Howard Earned a total of 12$ by selling 8 cups of lemonade. How many ups of lemonade does Howard need to sell in all to earn 21$?

Step-by-step explanation:

(12 dollars)/(8 cups) = (12/8 dollars)/cup = (1.5 dollars)/cup

21 dollars × (1 cup)/(1.5 dollars) = 21/1.5 cups = 14 cups

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.
