Find the solution of this system of equations. Separate the x- and y-values with a comma.
x + 10y = -18
x - y = 4

the answer is a

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

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
