That the equation could be combined into like terms
Answer: Mary has 16 video games.
Step-by-step explanation:
x+(x+2) =30
2x + 2 =30
-2 -2
2x =28
x= 14
(14+ 2) = 16

bearing in mind, "t" is in years, 6months is just 1/2 year
solve for "r", you'd get a decimal amount, multiply times 100, to get the percentage form
