It is m + 9 because if we let m = 60 and the lest was 9 minutes longer than m, the test would be 69 minutes long. Therefore the answer is m + 9
56 miles
If Lou ran 72 more miles than lee. Just subtract 72 from 128 (128-72) and you get 56.
Answer:
x = 28
m∠ACD = 68°
Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
x = 28
m∠ACD = 180 - 4(28) = 180 - 112 = 68°
Thats hard bro hopefully somebody helps you figure it out
First you need to find the middle number, wich is 75. Since there is no $75, I would go with $80.
