1/5 (18-11) I believe this is what you mean?
Answer:
x= -17
Step-by-step explanation:
When we have 2 points, we can find the slope using
m = (y2-y1)/(x2-x1)
Substituting what we know
1/5 = (0-3)/(x--2)
1/5 = -3/(x+2)
Using cross products
1*(x+2) = 5*(-3)
x+2 = -15
Subtract 2 from each side
x+2-2 = -15-2
x=-17
Answer:
12
Step-by-step explanation:
There are many ways to approach this problem. I like a method that uses the least amount of computation. We could figure how much Wendy makes on a bag of chips, the additional amount Wendy wants to make, then divide the latter by the former to find the number of additional bags to sell.
We could use a proportion to figure the number of bags corresponding to $126 in earnings, then subtract the 72 bags already sold. Essentially, we will do this, but without the intermediate numbers.
__
The additional fraction of 72 bags will be ...
(126/108) -1 = 18/108 = 1/6
Then Wendy must sell an additional ...
(1/6)×(72 bags) = 12 bags
to increase her earnings to $126.
P= a+b+c = 76
side a = 2b = 30
side b = b = 15
side c = 2b + 1 = 31
101.28-96 = 5.28
5.28/96 = 0.055
0.055 x 100% = 5.5%
