Gary earned an average score of 77 on his 5 quizzes . The number of score he needs to have an average of 79 can be calculated below.
average score = 77
number of quizzes = 5
sum of Garry score = a
a/5 = 77
cross multiply
a = 77 × 5
a = 385
let
the next score he needs be b to score an average of 79
average = 79
number of quizzes = 6
385 + b/6 = 79
cross multiply
385 + b = 474
b = 474 - 385
b = 89
The next score he needs to have an overall average of 79 is 89.

The <em><u>correct answers</u></em> are:
substitution property; subtraction property of equality; division property of equality; and reflexive property.
Explanation:
The difference between the given statement and the first statement is that 11x is replaced with 88. This is because we are told that x=8; 11(8) = 88. Substitution has been used here.
The difference between the first step and the second step is that 88 is no longer on the left hand side and the right hand side is -89. This is because to cancel 88, it has been subtracted from each side of the equation. This is the subtraction property of equality.
The difference between the second step and the third step is that -6 is no longer on the left side and the right hand side is 89/6. This is because to cancel -6 both sides were divided by -6. This is the division property of equality.
The difference between the third step and the last step is that the 89/6 and y have been flipped around the equals sign. This is the reflexive property.
