On Saturday, a local hamburger shop sold a combined total of 480 hamburgers and cheeseburgers. The number of cheeseburgers sold was three time the number of hamburgers sold. How many hamburgers were sold on Saturday?

160

Step-by-step explanation:

If you divide 480 by three, you get 160. If you multiply 160 by 3 (that's the part where they sold 3x as much cheeseburgers) then you get 480.

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
