Multiply 2/10 by 3/1 and you should end up with 6/10
Answer:
C
Step-by-step explanation:
Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7
I think it might be false, I could be wrong though.
Hopefully that helped! :)
P = 4x + 2(x + 5)
That’s the expression
P = perimeter
