Need help ASAP will give if correct

0.80c + 12 ≤ 28.40

c ≤ 20.5

Step-by-step explanation:

c represents # of cups of coffee

0.80 is the price per cup of coffee

so in the inequality it's 0.80c

$12 is how much the mug costs so it's + 12

for solving the inequality isolate c :

0.80c + 12 ≤ 28.40

0.80c ≤ 16.4

c ≤ 20.5

so this means that charlie can buy 20.5 cups of coffee and a $12 mug and the total won't exceed the $$$ on his coffee stop card

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

maybe showing the graph would
