Answer. Number one i think.
13. Is 18
15. Is 86
17 is 5
19 is 15
21 is 24
23 is 29
That would be a scalene because none of the sides are congruent (the same size)
Since we know there are 3 quarts of pineapple juice and 2 gallons of orange juice the first thing you need to do is convert the units of the orange juice to quarts.
If there are 4 quarts in a gallon and we have 2 gallons then we have 8 quarts (4*2)
So 3 quarts of pineapple juice to 8 quarts of orange juice.
The ratio would be <u><em>3:8</em></u>
domain is {2.4, 4.8, 6.3, 8.8, 10.1 }
For domain, equate f(x) to each value in the range and solve for x
7x - 2.7 = 14.1 ⇒ x = 
= 2.4
7x - 2.7 = 30.9 ⇒ x = 
= 4.8
7x - 2.7 = 41.4 ⇒ x = 
= 6.3
7x - 2.7 = 58.9 ⇒ x = 
= 8.8
7x - 2.7 = 68 ⇒ x = 
= 10.1
