hichkok12 [17]
X=price of one jumbo popcorn
y=price of one chocolate chip cookies

$5.00=$5.00(100 cts / $)=500 cts
$6.00=$6.00(100 cts / $)=600 cts

We suggest this system of equations:

x+2y=500
x+4y=600

we solve this system of equations by reduction method.

-(x+2y=500)
  x+4y=600
----------------------
      2y=100    ⇒ y=100/2=50

x+2y=500
x+2(50)=500
x+100=500
x=500-100
x=400

solution: one chocolate chip cookie cost 50 cts.

A right triangle has legs measuring 4.5 meters and 1.5 meters. The length of tge legs of a second triangle are proportional to t
Leviafan [203]
If the legs of both triangles are supposed to be proportional then they would be equal in length because that's what proportional means

so if the legs of one triangle are 4.5 and 1.5 then the other triangle "if proportional" would have legs with the same measurements which are 4.5 and 1.5

hope this answers your question
