The answer is D: 8
3/9=p/24
9p=24x3
9p=72
p=72/9
p=8
6x3+3=21 there are 3 pieces of 6 inch ribbon which gives us the 6x3 and 1 piece of the 3 inch ribbon which makes us add 3
Answer:
D (9,3)
Step-by-step explanation:
just did the quiz/test.
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
