Ross drives 256 miles in 4 hours. If Ross continues to drive at the same rate, how many miles can he drive in 12 hours?

768

Step-by-step explanation:

4 x 3 = 12

so 256 x 3 = 768

you can't solve x because it is 2 linear equation and you only have one equation

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
