Answer:
x = 20
Step-by-step explanation:
→ Remember how many degrees are on a straight line
180°
→ Set up an equation
2x + 70 + 3x + 10 = 180
→ Simplify
5x + 80 = 180
→ Minus 80 from both sides
5x = 100
→ Divide both sides by 5
x = 20
The slope for A is 2/5 and the slope for B is -2/6
Answer:

Step-by-step explanation:
Given
Empty Tank

When filled with water, the height is:

Required
Determine how many more cubic inches needed
First, we calculate the difference between the height of the tank and the height of the water.


The volume of water to full the tank is then calculated as:
