let y = the smaller number

one number is 4 more than another and their sum is 60. write the system of equations that could be used to solve the problem.

add 5 subtract 1

step-by-step explanation:

if x = 1, then the answer is 3.5

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
