I need help with this question I wasn’t sure on what to pick as the answer.

Answer: 7 5/7 (the bottom one)

Step-by-step explanation:

30 divided by 2 = 15 (do the same to 42 and get 21)

This then creates the fraction: 15/21

Now, divide this fraction by 3 and get 5/7

Add back in the seven because you aren't dividing the whole number.

Your final answer is now 7 and 5/7 (together: 7 5/7)

In a large apartment building, 35 of the apartments have a balcony and 55 do not.
Masteriza [31]
Hello!

You first have to find the total amount of apartments

35 + 55 = 90

There are 90 apartments

Then you find the percentage of them have a balcony

You do this by taking the amount of apartments that have a balcony over the total amount of apartments

35/90 = 0.39

0.39 as a percent is 39%

The answer is 39/100 or 39%

Hope this helps!

[Ignore the 2 problems] I need help on #9

Let's use (a) as an example. What number is in front of the x inside be brackets? If I gave you the choice of 1,2,3,4,5 which number is it out of those 5?

If you chose 5, you have the second best answer. You are reading outside the brackets. Not what we need.

If you choose 1, you are well on your way. There is a 1 beside the x.

Now go to the outside of the brackets. What's in front of the x? 1,2,3,4,5.. There is only one number you can choose. It's a 5. So the result outside the brackets is 5x. How did 1x become 5x? You had to put a 5 on the blank to the left of the brackets..

5(5 + x) = 5x + ___ What goes on the line to the right of 5x? Rule whatever you do to one side of a plus sign inside the brackets, you must do to the other side of the plus sign.

It becomes 5*5

So the blank is filled with 25. And here's the answer.
5(5 + x) = 5x + 25 <<<< answer..
Stop don't do anything more. 5x and 25 are not like terms. They don't mix

9B
Let's make this one brief so that you have something to do. What did you multiply 5 by to get 10? You should answer 2.
2(x + 5) = ___ x + 10

What you do on one side of the plus sign, you must do on the other. So what's in front of the x on the right?

2(x + 5) = 2x + 10 <<<< answer
