Answer:

x=1/2

Step-by-step explanation:

-5(x - 4) + 6 = 5(3x+4) -4

WE APPLY DISTRIBUTIVE PROPERTY:

-5*x +5*4 + 6 = 5*3x +5*4 -4

-5x + 26 = 15x +20 -4

26 +4 -20=15x+5x

10=20x

x= 10/20

we have:

x=1/2

If you can travel 120 miles in 3 hours (180 minutes), what is the distance you could travel in 75 minutes

andreyandreev [35.5K]

Answer:

$Speed = \frac{Distance}{Time } = \frac{120}{3} = 40mph$

T = 75minutes = (75/60) hours

$Distance = Speed \times Time = 40 \times \frac{75}{60} =\frac{40\times 75}{60} = 50miles$

option A
