The distance that sarah travels varies directly to how long she drives. she travels  440  miles in  8  hours. 
write the equation that relates the distance,  d, to the time,  t.
how many miles can sarah  travel in 6 hours

440/8 will get you how many miles Sarah travel in 1 hour.

But Sarah travels 55 miles in 1 hour.

Sarah can travel 330 miles in 6 hour.

d=55t  Sara travels 330 miles

Step-by-step explanation:

We are given that distance, d, Sarah drives varies directly to the time, t. This means

d=k⋅t

for some constant, k. Since Sarah travels 440 miles in 8 hours, we substitute these values into the formula for direct variation to find

440=k⋅8

Dividing by 8 gives k=55, so an equation that relates d and t is

d=55t

Substituting t=6 yields

55(6)=330

So Sarah can travel 330 miles in 6 hours.

uhhh idk u yolo?

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
