Answer:15
Explanation:Since these are similar triangles it means each contrasting side length has a ratio and the ratio for the side lengths is 1:3 based on 4:12 so you would multiple the side length of Db times 3 to find Ed and your answer is 15
-4m-24=-8
(add 24 to both sides)
-4m=16
(divide by -4 on both sides)
m=-4

Answer:
10 gallons of gas.
Step-by-step explanation:
250/9 = how many miles 1 gallon of gas will take
250/9 = 27.78
1 gallon of gas = 27.78 miles
275/27.78 = 9.90 gallons
9.90 gallons round up to 10 gallons
Therefore, Trey would need 10 gallons of gas to drive 275 miles.
