18 students are 100%-37,5%-40%=22,5%
18 students - 22,5%
x students - 100%
22,5x=18×100
x=80
Answer: 80 students
I hope I wrote the question rightly
Answer: 18 people per minute
Step-by-step explanation: 162 divide by 9 equals 18
-6x + 12
To find this answer, follow these steps:
First, multiply 2x + 3 and x - 6 using either the FOIL method or the box method. This should get you the answer of 2x^2 - 9x - 18
This should now replace the 2x + 3 and x - 6
So with that, you should have this currently:
2x^2 - 9x - 18 - 2x^2 + 3x + 30
Now, combine like terms:
The 2x^2 cancels each other out. After that, combine -9x and 3x to get -6x. Then -18 and 30.
This should leave you with the final answer of -6x + 12
Hope this helps!
Answer:
x=y+9
Step-by-step explanation:
so what we do here is take x-9 and add 9 to both sides giving us y+9=x all we do is put x first and y+9 last and we have the inverse
