Question

Solve for x: x + 2 1/2 = 7. Also please EXPLAIN the work. I keep getting trouble on these problems.

Answer 1

is that 2 1/2 like 2.5 and not \(\large 2^{\frac{1}{2}} \)??

Answer 2

It's not the 2.5 part, I mean the mixed number part.

Answer 3

okay... mixed number.... i shuda said that....:)

Answer 4

subtract 2 1/2 from both sides to get:

x = 7 - 2 1/2
= 4 1/2

Answer 5

that mixed number is "four and one half."
