Answer:
0, -2, 2, -1
Step-by-step explanation:
You are trying to make it so that the one of the ( )= 0.
An example is (x+15) or (2x+3)
the first l one would be x= -15 since -15+15 would equal 0.
The second one is -3/2 since it would be -3+3 which would equal 0.
also since the equation starts with x( or -x it doesn't really matter) one of the zeros would also be 0.
Hope this helps!
Answer:
Expanded form of
= 3000 + 180 + 12
Step-by-step explanation:
Expanded form of any number is important in math as it allows us to look at a number and identify the value of each digit.
We can write a whole number 532 in a expanded form as:
![532 = 500 + 30+2](https://tex.z-dn.net/?f=532%20%3D%20500%20%2B%2030%2B2)
![6 \times 532 = 6 \times (500+30 + 2)](https://tex.z-dn.net/?f=6%20%5Ctimes%20532%20%3D%206%20%5Ctimes%20%28500%2B30%20%2B%202%29)
= ![3000 + 180 + 12](https://tex.z-dn.net/?f=3000%20%2B%20180%20%2B%2012)
Therefore, the expanded form of
is, 3000 + 180 + 12
Answer:
D. He should add between 2 cups and 3 cups of dirt.
Step-by-step explanation:
First we need to take the ratio of dirt to peat moss.
8 parts dirt : 3 parts peat moss.
Now we take the ratio and find the value of dirt.
8 : 3 = ![\dfrac{8}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B8%7D%7B3%7D)
x : 1 = ![\dfrac{x}{1}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B1%7D)
![\dfrac{x}{1} = \dfrac{8}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B1%7D%20%3D%20%5Cdfrac%7B8%7D%7B3%7D)
We now multiply both sides by 1.
![1\dfrac{x}{1} = 1\dfrac{8}{3}](https://tex.z-dn.net/?f=1%5Cdfrac%7Bx%7D%7B1%7D%20%3D%201%5Cdfrac%7B8%7D%7B3%7D)
![x = \dfrac{8}{3}](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B8%7D%7B3%7D)
![x = 2.67](https://tex.z-dn.net/?f=x%20%3D%202.67)
So now we substitute x.
2.67 Cups Dirt : 1 Cup Peat Moss
