<span>The entire expression should be subtracted from 30. To subtract the quantity, distribute the negative sign, which changes the signs on the terms. So, the –2 changes to positive and gets added to 30 instead of subtracted from it.
Hope this helps! ^^</span>

Answer:
46
Step-by-step explanation:
Given Information:
Volume of truck = 15 ft³
Area of base of container = 6 ft²
Required Information:
Height of truck = h = ?
Answer:
Height of truck = h = 2.5 ft
Step-by-step explanation:
The volume of the truck is given by
V = l*w*h
Where l is the length, w is the width, h is the height
The area of the base of container is given by
A = l*w
Where l is the length and w is the width.
Substitute the equation of area into the volume of the truck equation.
V = l*w*h
V = (A)*h
Re-arrange for the height,
h = V/A
h = 15 ft³/6 ft²
h = 2.5 ft
Therefore, the height of the clothing truck is 2.5 ft.
Answer:
Age of Rocky = 5 months
Step-by-step explanation:
Given that:
Equation for calculating puppy's weight
p = 3a + 2
Here,
p = weight of puppy
a = age in months
We have to find the age if the weight is 17 pounds
Putting p=17 in given equation
17 = 3a + 2
17 - 2 = 3a
3a = 15
Dividing both sides by 3
Hence,
Age of Rocky = 5 months
