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
![c^2 - 9c = 22\\\\c^2 - 9c - 22 = 0\\\\c^2 - 11c + 2c - 22 = 0\\\\c(c - 11) + 2(c - 11) = 0\\\\(c + 2) (c - 11) = 0\\\\=> c = -2, c = 11](https://tex.z-dn.net/?f=c%5E2%20-%209c%20%3D%2022%5C%5C%5C%5Cc%5E2%20-%209c%20-%2022%20%3D%200%5C%5C%5C%5Cc%5E2%20-%2011c%20%2B%202c%20-%2022%20%3D%200%5C%5C%5C%5Cc%28c%20-%2011%29%20%2B%202%28c%20-%2011%29%20%3D%200%5C%5C%5C%5C%28c%20%2B%202%29%20%28c%20-%2011%29%20%3D%200%5C%5C%5C%5C%3D%3E%20c%20%3D%20-2%2C%20c%20%3D%2011)
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:
There are no real solutions to this equation
Step-by-step explanation:
If 28% is 42 people
you have to get from 28 to 100 by timsing 28 by '?'
100/28 =<span>3.57142857143
</span><span>3.57142857143 x42=150 people</span>
It depends if 5x-3 means (5x)-3 or 5 times -3
if it is (5x)-3 then go to AAAAAAAAAA
if it is 5 times -3 then go to BBBBBBBB
AAAAAAAA
PEMDAS
parenthaee first
32 times 50=1600
nowe we have
5x-3+1600
add like terms
5x+1597 (we can't add placeholders and constants)
BBBBBBBBBBB
PEMDAS
parenthaee first
32 times 50=1600
nowe we have
5x-3+1600
5 times -3=-15
now we have
-15+1600
add
1585
if 5x-3=(5x)-3 then the answer is 5x+1597
if 5x-3=5 times -3 then the answer is 1585
