Answer:
- <em><u>Given </u></em><em><u>,</u></em>
student's age = x years.
- <em><u>Also </u></em><em><u>,</u></em>
Teacher's age = 2x + 6
- <em><u>And </u></em><em><u>,</u></em>
Principal's age = 3x + 10
------------------------------------------
Difference between ages ,

therefore ,
second option is the correct answer.

Chrystelle bought 2/3 pound of ham. (given)
She bought 3/5 * 2/3 = 2/5 pound of cheese.
The cheese cost 4.95 per pound, so she paid 2/5*4.95 = 1.98 for the cheese.
The ham cost 5/3 * 4.95 = 8.25 per pound, so she paid 2/3*8.25 = 5.50 for the ham.
Her total purchase was 1.98 +5.50 = 7.48 for the ham and cheese.
Selections B, C, E are correct.
Answer:
7/56
Step-by-step explanation:
This is because there are 56 people and seven out of them are on the honor roll and have perfect attendance. You have a seven out of fifty-six chance of choosing them.
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><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.
