Answer:
30 and 6
Explanation:
Let the numbers be x and y. Then
<span>x+y=36</span>
<span>x−y=24</span>
Adding the two equations together gives
<span>2x=60</span>
<span>∴x=30</span>
Substituting this back into either of the equations gives <span>y=<span>6</span></span>
So for this question (for finding x and y) you will want to use elimination. To do this you will need to bring the x and y to the same side (I put them on the left):
-3/2x+y=6
x+y=0
Now subtract the y on the bottom from the top to isolate x:
3/2x=6
Now the easiest way to bring over the 3/2 to isolate the x fully is to convert it to decimal (1.5) and divide it by 6 (because when multiplication on one side of problem the only way to bring it over is to divide):
x=6/1.5
which simplifies to:
x=4
Hope this helps!

D both are right triangles
Well 3 feet=1 yard
so the conversion factor is 3ft/1yd
so 12 yards converted to feet is
12yd times 3ft/1yd
the yd will cancel and you will be left with 36 feet
each banner is 1 foot so 36/1=36
she can make 36 banners
