So
x- quarters
y - dimes
z- nickels
The system of equations would be
x+10=y
z+5=x
x+y+z= 4.75
Answer:
Final answer is approx x=0.16.
Step-by-step explanation:
Given equation is 
Now we need to solve equation
and round to the nearest hundredth.











Round to the nearest hundredth.
Hence final answer is approx x=0.16.
Answer: g(x) decreases by 7
Step-by-step explanation:
Simple algebra and substitution of variables for the number can help you to solve the problem,
g(7)=50-2(7)
g(7)=50-14
g(7)=36
I hope this helps
The answer is 4.5 l
To calculate this, we will use the Boyle's law using constant k, pressure P, and volume V:
PV = k
We can forget temperature since it is constant.
We have:
P1V1 = k
P2V2 = k
So, P1V1 = P2V2
P1 = 3 atm
V1 = 1.5 l
P2 = 1 atm
V2 = ?
_____
P1V1 = P2V2
3 atm * 1.5 l = 1 atm * V2
4.5 atm/l = 1 atm * V2
V2 = 4.5 atm l / 1 atm
V2 = 4.5 l
Answer:
The system has one solution.
Step-by-step explanation:
We have two equations:
y = -2x - 4
y = 3x + 3
Equalling them:
y = y
-2x - 4 = 3x + 3
5x = -7

And

Replacing in the other equation we should get the same result.

So the system has one solution.
