By using Pythagoreans Theorem: a^2 + b^2 = c^2
Answer:
27.4285714286
Step-by-step explanation:
You would divide 64 by 7 and multiply that by 3.
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
It’s 22 (add 6 after every term)
I need the a,b,c,d to answer this, you're asking "<u>which"</u> and I'm not given suggestions
