Answer:
99
Step-by-step explanation:
That quadrilateral equals to 360. So i had to add the numbers which equal 261. Then i did 360-261=99.
6.11
see- .8 .9 .10 so its .11

How to Simplify a Ratio A : B when A and B are both whole numbers:
- List the factors of A
- List the factors of B
- Find the greatest common factor of A and B, GCF(A, B)
- Divide A and B each by the GCF
- Use the whole number results to rewrite the ratio in simplest form
Try to reduce the ratio further with the greatest common factor (GCF).
<em>The GCF of 14 and 4 is 2</em>
Divide both terms by the GCF, 2:
14 ÷ 2 = 7
4 ÷ 2 = 2
The ratio 14 : 4 can be reduced to lowest terms by dividing both terms by the GCF = 2 :
14 : 4 = 7 : 2
Therefore:
14 : 4 = 7 : 2
Part A) y = 2x
Part B) 10 packages because in 5 gallons of ice cream there’s 80 cups and if its only sold in packs of 8 you divide 80 by 8 and get 10
