In the equation x + 8.2 = –12.7, 8.2 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation?

Subtract –12.7 from both sides. The solution is 20.9.

Add –12.7 to both sides. The solution is –4.5.

Subtract 8.2 from both sides. The solution is –20.9.

Add 8.2 to both sides. The solution is –4.5.

Step-by-step explanation:

1. 6.1. 6.1 mph

1.5. 9.15. 6.1 mph

2. 18.3. 9.15 m

2.5. 45.75. 18.3

Time = distance/speed

Step-by-step explanation:

(1.5)*(6.1) = 9.15

(2)*(9.15) = 18.3. 18.3/2=9.15 mph

(2.5)(18.3)=45.75. 45.75/2.5=18.3
