S= savings before she bought the dress s - $55 would be her new balance after she bought the dress.
We could also talk about her savings now (after her purchase). If we let n=now
n + $55 would be her balance before she bought the dress.
Hi there!
9 + 1/2 (7n - 26) - 8n
= 9 + 7n*1/2 - 26*1/2 - 8n
= 9 + 3.5n - 13 - 8n
= 9 - 13 + 3.5n - 8n
= -4 + 11.5n
Hope this helps!
14/10 is 1.4 , 1.4/ 0.2 is 7 so 0.2 is the answer
18x6 = 108
110-108 =2
By weeks 6 she will only have $2 left
So being realistic, at week 7 she will have spent all her money.
3x - 5 = 1/2x + 2x 3x - 5 = .5x + 2x3x - 5 = 2.5x-3x = -3x -5= -.5x divide by -.5 on both sidesx = 10
