Three-fourths of the students in the class did their homework last night. if 18 students in the class did their homework,
how many students are there in the class? write an equation for this situation. solve your equation algebraically two different ways.

24 people are in the class

I am sorry I don’t know the equation but I hope this helps.

Step-by-step explanation:

3. 18. 18

- =. —. =. —-

4. ? 24

`1234567890-=/*-qwertyuiop[]asdfghjkl; '\\zxcvbnm,./+ /

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!
