Answer:
Step-by-step explanation:
Both angles added together = 180 degrees. They both have a straight line as their base.
So let <ABC = x
Then <CBD = 3x Add the two angles
x + 3x = 180 Combine
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
So 3x = 3*45 = 135
Answer:
Step-by-step explanation:
3y + 1 - 2y = -3 -3y
4y = -4
y = -1
What grade is that is that 4th or 5th grade
Answer:
P = 5.5x + 9
Step-by-step explanation:
P = 5x + (0.3x + 24) + (0.2x - 15)
reduced
P = 5.5x + 9
