The wrestler gained 5.20 kilograms per month.
Step-by-step explanation:
Let,
x be the weight gained every month.
y be the original weight before weight gain.
According to given statement;
0.5x+y=80.6 Eqn 1
2x+y=88.4 Eqn 2
3.5x+y=96.2 Eqn 3
Subtracting Eqn 1 from Eqn 2

Dividing both sides by 1.5

The wrestler gained 5.20 kilograms per month.

Answer:
8.5
Step-by-step explanation:
10x+2=9x(3)
10x+2=27x
2=17x
x=8.5
Answer:
D) 8
Step-by-step explanation:
3x - 7 - 2x + 5 = 6
3x - 2x = 6 + 7 - 5
x = 8
Note: 6 + 7 -5 = 13 -5 = 8
