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:
(3,-3)
Step-by-step explanation:
If a coordinate (x, y) is dilated by a factor k, the resulting coordinate will be (kx, ky)
Given the coordinate (1, -1), if dilated by a factor of 3, the resulting coordinate will be (3(1), 3(-1)) = (3, -3)
Hence the required coordinate will be (3,-3)
Answer:
-(20+z)/y = x
Step-by-step explanation:
-20=xy +z
Subtract z from each side
-20 -z = xy+z-z
-20 -z = xy
Divide each side by y
(-20 -z)/y = xy/y
Factor out a negative
-(20+z)/y = x
74 degrees
An angles value is 1/2 of the value of its corresponding arc. Angle x has the corresponding arc of 148, so it’s 148/2 or 74 degrees
