$55.50
Step-by-step explanation:
150 (0.37) = 55.5
Answer:
x = 22
Step-by-step explanation:
Step 1: Write equation
2(x + 9) = 4(x - 7) + 2
Step 2: Solve for <em>x</em>
- Distribute: 2x + 18 = 4x - 28 + 2
- Combine like terms: 2x + 18 = 4x - 26
- Subtract 2x on both sides: 18 = 2x - 26
- Add 26 to both sides: 44 = 2x
- Divide both sides by 2: 22 = x
- Rewrite: x = 22
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
2(22 + 9) = 4(22 - 7) + 2
2(31) = 4(15) + 2
62 = 60 + 2
62 = 62
Volume of a cone = (1/3) * Area of Base * height
144 * 3 / 9 = Area of Base
Area of the Base = 48
