A car covers 350 kilometre in 5 hours, how much distance does it cover in 7 hours?

Solve the system of equations. y= 2x y= x^2 - 15

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.
