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
EXPLANATION
The given inequality is,
By the definition of absolute value,
We divide through by negative 1, in the first part of the inequality and reverse the sign to get,
We simplify now to get,
Divide through by 2 to obtain,
Area of the triangle = 1/2 * base * <span>height
base = 16 in
</span>height = 16 in
Area = 1/2 * 16 * 16 = 128 in.
