Step-by-step explanation:

To leave answer in positive exponents, just leave the answer inverse of the negative exponents.
Line graph is the correct answer
Answer:
Step-by-step explanation:
15- 17 = a
-2 = a
B = -8.3
c = 3/4 - 13/4
c = -10/4
c = -5/2
Answer:
60
Step-by-step explanation:
Since the angles A, D, and G are congruent then sum of given angles is eaqual to 180 degrees
x + 20 + 2x + x = 180 add like terms
4x + 20 = 180 subtract 20 from both sides
4x = 160 divide both sides by 4
x = 40
Angles B, E, and H are congruent so E is also = x + 20 and x = 40 so angle R = 60
