Step-by-step explanation:

Answer:

-3.8x + 7 and c = -75/14 and/or c = -5.35714

Step-by-step explanation:

First equation:

1.2x + 7 - 5x =

Step 1 - Group like terms:

1.2 - 5x + 7

Step 2 - Add simliar elements:

1.2 x - 5x = -3.8x =

3.8x + 7

Answer: -3.8x + 7

Second equation:

2.2c - 3 = 2(6 - c) + 7c =

Step 1 - Multiply both sides by 10:

2.2c ⋅ 10-3 ⋅ 10 = 2(6 - c) ⋅ 10 + 7c ⋅ 10

Step 2 - Refine:

22c - 30 = 20(6-c) + 70c =

- Expand 20(6-c): 120 - 20c

22c - 30 = 120 - 20c + 70c

Step 3 - Add similar elements:

-20c + 70c = 50c =

22c - 30 = 120 + 50c

Step 4 - Add 30 to both sides:

22c - 30 + 30 = 120 + 50c + 30

Step 5 - Simplify:

22c = 50c + 150

Step 6 - Subtract 50c from both sides:

22c - 50c = 50c + 150 - 50c

Step 7 - Simplify:

-28c = 150

Step 8 - Divide both sides by -28:

-28c/-28 = 150/-28

Step 9 - Simplify:

c = -75/14

Answer:

Fraction form: c = -75/14

Decimal form: c = -5.35714

Solve for  g  by simplifying both sides of the equation, then isolating the variable.

Answer:

g = 14

Step-by-step explanation:

Answers

Answer:

118

Step-by-step explanation:

Answer:

The answer is 118 laps.
