Answer:
89
Step-by-step explanation:
Given that Wendy took 2 tests and scored, 77 and 80 respectively, let x represent the grade of Wendy's third test.
To get an average grade of 82, let's generate an equation to find x (Wendy's grade on her third test).
Average grade = sum of all 3 grades all over 3
Multiply 3 by both sides
Subtract 157 from each side of the equation
Wendy must score 89 on her third test to have an average of 82.

Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
Knowing this, and having the equations provided in the exercise, you can identify the slope and the y-intercept of each line.
- In Equation 1:
- In Equation 2:
- In Equation 3:
Answer:
18
Step-by-step explanation:
5 scores so far + next quiz =6 scores
6 times 16=96
She has to get a quiz score sum of 96 to get an average of 16
