Hello! So in order to solve this problem, it's best to start off making an equation. $18 + $.15x = $29.25
In this equation x represents the number of minutes she used. So now, we just have to solve for x.
First subtract $18 from both sides. Your new equation will be $.15x = $11.25. Then divide both sides by $.15 to get x by itself. $11.25/$.15 = 75.
So we can conclude that Bella spoke on the phone for 75 minutes this last month. Hope this helps!
Answer:
Step-by-step explanation:
Answer: 99 square cm
Step-by-step explanation:
you cut the height in half, so 6 divided by 2 = 3, if you do that you have to do the same to the width, so again 6 divided by 2 = 3, the length stays the same, so the equation would be 3 X 3 X 11 = 99

2 t - 2
= 3 (t+2)
or

Pythagorean Theorem .. 2.2^2 + 16.8^2 = c^2
287.08^2 = c^2
16.9 = c
This is the approximate distance from the boat to the town.
