900% of 450=4050
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 450 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 450 is 100%, so we can write it down as 450=100%.
4. We know, that x is 900% of the output value, so we can write it down as x=900%.
5. Now we have two simple equations:
1) 450=100%
2) x=900%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
450/x=100%/900%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 900% of 450
450/x=100/900
(450/x)*x=(100/900)*x - we multiply both sides of the equation by x
450=0.111111111111*x - we divide both sides of the equation by (0.111111111111) to get x
450/0.111111111111=x
4050=x

Answer:
D: (1, 4)
Step-by-step explanation:
You can either solve by substitution or elimination. If you are timed, the fastest way is to guess and check (plug-in the answer choices)
I will be using substitution to solve this:
Step 1: Since you have y already, you can set them equal to each other
x+3 = 3x+1
3 = 2x +1
2 = 2x
x = 1
Step 2: Now you have x, plug x into one of the original equations. In this case, I will use the first one
y = 1 + 3
y = 4
Step 3: Now write your answer as a coordinate plane point
x = 1, y = 4
