Solve for x. Worth 20 pts.

You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7
