Step-by-step explanation:
A/2 = 4
A = 4 x 2
A = 8
I think this should be the answer
Answer:
(8,-9)
Step-by-step explanation:
using the principle of vectors, you match each number to their coordinates and add them
so we have (7+1,-12+3)
which is equal to (8,-9)
3x+40=100
subtract 40 from both sides
3x= 60
divide by 3
x=20
each Sweater cost 20
The answer should be when X=1
Hope this helped u out if not sorry
