Answer:
3x +89 + 8x + 58 =180 (they are supplementary angles, so added together they are equal to 180)
11x + 147= 180 (combine like terms on the left side of the = sign)
11x= 33 (subtract 147 from both sides and then divide by 11 to isolate x)
x= 3 (this is x)
3x +89 (this is the measure of angle MON, plug in x and solve)
3(3)+89
9+89
98 degrees (this is your answer)
Step-by-step explanation:
You must trade in 3 books to gain 2 from the store. If she brings 18 books, 18/3 shows that she can turn in 6 "groups" of 3 books. Each "group" gets her 2 books, and since 6*2=12 she can get 12 books from the store.
