Question 34

Multiple Choice

Solve graphically. In a concrete mix, there is four times as much gravel as concrete. The total volume is 15ft315 \mathrm { ft } ^ { 3 } . How much of each is in the mix if
X = the amount of concrete
Y = the amount of gravel
The equations are y=4xx+y=15\begin{array} { l } y = 4 x \\x + y = 15\end{array}
