make sure your calculator is in Degree mode.

Say r is rational. Suppose for a second, that s is not. Then, r+s is irrational. But this contradicts the fact that b is rational.
So, if one root is rational, then the other root is also rational

Answer:
$678.98
Step-by-step explanation:
Let the amount she had before she started spending be T. If she went shopping and spent $493.98 then the amount she would have is
= T - 493.98
Given that she has $185 left then
T - 493.98 = 185
Add 493.98 to both sides
T - 493.98 + 493.98 = 185 + 493.98
T = $678.98
She must have had $678.98 in her bank account to begin?
