The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28. Which solution can be used to fill i
n both blanks in the table? (2, 5) (5, 2) (5, −8) (−8, 5)
2 answers:
Answer: (5,2)
Step-by-step explanation:
Given equations: 
Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get

Adding equation (3) and (4), we get

Substitute x=5 in equation (4), we get

Hence, the solution of the both equations is (5,2).

ABC is same as FDE
so AC = FE = 5ft
angle B = 28 deg
angle C = 90 deg
so A = 180 - B - C = 62
7.
If c = 16
that means the equation is
16 - 9
which is 7
so 7
Answer:
27/10
Step-by-step explanation:
(180-x) + 18 + 30 + x/2 = 180
=> 180 + 48 - x + x/2 = 180
=> -x/2 + 48 = 0
=> x/2 = 48
=> x = 48×2 = 96°
