Answer:
92
Step-by-step explanation:
LCM = 96
12 = 4×3
32 = 4 × 8
then GCF = 4
LCM - GCF = 96 - 4 = 92
for evey 1 part of water there is 3 parts juice so if there's only 1 part jucie it would be a 1/3
Answer:
![f(t)=20000(0.85)^t](https://tex.z-dn.net/?f=f%28t%29%3D20000%280.85%29%5Et)
Step-by-step explanation:
So the initial value of the business computer is $20,000. It depreciates by 15% per year. This is exponential decay. The standard function for exponential decay is:
![f(t)=P(r)^t](https://tex.z-dn.net/?f=f%28t%29%3DP%28r%29%5Et)
Where <em>P </em>is the initial value, <em>r</em> is the rate of decay, and <em>t</em> is the time in years.
Since the computer decreases by 15% per year, this means that each year, the computer will be 1-15% or 85% than its previous value.
Therefore, the equation that models the value of the computer is:
![f(t)=20000(0.85)^t](https://tex.z-dn.net/?f=f%28t%29%3D20000%280.85%29%5Et)
Start by solving for x in the first problem:
3x=3+9y
x=1+3y
Then plug that into the second equation:
6(1+3y)-3y=-24
6+18y-3y=-24
15y=-30
y=-2
Then plug that back into first equation:
3x-9(-2)=3
3x+18=3
3x=-15
x=-5
Then I would check your answer by plugging those into both equations:
3(-5)-9(-2)=3
-15+18=3
3=3 CHECK
6(-5)-3(-2)=-24
-30+6=-24
-24=-24 CHECK
So the answer is x=-5 y=-2
I think it would be 75 cookies because to get to 1 to 25 you multiply by 25, so you multiply 3 by 25 to get 75.
