L = 4w + 9.7
2l + 2w = 91.4
2(4w + 9.7) + 2w = 91.4
8w + 19.4 + 2w = 91.4
10w = 72
w = 72/10 = 7.2 cm
l = 4(7.2) + 9.7 = 38.5
Dimension = 38.5 by 7.2
Let x be the number of days for which the costs are the same, then
110 + 46x = 70 + 54x
54x - 46x = 110 - 70
8x = 40
x = 5
Therefore, it will take 5 days for the cost to be the same.
Answer:
The slope is -3
Step-by-step explanation:
The equation is in y=mx+b form where m is always the slope. In this case, m=-3, therefore that is the slope
5 3/5 because you multiply the top number by 7
