Answer:
x = 30
y = 14
Step-by-step explanation:
If the linear pairs are equal, then we can conclude that the angle on each of the sides is 90
Thus 3x = 90
and x = 90/3 = 30
Also;
9y - 36 = 90
9y = 90 + 36
9y = 126
y = 126/9
y = 14
Answer:
c)
subtract 5 times the second equation from 2 times the first equation
Step-by-step explanation:
subtract 5 times the second equation from 2 times the first equation
This will make the coefficient of the y variable 10
for both equations
10y - 10y = 0
leaving only x
Answer:
187.5
Step-by-step explanation:
Answer= 16x -20y
Perimeter of a square= 4( Side length)
Therefore, 4(4x -5y)
= 16x -20y
I think that is it cuz e can’t solve it any further
