Answer:

Step-by-step explanation:

x1 = 20 ; y1 = 12

x2 = ? ; y2 = 5

$\frac{x_{1}}{x_{2}}=\frac{y_{2}}{y_{1}}\\\\\frac{20}{x_{2}}=\frac{5}{12}\\\\20 *12 = x_{2}*5\\\\\frac{20*12}{5}=x_{2}\\\\4*12=x_{2}\\\\x_{2}=48$

Michelle is 7 years older than her sister Joan, and Joan is 3 years younger than their brother Ryan. If the sum of their ages is

Zielflug [23.3K]

Answer:

Step-by-step explanation:

We can create a systems of equations. Assuming $m$ is Michelle's age, $j$ is Joan's age, and $r$ is Ryan's age, the equations are:

$m = j + 7$

$j = r-3$

$m+j+r = 64$

We can use substitution, since we know the "values" of m and j.

$(j+7)+(r-3)+r = 64\\(j+7)+(2r-3)=64\\2r + j + 4 = 64\\2r + j = 60\\\\$

$r = 21, j = 18$

So we know that Joan is 18 years old.

Hope this helped!
