X is t shirt is $8
Y is sweatshirt $11
2x+2y=38
3x+1y=35
We will be using the elimination process so you want even them out same value
2x+2y=38
-6x-2y=-70 ( want get rid of the y-value by increasing to other by when both add or subtract it will equal 0)
-4x=-32
Divide both -4
X=8 So 8 dollars a t-shirt so now will fill x with 8
2(8)+2y=38
16+2y=38
-16
2y=22
Divid by 2
Y = 11 so a sweatshirt is 11 dollars
You can check by fill each by the variable
Sandy. You take 3/10 and make it a decimal and that gives you .3 3/7 gives you .4 and 3/9 gives you .3.
Answer:
the perimeter would be 72
Step-by-step explanation:
I would think <span><span>6a/</span><span><span><span>27/5</span></span></span></span><span>=<span><span><span>10/9</span></span><span>a</span></span></span>
3 x 9 =27
27 - 5 = 22
To recheck
22+5 =27
27/9 = 3
