Answer: C
Step-by-step explanation:
Whenever you're interested in computing the (absolute) difference between two values of a certain variable, you have to subtract the final value and the initial value. This is often written as delta:

So, in this case, the final temperature is -30°F. The initial temperature is 115°F. So, the variation is

A negative delta indicates that the value decreased, which is our case.
Answer:
BC = 60
Step-by-step explanation:
3X + X = 80 <---- X = BC
3X + X = 4X
4X = 80 <---- DIVIDE BOTH SIDES BY 4
4X ÷ 4 = X
80 ÷ 4 = 20
20 × 3 = 60
