Naddik [55]

Answer:

The answer is: both class have the same ratio.

Step-by-step explanation:

Get the ratio of tall to short. Divide Tall by Short:

Jack's class:

18/10 = 1.8 tall one for every short one

Michael's class:

54/30 = 1.8

The ratio is the same!

You can further prove this by multiplying 18 times 3 and getting 54, and 10 times 3 and getting 30.

Hope this Helps!! Have an Awesome Day!! (-:

erastova [34]

x - price of a video tape

y - price of a DVD

\left\{\begin{array}{ccc}2x+3y=134\\x+5y=179&|\text{subtract 5y from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}2x+3y=134\\x=179-5y&|\text{substitute to the first equation}\end{array}\right\\\\2(179-5y)+3y=134\qquad\text{use distributive property}\\\\(2)(179)+(2)(-5y)+3y=134\\\\358-10y+3y=134\qquad\text{subtract 358 from both sides}\\\\-7y=-224\qquad\text{divide both sides by (-7)}\\\\\boxed{y=32}\\\\\text{Put the value of y to the second equation}\\\\x=179-5(32)\\\\x=179-160\\\\\boxed{x=19}
