whats w stand for? -7w + 3(w+2)= -14
509w
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter
Let's start with making the variables coefficient a positive number. This obtained by simply multiply the negative fraction by -1/1, which results in the same fraction just positive. However, what you do to one side you must always do to the other. -2/7w = 8 -1/1 x -2/7w = 8 x -1/1 = 2/7w = -8 Now we see that our variable is still attached to the coefficient by means of multiplication. We must perform the inverse operation to detach the variable. In our case, division will suffice. 2/7w ÷ 2/7 = -8 ÷ 2/7 1/w = -8 ÷ 2/7 1/w = -28 w = -1/28. Is it (-2 over 7)w or -2 over (7w)?
-63=7w

Ill assume you mean for an are of a rectangle. w will stand for width. So you know the equation for a rectangle is L*W, so if length is 7W, then the area is 7W*W=Area or 7W^2
509w
7w - 4w - 6w = (7 - 4 - 6)w = -3w
7w=122 122/7= 17.43 w=17.43
As a term of an expression in math, 72w means 7 times w
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter
It is: 7+w
-36 + 2w = -8w + w -36 + 2w = -7w -36 = -7w - 2w -36 = -9w w = -36/-9 = 4
