Someone please help me with this question :) !

Collin did the work to see if 10 is a solution to the equation r/4=2.4

Agroup of three friends order a combo meal which includes two slices of pizza and a drink each drink is priced at $2.50 the combined total of $31.50 how much is the cost of a slice of pizza

Use a transformation to solve the equation. w/4 = 8 can you also leave a detailed explanation on how this equation = 32
