A student is told to work any 8 out of 10 questions on an exam. In how many different ways can he complete the exam

Answer:

?=8

Step-by-step explanation:

I substituted the ? for x

-3=x-11

first we want to isolate the x to do that, you have to find a way to move -11 to the other side. Well, x+0=x right? So all we have to do is find a way to go from -11 to 0! In this case you add 11 to both sides. This is very important so don't forget.

-3=x-11

+11    +11

-3+11=8

x=8

If you check your work, this should also go back in perfectly.

-3=8-11

or

-3=-11+8

I hope this helps!

Have a good day!

Answer:

Credit cards typically have high interest rates compared to most other types of loans. That means it’s potentially expensive to borrow money with a credit card. When you don’t pay your full credit card balance every month, it’s easy to accumulate boatloads of interest fees quickly.

What is a credit card minimum payment? It’s the minimum amount of money a credit card company is willing to accept each month to keep your account in good standing.

Don’t make the mistake of thinking the minimum due is a “monthly payment” you should be making to pay off your credit card bill. When you only pay the minimum due on your credit card statement, your credit card issuer will make a lot of extra money from you.
