Step-by-step explanation:
<u>Step 1: Define Equation</u>
6n + 7 = 55
<u>Step 2: Solve for </u><em><u>n</u></em>
- Subtract 7 on both sides: 6n = 48
- Divide 6 on both sides: n = 8
<u>Step 3: Check</u>
<em>Plug in n into the original equation to verify it's a solution.</em>
- Substitute in <em>n</em>: 6(8) + 7 = 55
- Multiply: 48 + 7 = 55
- Add: 55 = 55
Here we see that 55 does indeed equal 55.
∴ n = 8 is a solution of the equation.

Answer:
A)50°F = 10°C
B)75°C = 167°F
C)-40°C = -40°F
Step-by-step explanation:
A) 50°F = 10°C
Formula
(50°F − 32) × 5/9 = 10°C
B) 75°C = 167°F
Formula
(75°C × 9/5) + 32 = 167°F
C) -40°C = -40°F
Formula
(-40°C × 9/5) + 32 = -40°F
