Ms. Hampton's sixth grade class is going on a field trip to the art museum. The museum requires
students to tour in groups of three. If there are 24 students in Ms. Hampton's class, how many
different combinations of three-student groups are possible?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

The second and fourth answer are correct

A: 18/15b : 7 - -8 = 15 , 12 - -6 = 18 the y variable always goes over the x variables, c : same thing a
