Astore has display will have six rows with 12 containers in each row if 39 containers has been set up so far explain how to find the number of containers that still need to be set up then solve the problem

Multiply the number of rows with container.
6×12= 72
39 containers have been already set, but there's 72 total.
Subtract the overall number of containers by the containers already set.
72-39=33

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!
