Mixture A has 3 parts concentrate for 5 parts of water. Mixture B has 4 parts concentrate for 5 parts water.

So, for every 3 parts of concentrate you add 5 parts water or 3:5 for mixture A. Mixture B's ratio would be 4:5

Notice that Mixture B would be stronger because you are adding more concentrate to the same amount of water.

There could be many reasons.

Check for any missing or additional parentheses.

Use * for multiplying and ^ for exponents.

For this, all you have to do is multiply the 3 to each individual term:

3*x = 3x

3*6x = 18x

3*-3x = -9x

3*-3x = -9x

Now, add up all the terms:

3x + 18x - 9x - 9x

It is easy to notice that we cancel out 18x with -9x - 9x since 18x - 18x = 0, leaving us with 3x.

3x is the final answer.

c = 2pir

All you have to do is divide both sides by 2pi to get r by itself:

c/2pi = r.

r = c / 2pi.

4.5 is the same as 45/10 so if we split 4.5/45 into two fractions:

45/10 * 1 / 45

45/450

Divide both the top and bottom by 45:

1 / 10.

Note, the factors for 15 and 9 are:

15: 1, 3, 5, 15

9: 1, 3, 9

The greatest common factor is 3, so we divide both the numerator and denominator of 15/9 by 3:

15/3 = 5

9/3 = 3

We end up with 5/3.

To start, distribute the -6 by multiplying -6 with both the x and 2.

-6*x + -6*2 = -6x - 12.

Now, we have 5x - 6x - 12 = -3.

Collect "like" terms:

5x - 6x = -x

-x - 12 = -3.

Add x to both sides and add 3 to both sides:

-9 = x

x = -9.

We have to first distribute the 4. This means that we multiply 4 to each individual term in the parentheses and we keep the + sign.

So, it is like this:

4(x+2) = 4*x + 4*2 = 4x + 8.

Now, we have 4x + 8 = 6 + 4b.

Uh oh, we have two variables -- x & b. We cannot really do anything else to solve this equation!

All you have to do is divide the U.S. public debt by the population to get the average U.S. public debt per American.

9.06*10^12 divided by 3.08*10^8 = ?.

So, we know the cost should be greater than $35 since we have to add the sales tax.

10% is the same as 10/100 which means you just have to move the decimal place two times to the left: 10% --> 0.1

Now, $35*0.1 = $3.5

Finally, we have to add the original cost + the sales tax cost:

$35 + 3.5 = $38.50.
