On school trip ,the students are spilt into equal groups. there are 18 students in 3 groups.
how many groups are needs if there are 54 students?

Find the greatest common factor of -30x 4 yz 3 and 75x 4 z 2.

Solve 3x-18=2y and 5x-6y=14 by elimination or substitution . show all !

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
