Answer:
2q + 11
Step-by-step explanation:
Add like terms.
2q + 2 + 9
2 and 9 are like terms because they don't have letters like 2q.
2q + (2 + 9)
2q + 11
Hi!
Let's find the square root of 9/36.
First, find the square root of 9.
To do that, factorize it.
9/3 = 3
3/3 = 1
3 * 3 = 9
The square root of 9 is 3.
Now find the square root of 36.
36/2 = 18
18/2 = 9
9/3 = 3
3/3 = 1
2 * 2 * 3 * 3 = 36
You could also write this as...
2 * 3 * 2 * 3 = 36
Solve part of it and you get...
6 * 6 = 36
The square root of 36 is 6.
The answer is 3/6, but simplified it's 1/2.
Hope this helps! :)

Step-by-step explanation:
-3 +2 +-1 +-2 +-3 +1 = -6 yards total
-6 / 6 = -1 yard per play average
You will need 252 mL of pure water to obtain 0.25 mL of the desired 25% solution.
If we add X amount of water to the solution, the total amount of solution is 375+X.
And that must be 25%.
<h3>
What is the amount of solute in the current solution?</h3>
The amount of solute in the current amount of solution is
0.6(375)=225.
That amount won't change by adding water.
So we set up the equation so that the amount of solute divided by the new total amount of solution equals 25%.
225/(375+X)=0.25
cross multiply and solve
225/0.25=(375+X)
900-375=X
X=525
The pure water will you need to add to obtain the desired solution is 525.
Then we check 225/(375+525)=0.25.
