The volume (V) of prism is the product of the area (A) of the base and its height (h). The area of the square base is the square of its width, 3 cm.
144 cm³ = (3 cm)² x h
The value of h from the equation is 16. Therefore, the height of the prism is 16 cm.

Answer:
Each month you should save $ 150
Step-by-step explanation:
First, the earnings are given per year, so we need to transform $36000/year into dollars per month. So, using a rule of three as following, we obtain:
$ 36,000 ------------- 12 months
X -------------- 1 month
Solving for X, we get:
X = $ 3,000 /month
it means that earn $36,000/year is equivalent to earn $3,000/month
Now, we need to find the 5% of $3,000, this can be calculated making the following multiplication:
Then, each month you should save $150

Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
