A negative and a negative together make a positive so you are basically adding. so you have to find a common denominator which is 8 so you end up with 5/8 + 6/8 = 11/ 8 = 1 and 3/8
30-f+8f=30
30+7f=30
Move +30 to the right side. Sign changes from +30 to -30.
30-30+7f=30-30
7f=0
Divde by 7
7f/7=0/7
Cross out 7 and 7, divide by 7. Becomes 1*1*f=f
f=0
Answer: f=0
Answer:
33 chips
Step-by-step explanation:
c= (700 - 464) ÷ 7 = 33
She can use 33 chips or less. I less cause she shouldn't eat too much calories.

Find out the what is the perimeter of the rectangle .
To prove
Now as shown in the figure.
Name the coordinates as.
A(−3, 4) ,B (7, 2) , C(6, −3) , and D(−4, −1) .
In rectangle opposite sides are equal.
Thus
AB = DC
AD = BC
Formula
Now the points A(−3, 4) and B(7, 2)
Thus
Now the points
A (−3, 4) , D (−4, −1)
Thus
Formula
Perimeter of rectangle = 2 (Length + Breadth)
Here
Perimeter of a rectangle = 30.6 units.
Therefore the perimeter of a rectangle is 30.6 units.
For this case we will first look for the total cost of the purse.
We then have the following rule of three:
14.95 $ -----> 100%
x -------------> 105%
Clearing x we have:
x = (105/100) * (14.95)
x = 15.6975 $
The amount needed to buy the purse is:
15.6975 - 10 = 5.6975 $
Answer:
holley needs 5.6975 $ to buy the purse
