Answer:
23 students
Step-by-step explanation:
We assume the wording "when 5 rows of seats are filled, 2 seats remain empty" means that there are 2 empty seats in the 5th row (which then would <u>not</u> be filled).
If n is the number of seats in a row, we think the problem statement means ...
5n -2 = 4n +3
n = 5 . . . . . . . . . . add 2-4n
Then 5(5)-2 = 23 = 4(5) +3.
There are 23 students in the class.
Answer:
28
Step-by-step explanation:
Ratios are like fractions. Since you're finding an equivalent ratio, u can set them up like equivalent fractions and put an x where the missing number would go:
You can either cross multiply and then solve for x, but it's easier to just think about it. The fractions are equivalent, right? So for them to be the same you'd have to do to the bottom what u do to the top.
To get from 1 to 4, you multiply by 4. By that logic, to get from 7 to x you'd have to multiply by 4 as well. Therefore x = 7x4, which is 28.
So x = 28
