Step-by-step explanation:
<u>Step 1: Define Equation</u>
4x - 8 = 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 8 to both sides: 4x = 24
- Divide 4 on both sides: x = 6
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 4(6) - 8 = 16
- Multiply: 24 - 8 = 16
- Subtract: 16 = 16
Here we see that 16 does indeed equal 16.
∴ x = 6 is the solution to the equation.
Answer:
14.1509717
Step-by-step explanation:
c²-b² = a²
19.5²-6² = a²
a²-12²= x² = 200.25
square root 200.25
X = 14.1509717
20 -- 55
1/8 -- x
(1/8)*55/20=55/160≈0.34 feet
