Answer:

79.5 + 5.5x = Y

Step-by-step explanation:

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

79.5 + 5.5t = Y

B. 4.5=2m+g
f. 9.25=3m+2g

1.25=m

sub

b. 4.5=2(1.25)+g
f. 9.25=3(1.25)+2g

b. 4.5=2.5+g
f. 9.25=3.75+2g

minus 2.5 from both sides on the b. equaion and minus 3.75 from both sides on the f. equation

b. 2=g
f. 5.5=2g

divide both sides of f. equation by 2

b. 2=g
f. 2.75=g

2.75-2=0.75
