Answer:
x = 5
Step-by-step explanation:
First, we move all variables to one side of the equation. (Don't forget to change signs.)
9x - 8x + x = 7 + 3
Then, we simplify
x + x = 10
2x = 10
10 divided by 2 is equal to 5.
Therefore, x = 5

A ratio shows us the number of times a number contains another number. The amount barely needed for 300 ml of milk is 45 grams.
<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
The need for barley in 200 ml of milk is 30 grams, therefore, the need for barley in 1 ml of milk can be written as,
Need of barely in 1 ml of milk = 30/200
Now, the amount of barely that will be needed for 300 ml of milk will be,
The amount of barely in 300 ml of milk = (30/200)×300 = 45 grams.
Hence, the amount barely needed for 300 ml of milk is 45 grams.

So there are 10 offices in the first 2 floors
All the stories of the building have the same amount of offices on each floor
to see how many are on one floor
10 / 2
That is there are 5 offices on each floor
If there are 5 floors
then... 5+5+5+5+5
or 5*5
There are a total of 25 rooms in a 5-story building.
