A car traveled 36 miles in 45 minutes. the car traveled at a constant speed. it the car continues to travel at this rate which equation can be used to determine y the total number of miles the car will travel in hours?

What is x and y (use substitution? ) 5x+3y=38 and y=3x+8?

(a) solve h+2/6 = h-3/4(b) solve the following simultaneous equations. 2x = y + 66x - 2y = 13x = ? y = ?
