Ineed to find out what p is:
7.50=(0.12p)3

First you would deal with parentheses by multiplying three to (0.12p). Your new equation would be 7.50=0.36p. Then, you divide both sides of the equation by 0.36, so that you can get your variable alone. The answer will be p=20.8333 or whatever you round it to, such as 20.8 or 21.

What are the options

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
