Answer:

m = 4

Step-by-step explanation:

Given

- 2(m + 3) - 5m = - 34 ← distribute and simplify left side

- 2m - 6 - 5m = - 34

- 7m - 6 = - 34 ( add 6 to both sides )

- 7m = - 28 ( divide both sides by - 7 )

m = 4

A plane can fly 1440 miles in the same time as it takes a car to go 400 miles. If the car travels 130 mph
patriot [66]

Answer:

The speed will be "144 mph".

Step-by-step explanation:

Let the speed of the plane be "x mph".

then,

The car's speed be "x-130 mph".

According to the question,

⇒ \frac{1440}{x} =\frac{400}{x-130}

By applying cross-multiplication, we get

⇒    1440(x-130)=400x

⇒ 1440x-187200=400x

⇒    1440x-140x=187200

⇒                1300x=187200

⇒                       x=\frac{187200}{1300}

⇒                          =144 \ mph
