Step-by-step explanation:
79 is 4 below 83 so her next grade needs to be 4 above in order to get an average of 83. The answer is 87.
m= 4+ 2c is true if m is claires mom and c is claire
we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.

</h3><h3>What is the scale factor from M to S?</h3>
Suppose we have a figure S. If we apply a stretch of scale factor K to our figure S, we can say that all the dimensions of figure S are multiplied by K.
So, if S represents the length of a bar, then after the stretch we will get a bar of length M, such that:
M = S*K
If that scale factor is 3/2, then we have the case of the problem:
M = (3/2)*S
We can isolate S in the above relation:
(2/3)*M = S
Now we have an equation (similar to the first one) that says that the scale factor from M to S is 2/3.
Then we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.
