Answer:
C. 25
Step-by-step explanation:
sister's cookies = 2.5* boy's cookies
sisters cookies = 2.5 * 10
sister's cookies = 25
Answer:
(x-2)²=9
sqrt both sides
don't forget positive and negative roots
x-2=+/-3
well, she is partially correct
x-2=3 is one answer
she didn't remember the other one the x-2=-3

Answer:
x = 25
Step-by-step explanation:
4x - 3(x + 5) = 10
4x - 3x - 15 = 10
4x - 3x = 10 + 15
x = 25
Answer: He can buy 12 shooters with $1. 20 red marbles with $1. 300 multicolored marbles.
Step-by-step explanation:
Shooters = 1 dollar is 60 cents
60 divided by 5 = 12
Red = 60 divided by 3
= 20
Multicolored = 60 x 5 because 1 for 5
= 300
P.S Not sure if my answer is correct.....
This is a problem that deals with exponential growth and the formula for exponential rate problems is:

, where a= principal amount, b = rate, and t = time.
Let's substitute the corresponding values into its appropriate places: the starting amount is $4,400, the rate is 0.065 but we need to add an 1 because it's an exponential growth problem so it would be 1.065, and the time is 3 years.
Now solve:
[tex]y = $4,400(1.065)^3[tex]
