Answer:
2 bags
Step-by-step explanation:
Let the number of bags be b.
Let the number of candies in each bag be c.
The number of bags was 9 less than the number of candies in each bag. That is:
b = c - 9
She bought 22 candies.
This means that The number of candy in each bag multiplied by the numbe of each bag is 22:
b * c = 22
bc = 22
=> (c - 9) * c = 22
Since the number of candies can only be a positive number, c = 11.
Therefore:
b = 11 - 9
b = 2
Katy bought 2 bags of candy containing 11 candies each.
Answer: 35 more times
How: (if she gets 60 points for each grocery store visit then first do 2580-480=2100. she still needs 2100 points so then 2100/60 = 35 grocery visits!)
For this equation you will have to substitute the y for (-x)
Therefore,
-x=3x-4
-x-3x=-4
-4x=-4
-4x/-4=-4/-4
X= 1
