The next step of your proof is to subtract (a/b) from both sides.
Then you get, x = (m/n) - (a/b)
Since rationals are closed over addition, (m/n) + (-a/b) is a rational number.
Therefore, x (an irrational number) = a rational number <em>This is a false statement which is a contradiction. So, the assumption was incorrect.</em>
Thus, the sum of a rational and irrational number is an irrational number. QED

Answer:
143
Step-by-step explanation:
450-28= 422
422÷2.95= 143.05
round down to 143
Written explanation:
If her first card had $450 but she spent $28 that means she only has $422 left. In order to find out how many barrettes she can buy you divide the amount she has left by 2.95 and get roughly 143.05 barrettes, but you can't go over the budget so at the max Erin can only get 143 barrettes
