Step-by-step explanation:

Step 1: Define

6x + 4 = 5x + 17 + 120

Step 2: Solve for x

Combine like terms: 6x + 4 = 5x + 137
Isolate x terms: x + 4 = 137
Isolate x: x = 133

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 6(133) + 4 = 5(133) + 17 + 120
Multiply: 798 + 4 = 665 + 17 + 120
Add: 802 = 682 + 120
Add: 802 = 802

Here we see that 802 does indeed equal 802.

∴ x = 133 is the solution to the equation.

Answer:

$\displaystyle (-∞, 2\frac{1}{3}) ∪ (1, ∞) \\ \\ 2\frac{1}{3} > t \:OR\: 1 < t$

Step-by-step explanation:

3t + 2 < 7 OR −4t + 5 < 1

- 2 - 2 - 5 - 5

Your company maintains a cylindrical oil refinery storage tank that is 190 feet across on the inside and 80 feet high. The tank

Lorico [155]

Answer:

The correct answer is A. You multiplied that tank's radius by two instead of calculating r²

Step-by-step explanation:

This is the wrong calculation we did:

Volume of the cylindrical oil refinery storage tank = π * 2r * h * 0.75

Replacing with the real values, we got:

Volume of the cylindrical oil refinery storage tank = 3.14 * 2 * 95 *80 * 0.75

Volume of the cylindrical oil refinery storage tank = 35,796 cubic feet (Rounded 35,800)

This is the correct calculation we should have done:

Volume of the cylindrical oil refinery storage tank = π * r² * h * 0.75

Replacing with the real values, we got:

Volume of the cylindrical oil refinery storage tank = 3.14 * 95² *80 * 0.75

Volume of the cylindrical oil refinery storage tank = 1'700.310 cubic feet
