9x-30 I’m pretty sure!
We are finding the difference, which means subtract! Nine times a number would be 9x and since it’s difference you would subtract it by 30.
1/4 exact form, 0.25 decimal form.
Answer:
C
Step-by-step explanation:
2x + 1 = 85 (Alternate Interior Angles Theorem)
2x = 84
<em>x = 42</em>
(3y + 5) + (2x + 1) = 180 (Linear Pair Theorem)
3y + 5 + (85) = 180
3y + 5 = 95
3y = 90
<em>y = 30</em>
Since you can 4 pieces from 1 foot, you multiply 4 by 5 and you get 20 pieces.
