Answer:
7
Step-by-step explanation:
Y is going to be the number 40
x will equal 90
Dory = 11 x Carly
Together => d + c = 156
11c + c = 156
12c = 156
C = 156 : 12
C = 13
Carly biked 13 miles
Dory = 11 x c = 11 x 13 = 143 miles
Prove
143 + 13 = 156 miles together
Answer:
-6
Step-by-step explanation:
r = 9, b = 5, g = -6

Combine like terms in the brackets
[6]*[-1]
6 times -1 equals -6, so that is your answer
