Billy is buying soda for a class party. He needs five 2-liter bottles. If three 2-liter bottles cost $7.00, how much will five cost?

$11.66

Step-by-step explanation:

3 bottles cost 7.00 so make a ratio 3/7

5 bottles costs ? so turn that into a ratio 5/?

3/7=5/? cross multiply

3?=35

35/3=$11.66

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
