{From Unit 1. Lesson 13.) 7. Kiran's family is having people over to watch a football game. They plan to serve
sparkling water and pretzels. They are preparing 12 ounces of sparkling water and 3
ounces of pretzels per person. Including Kiran's family, there will be 10 people at the
gathering
A bottle of sparkling water contains 22 ounces and costs $1.50. A package of pretzels
contains 16 ounces and costs $2.99. Let n represent number of people watching the
football game, s represent the ounces of sparkling water, p represent the ounces of
pretzels, and b represent Kiran's budget in dollars. Which equation best represents
Kiran's budget?
A 12 + 3n-

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
