Answer:
40%
Step-by-step explanation:
If there are 1200 students in the school and 720 of them are boys that means 480 of them are girls.
I like to do cross multiply and divide so the equation for that would be 480/120 = ?/100
if you cross and multiply 480 by 100 you will get 48000 then if you divide that by 1200 you will get 40 as your missing value.
Im basically just saying 480/1200 = 40%
If you need further help there are plenty of you tube videos on how to cross multiply and divide
Hope this helps

Answer:
2y+1+9x is written as a product of three factors
If you want to find out what that number is, then let's call it n
n + 3n (Three times the number) + 12 = 32
Simplify
4n + 12 = 32
Subtract 12 from each side
4n = 20
Divide each side by 4
n = 5

Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:

As you can see, x increases in steps of 1 units. So let's check the difference in y:

So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:

Then:

Finally, the equation of the line is:
