Thanks CPhill! :)

2/3 ÷ 1/6

Multiply 2/3 by 2 over 2 to get a common denominator

4/6 ÷ 1/6

Use the reciprocole

4/6 x 6/1

Multiply across

24/6

Simplify

4

There's the first problem, and hopefully it will help you in figuring out the second :) If you need more help just ask

Here's a few I found:

- If the bases of the exponential expressions that are multiplied are the same, then you can combine them into one expression by adding the exponents.

- If the bases of the exponential expressions that are divided are the same, then you can combine them into one expression by subtracting the exponents.

- When you have an exponential expression raised to a power, you have to multiply the two exponents.

- Any number or variable raised to the zero power is always equal to 1.

Hopefully this helps a bit :)

1 + 1 ÷ 600(2)

Simplify

2 ÷ 1200

Divide

0.00166666666

If you're talking about on this site, people try to respond as fast as they can, but depending on who is online, whether registered users or guests, it depends on their skill set and whether they know how to answer your question(s) :)

2 + 2 = 4

Next time use a calculator, such as the one found on the home page of this site :)

You need to figure out how much 10.1% interest is, by multiplying 10.1 by 8700

Then, since you're trying to find out how large your account balance will be in years and that interest is monthly, you multiply the interest by 12 and then add that on to 8700

After that, you add up the number you got above, 33 times for the 33 years,

Hopefully this helps! :) I appologize in advance if this in incorrect

This is off of Google since I'm not very good at explaining...

The substitution method is most useful for systems of 2 equations in 2 unknowns. The main idea here is that we solve one of the equations for one of the unknowns, and then substitute the result into the other equation. Step 1: Solve one of the equations for either x = or y = .

And this video from Khan Academy might be helpful too :)

3/4 ÷ 1/6

Use the reciprocal

3/4 x 6/1

Now multiply across

18/4

Simplify

4 2/4

Simplify again

4 1/2

And there's your answer :)

Okay thanks CPhill, I was so unsure of what I did for a while!
