solve for x
2x -2 =0

x = 1

Step-by-step explanation:

2x -2 = 0

you make the 2 positive and add it to the zero like this

2x = 0

+2

than you get 2x =2

that divide 2x by 2 and its 1

and it will be x=1

5.2 kg per month.

Explanation:

The measure of how fast the wrestler gained weight, in kg per month, is the  weight gain rate.

The table is:

Time (months)           Weight (kg)

    0.5                             80.6

    2                                 88.4

    3.5                              96.2

The weight gain rate, WGR, for a period may be calculated as:

WGR = [ weight gain ] / [period]WGR = [final weight - initial weight] / [final time - initial time]WGR₁ = [88.4 kg - 80.6 kg] / [2 month - 0.5 month] = 7.8 kg / 1.5 month = 5.2 kg / monthWGR₂ = [96.2 kg - 88.4 kg] / [3.5 month - 2 month] = 7.8 kg / 1.5 month = 5.2 kg / month.

As you see, the wrestler gained weight at a constant rate of 5.2 kg per month.
