900% of it is 450 ?<br><br> please help with this
charle [14.2K]
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

4x + 2y = 10 identify the slope and the y intercept ​
Alecsey [184]

Answer:

Slope in this case is -2

Y-Intercept in this case is 5, or (0, 5)

Step-by-step explanation:

In order to identify the slope and y-intercept, you must put the equation is y = mx + b form. This is quite simple! Don't panic! You got this :)

4x + 2y = 10

Move x to the right

2y = -4x + 10

Divide by y's coefficient

y = -2x + 5

Slope in this case is -2

Y-Intercept in this case is 5
