Answer:
Number of miles traveled by Mary to work = 7 miles
Step-by-step explanation:
total distance traveled on the Map by Mary = 1 + 2.5 = 3.5 cm
Scale of the map = 2 cm = 4 miles
Hence 3.5 cm = (3.5 x 4) ÷ 2 = 7 miles

Answer:
g = 1/2
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
9 + 3.5g = 11 - 0.5g
<u>Step 2: Solve for </u><em><u>g</u></em>
- Add 0.5g on both sides: 9 + 4g = 11
- Subtract 9 on both sides: 4g = 2
- Divide 4 on both sides: g = 1/2
<u>Step 3: Check</u>
<em>Plug in g into the original equation to verify it's a solution.</em>
- Substitute in <em>g</em>: 9 + 3.5(1/2) = 11 - 0.5(1/2)
- Multiply: 9 + 1.75 = 11 - 0.25
- Add/Subtract: 10.75 = 10.75
Here we see that 10.75 does indeed equal 10.75.
∴ g = 1/2 is a solution of the equation.
