Michael bought 7 pizzas from Pizza by Alfredo and 9 pizzas from Alfredo's Pizza Cafe.
Step-by-step explanation:
Cost of Pizza at Pizza by Alfredo = $3
Cost of pizza at Alfredo's pizza cafe = $5
Total amount spent = $66
Let,
Pizzas bought from Pizza by Alfredo = x
Pizzas bought from Alfredo's Pizza Cafe = y
According to given statement;
3x+5y=66 Eqn 1
5y = 3x+24 Eqn 2
Putting value of 5y from Eqn 2 in Eqn 1;
Dividing both sides by 6
Putting x=7 in Eqn 2
Dividing both sides by 5

Answer:
Step-by-step explanation:
(48-3x)>6x-8
48-3x>6x-8
Collecting like terms, we have
-3x-6x>-8-48
Moving variables or numbers from one side to the other changes the sign it carries
-9x>-56
Divining both sides by -9 changes the inequality sign
x<56/9
x<6.22
