Answer:
x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
therefore your answer is x = -1 and y = 18
3:13 - 1:00 = 2:13
2:13 - 0:37 = 1:36
1:36 is your answer.
Glad I could help, and good luck!

Answer:
Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
substitute the given values
solve for x
Find the angle measurements
The slope is the number besides x which in this case is 14 while your t intercept is 9
