Let WWW represent the sumo wrestler's weight (in kilograms) after ttt months.
Complete the equation for the relationship between the weight and number of months w=?

Answer 1

79.5 + 5.5t = W

Step-by-step explanation:

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He gained weight at a rate of 5.5 kilograms per month. After 11 months, he weighed 140 kilograms. Let W represent the sumo wrestler's weight (in kilograms) after t months.

Sumo wrestler gained 5.5 kg per month

After 11 month, he weighed 140 kg.

Let x be his current weight.

Then x + 11(5.5) = 140

   x = 140 - 60.5

   x = 79.5

If W is the weight of the wrestler after t months, then the linear equation would be:

  79.5 + 5.5t = W
