2018 Test B Math · Question 8 of 57

$M=3N=\frac{P}{4}=Q+5=\frac{R}{7}> 0$

Based on the statement above, which variable has the greatest value

Show the answer

Correct answer: D

Break the equations apart to each equal $M$ :

$M=3N$

$M=frac{P}{4}$

$M=Q+5$

$M=frac{R}{7}$

Pick a number to substitute into the equations, and solve the equations to find the values of $M$ , $N$ , $P$ , $Q$ , and $R$ .

$N$ :

$N=frac{M}{3}$

$P$ :

$P=4M$

$Q$ :

$Q=M-5$

$R$ :

$R=7M$

Variable $R$ has the greatest value.
