Answer:
50 degrees
Step-by-step explanation:
x + y = 90
x = 2y - 30
2y - 30 + y = 90
3y - 30 = 90
3y = 90 + 30
3y = 120
y = 120/3
y = 40
x = 2y - 30
x = 2(40) - 30
x = 80 - 30
x = 50 <====== angle x
-1/3x-7=y
Slope is equal to rise over run and b is where it touches the y axis
Answer:
D. b = r+z
Step-by-step explanation:
Given the expression b-r = z, we are to solve for b. To do this, we will add 'r' to both sides of the equation as shown;
b-r+r = z+r
Since -r+r = 0, substitute:
b+0 = z+r
b = z+r
Hence the resulting equation when r is added to both sides of the equation is b = z+r
Hence option D is correct
