Let x represent Holly's score on 7th math quiz.
We have been given that the mean of Holly's first six math quiz scores was 75%. This means that the average on 1st 6 math quizzes is 75.
To find the total scores on 1st 6 math quizzes, we will multiply 75 by 6 that is
.
We will use average formula to find test scores on 7th math quiz.


Let us solve for x.





Therefore, Molly's score on the 7th math quiz was 89.
Answer:
your answer is gonna be A!! <3
Step-by-step explanation:
1 Subtract 33 from both sides.
y-3=-2x
y−3=−2x
2 Divide both sides by -2−2.
-\frac{y-3}{2}=x
−
2
y−3
=x
3 Switch sides.
x=-\frac{y-3}{2}
x=−
2
y−3
Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.
Answer:
One step Equations:
1. x=4
2. x=18
3. x=3
4. ×=50
Two Step Equations:
1. x= 7
2. x= -4
3. x= 24
Variations on Both Sides:
(I'm not sure if these are right but the answers above are for sure correct)
1. x= 4.5
2. x= -2
The answer is D because the shaded area must go to the origin and it must have a non-dashed line because having 5 sundaes and 10 cones is possible.
