-4x + 6 = 3x - 36 How do I solve this

LekaFEV [45]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

-4x + 6 = 3x - 36

Step 2: Solve for x

Add 4x to both sides: 6 = 7x - 36
Add 36 to both sides: 42 = 7x
Divide both sides by 7: x = 6

Step 3: Check

Plug in x to verify it's a solution.

-4(6) + 6 = 3(6) - 36

-24 + 6 = 18 - 36

-18 = -18

The diagram shows the dimensions of a teepee. Find the volume of the building to the nearest cubic unit. Use 3.14 for pi.

LekaFEV [45]

The volume of a cone uses the following formula:

$V = \pi r^{2} \frac{h}{3}$

Our diameter is 20 feet, so divide this by 2 to find the radius:

$20 \div 2 = 10$

We now have all of our values need to fill in the formula. Plug in these values:

$\pi = 3.14, r = 10, h = 17$

$3.14 * 10^{2} * \frac{17}{3}$

$3.14 * 100 * 5.67$

$314 * 5.67 = 1780.38$

The volume of the cone is 1780 cubic feet.

40/16 = 24/x

16*24 = 384

x = 384 / 40

x =9.6
