performance show. How many students should
be lined up in each row?

56 students per row

Step-by-step explanation:

15 students should be lined up in each row.

Step-by-step explanation:

A group of 225 student needs to be arranged in a square formation.

This means same number of students will sit in each row as in each column.

To find this we will take the square root of 225.

There will be =  students in each rows and columns.

Therefore, 15 students should be lined up in each row.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
