Answer:
infinite solutions
Step-by-step explanation:
distribute--- 5x-15+6=5x-9
simplify--- 5x-9=5x-9
An average is just the total attendance numbers / the number of performances.
Let's let the number of people in the third show be equal to x so we can write this as a formula, it's easier to read. x is just "some number we don't know"
The average is
Average=Total attendance/3
So
3000=(2580+2920+x)/3
So let's multiply by that 3 on both sides, make x easier to find
Average*3=2580+2920+x ( * means multiplied)
The average is 3000
So
2580+2920+x=3000*3
2580+2920+x=9000
Then we subtract those other attendances to get x on its own.
x=9000-2580-2920
x=3500
Answer:
he would need to play at least five rounds
Step-by-step explanation:
1 bag with 48 candies, 2 with 24 candies, 3 with 16 candies, 4 with 12 candies, 6 with 8 candies, 8 bags with 6 candies, 12 with 4, 16 with 3 each, 24 with 2, and 48 with 1
(x,y) = (1, 1.2)
1 = 7(1) - 5(1.2)
1 = 7 - 6
There are many other options though.
