Answer 7

Wait.

Answer 8

The variation is at most 45.
Let's she burned 30 calories more than 450.
She burned 480.
What is the variation from 480 to 450?

Answer 9

im in a hurry cuz my mom is being a pain in the butt can you just pls give me the answer?

Answer 10

In this case the variation is 480 - 450 = 30
Notice you find the variation by subtracting, not adding.
Choice B has an addition inside the absolute value, so it is not the answer.
Also, notice that to find the variation, you need to subtract c - 450 and take the absolute value.

Answer 11

That points to this:
\(|c - 450| \le 45\)

Answer 12
