Answer:
The probability that you will have $35 after your bet is 0.5263
Step-by-step explanation:
Consider the provided information.
If you bet $1 on each of 20 different numbers on one single spin of the wheel, what is the probability that you will have $35 after your bet.
If you bet $1 on a single number then the probability of winning is:

But if you bet $1 on each of 20 different number then the probability increases.
Thus the required probability is: 
Hence, the probability that you will have $35 after your bet is 0.5263

The solution is r= 7/a-x How did i do this?
Your equation is ax+ r=7, so the goal is to isolate the r. You begin by dividing the a from the ax. Remember, what you do to one side, you must do to the other. So you do 7/a, since you can't simplify 7/a, leave it as it is. Next, your equation should look like this x+r=7/a. In order to isolate the r, you move the x to the other side by subtracting, which leaves you with the answer of r= 7/a-x.

-17, I think.
12 - -5 = -17
17/1 =-17
X=-17
