Answer:
C
Step-by-step explanation:
First, determine the amount it takes- in this case, it's 82.5 miles. To find out the gallons he'll need to use, divide it by 30 to get 2.75 gallons. 3.05 times 2.75 is 8.3875, rounding to $8.39.
Answer:
42.5
Step-by-step explanation:
First find out what 1 unit equals on the second number line
34/4=8.5 so 1 unit = 8.5 dollars
the questions asks for 5 units so
8.5 * 5 = 42.5
<u>OR</u>
4/34=5/x
4x=34(5)
4x=170
x=42.5
Answer:
Step-by-step explanation:
The given equation is A=4 πr².
We need to solve the above equation for r².
We have,
A=4πr²
Dividing both sides by 4π, we get :
Hence, the value of r² is equal to 
.
Answer:
x=-3
Step-by-step explanation:
Given: 2(x+1)=3x+5
Distributive Property: 2x+2=3x+5
Subtract 2x on both sides: 2=x+5
Subtract both sides by 5: x=-3
Therefore, x=-3
