Determine the inequality
Assume she wants to buy n CDs.
If 1 CD costs $10, then n CDs costs 10n.
So, the inequality is:

<em>We used </em>
<em> because the amount she wants to spend cannot exceed 30</em>
Divide both sides by 10, to solve for n

Answer:B *54 degrees*
Step-by-step explanation:
2x-10 + 1/2x + 20 = 180
add up like terms
2.5x + 10 = 180
subtract 10 from both sides
2.5x = 170
divide by 2.5 on both sides
x = 68
now plug in x to the (2x-10) expression [which will get you 126 degrees]
then subtract 180 - 126 to fine angle y. which should get you *54 degrees*
5/7 - 1/5 =
25/35 - 7/35 =
18/35
