Question

Someone help What is 3.5=12s-55

Answer 1

Answer:

4.875 = s

Step-by-step explanation:

3.5=12s-55

Add 55 to each side

3.5+55=12s-55+55

58.5 = 12s

Divide each side by 12

58.5/12 = 12s/12

4.875 = s

Answer 2

Answer:

s = 4.875

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Step-by-step explanation:

Step 1: Define equation

3.5 = 12s - 55

Step 2: Solve for s

1. Add 55 to both sides:                    58.5 = 12s
2. Divide 12 on both sides:                4.875 = s
3. Rewrite:                                           s = 4.875

Step 3: Check

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

1. Substitute in s:                    3.5 = 12(4.875) - 55
2. Multiply:                               3.5 = 58.5 - 55
3. Subtract:                              3.5 = 3.5

Here we see that 3.5 does indeed equal 3.5.

∴ s = 4.875 is a solution of the equation.
