Solution

In order to find greatest to least number, we have to convert the given fractions into decimals.

3 $\frac{1}{10}$ % = 3 + 1/10 = 3 + 0.10 = 3.10%

3 $\frac{2}{5}$ % = 3 + 2/5 = 3 + 0.40 = 3.40%

3 $\frac{1}{4}$ %= 3 + 0.25 = 3.25%

3 $\frac{1}{3}$ % = 3 + 0.33 = 3.33%

Now we can easily, compare the numbers and write from greatest to least.

3.40%, 3.33%, 3.25%, 3.10%

Greatest to least = 3 2/5%, 3 1/3%3, 3 1/4%, 1/10%,

Thank you :)

With this, you need side A to equal side B. Your first step is to move the variable to one side. (I've also worked in out, and color coordinated the steps, so you can see better).

11 + 4b = 8b - 13 < let's subtract "4b" from the left side to get rid of it (we're subtracting because it is added on to left side). This will give us:

11 = 8b - 13 < we've subtracted "4b" from the left side, however what you do to one side of the equal sign, you must do to the other, so subtract "4b" from the right side as well. Once done, you should have this"

11 = 4b - 13 < we have "4b-13" because you can only work with like terms. 8b-4b=4b, and the 13 stays untouched.

Now let's work on isolating the variable. See how we have a -13 on the side with the variable? We don't want that, so we're going to add 13 to that side, to give us 0 and cancel it out. Remember, what you do to one side, you must do to the other, so add 13 to the 11 on the other side as well. This will give you 24, and your equation should now look like this:

24 = 4b < we're almost done, but the variable is not quite by itself yet. We need to get rid of the "4" in "4b". 4 in being multiplied to "b" so we need to do the opposite operation to cancel it out. We need that 4 to be a 1 because 1x=x. So, divide 4b by 4 to get 1b or just plain b.

Remember, what you do to one side, you must do to the other, so divide 24 by 4 to get 6, and you're left with your answer.

Answer 6 = b

Hope this helps!

On a huge site in San-Diego the whole new street of houses was constructed. To put the numbers on all new buildings the plates w

<h2>There are 45 houses on the left and require 95 plates, while there are 44 houses on the right and require 94 plates</h2>

Step-by-step explanation:

Houses are numbered from 1 to 99. So, there are 99 houses. Odd-numbered houses are on the left. So, there are 50 houses on the left, while there are 49 houses on the right.

For houses on left : The houses are numbered 1, 3, 5, 7, 9, 11, 13..... 97, 99

So 5 houses( 1, 3, 5, 7, 9) require only one plate for numbering, while the remaining 45 houses require 2 plates each. So total number of plates = $5\textrm{x}1+45\textrm{x}2$ = $95$ plates.

For houses on right : The houses are numbered 2, 4, 6, 8, 10, 12, 14.... 96, 98

So 4 houses( 2, 4, 6, 8) require only one plate for numbering, while the remaining 45 houses require 2 plates each. So total number of plates = $4\textrm{x}1+45\textrm{x}2$ = $94$ plates.
