Answer:

C

Step-by-step explanation:

First of all -2-5= -7

It isn't (A) because (A) is saying that the beginning temperature was a postive number, which it wasn't The beginning temperature is -2, which is negative. So we can cross that off.

It isn't (B) because (B) is saying that you start off with -2 and then it gets warmer, and temperature adds up onto it. When you do -2 +5, you get 3, which is not the answer.

So, the answer is c

Proof: It starts of with negative 2, which is the first temperature. Then, it says decreased by 5, which is what is happening. 5 is getting subtracted from -2

So, the answer is C

How many garbage cans should be placed in each campground? Explain how you can use addition or multiplication to find the answer
Vikentia [17]

Answer:

Step-by-step explanation:

Multiplication

Ratio of Tables to garbage = 8:3

Small camp ground:

40 picnic tables and let x be the number of garbage cans

\frac{8}{3}=\frac{40}{x}\\\\\frac{8*5}{3*5}=\frac{40}{x}\\\\\frac{40}{15}=\frac{40}{x}\\\\

x = 15

Small campground with 40 picnic table needs 15 garbage cans

Large picnic ground:

120 picnic tables and let y be the number of garbage cans

\frac{8}{3}=\frac{120}{y}\\\\\frac{8*15}{3*15}=\frac{120}{y}\\\\\frac{120}{45}=\frac{120}{y}

y= 45

Big campground with 120 picnic table needs 45 garbage cans
