Define x:
----------------------------------------------------------------
Let the number be x
----------------------------------------------------------------
Construct Equation :
----------------------------------------------------------------
x- 18 = 7x
----------------------------------------------------------------
Take away x from both sides :
----------------------------------------------------------------
-18 = 7x - x
----------------------------------------------------------------
Combine like terms :
----------------------------------------------------------------
-18 = 6x
----------------------------------------------------------------
Switch sides :
----------------------------------------------------------------
6x = -18
----------------------------------------------------------------
Divide by 6 on both sides :
----------------------------------------------------------------
x = -3
----------------------------------------------------------------
Answer; The number is -3.

Box A : 8.25
Box B : 8.2
Box C : 8.225
Box D : 8.05
heaviest box is box A
Answer:
B is 2.
Step-by-step explanation:
4 x 2 is 8.
8 + 14 is 22.
Perimeter = 2w + 2l
Since its a square, the length and width are equal therefore:
2(s + 3) + 2(s + 3) = Perimeter
You can simplify this into a variety of ways:
1. 4(s + 3)
2. 2s + 6 + 2s + 6
3. 4s + 12
