Answer:
∠8 * 4 = ∠7 ----------------(1)
∠8 + ∠7 = 180 ------------(2)
Taking the value of ∠7 from (1) and using it in (2):
<u><em>∠7 = 4 * ∠8</em></u>
<u><em /></u>
∠8 + ∠7 = 180
∠8 + (4 * ∠8) = 180
∠8 + 4∠8 = 180
5∠8 = 180
∠8 = 36° ---------------(3)
Using the value of ∠8 from (3) in (2):
∠8 + ∠7 = 180
36 + ∠7 = 180
∠7 = 144° and ∠8 = 36°
The correct answer I got was 22 cups. 11/2 ÷ 1/4 is how you set it up. Then, you do KCF which stands for keep, change, flip. So, your new expression is 11/2 × 4/1. You cross reduce 4 & 2 which makes the new expression 11/1 × 2/1. 11 times 2 is 22/1 which still equals 22.
.8, 1.8, 8, 8.1
Do you understand why? This seems pretty simple that you should be able to solve this for yourself.
All you have to do is add exponents when multiplying like monomials. So it's just 4^2
