Answer: x > 5
Explanation: First we want to look at our variable and ask ourselves what's happening to it. Since 2 is being subtracted from 9x, we always undo addition and subtraction first so we add 2 to both sides.
That gives us 9x > 45.
Now we need to undo multiplication and division. Since 9 is being multiplied by <em>x</em>, to get <em>x</em> by itself, we need to divide by 9 on the left side of the inequality. If we divide by 9 on the left side, we must also divide by 9 on the right side.
This leaves us with <em>x > 5</em> which is the solution to this inequality.

Step-by-step explanation:
Let's solve for a.
ax+3=6
Step 1: Add -3 to both sides.
ax+3+−3=6+−3
ax=3
Step 2: Divide both sides by x.
ax
/x
=

Answer:
3 hours
Step-by-step explanation:
We can solve using ratios
18 lbs 12 lbs
------------ = --------------
4.5 hrs x hours
Using cross products
18x = 12 * 4.5
18x = 54
Divide by 18
18x/18 = 54/18
x=3
Answer:
to do this question, add width + height. 4/6 + 2/5 are not normally add-able. So to correct this, we find the most common factors. There is 1, 5, and 6 at highest. 5 and 6 share a high number multiple if you combine them. This multiple is 30. So now, keep, change, flip.
4x2 is 8.
6x5 is 30.
I would say the answer should be eight thirtieths.
