Answer:
the perimeter of a square is 4a.. where (a) is one side
therefore the equation formed is
3.5x(4)=2x+54
14=2x+54
2x= -40
x= -20
She could actually miss and get a 0 because 108+72+95/3=91
Hi Vanessa
3x -1/9 (27) =18
3x - 27/9 =18
3x- 3 =18
Add 3 to both sides
3x-3+3=18+3
3x=21
Divide both sides by 3
3x/3= 21/3
x= 7
The value of x is 7
Now let's check if my answer is correct
To check it we gonna replace x by 7 and 27 for y
(3)(7) -1/9 (27) = 18
21 -1/9 (27)=18
21- 27/9 = 18
21- 3 = 18
18 = 18
The answer is good and I hope its help:0
