20 points ill give brainlest if u can answer both !!

3)

Each stripe is 1/18 yards thick, and the fence post if 5/6 yards. Therefore, we have to find how many 1/18s can go into 5/6. Thus, this is a matter of division, and we do 5/6 divided by 1/18 to find how many stripes we can have.

5/6 ÷ 1/18 = 5/6 * 18 = 15

Thus, the answer is D.

4) A is 3, which means we substitute all the "a"s in the expression for 3. Thus we have:

99 - 7

99 - 7(3)^2

99 - 7(9)

99 - 63 = 36

Therefore, it is 36.

∠cbe and ∠deb are same-side interior angles.
