Max was on vacation twice as long as Jared and half as long as Wesley. The boys were on vacation a total of 3 weeks. How many da
GuDViN [60]
Lets say W=Wesley, M=Max, and J=Jared.
So your equations are M=2J, 2M=W, and M+J+W=21days(3 weeks)
So substituting M and W into M+J+W=21 gives you 2J+J+2M=21, substitute M again, to get 2J+J+4J=21 so you get 7J=21 so J= 3 days. Using J=3, substitute in to find M, using M=2J, so M=2(3) so M=6 and using that, substitute into 2M=W, so 2(6)=W so W=12. And 12+6+3=21 to check.

Anyone here who can help me with this?
Mandarinka [93]

Answer:

D. 16 years old

Step-by-step explanation:

<u>Step 1:</u> Let T be Tien's age and J as Jordan's age (today),

T=\frac{1}{4}J

<u>Step 2:</u> Let T be Tien's age and J as Jordan's age (in 2 years),

T+2=\frac{1}{3} (J+2)

T=\frac{1}{3}(J+2)-2

<u>Step 3:</u> As their age differences will always be similar we can have the two equations above equal to find Jordan's age,

\frac{1}{4} J=\frac{1}{3}(J+2)-2\\\frac{1}{4}J-\frac{1}{3}J=\frac{2}{3}  -2 \\-\frac{1}{12}J= -\frac{4}{3} \\\\J=16
