Answer:
30 tennis balls
Step-by-step explanation:
30 to 50 is equal to 3 to 5. And if there are 30 baseballs for every 50 tennis balls, and there are 80 balls in total, well...
30+50=80
So there are 30 tennis balls
Answer:
x = 3
y = 3/2
Step-by-step explanation:
look at the hangers to form an equation:
x + x + x + 3 + 3 + 3 = x + x + y + y + y + y
simplify
3x + 3 = 2x + 4y
x + 3 = 4y
x = 4y - 3
you also know that
x + x = y + y + y + y
2x = 4y
substitute x = 4y - 3 into this equation ^
2x = 4y
2(4y - 3) = 4y
8y - 6 = 4y
4y = 6
y = 6/4
y = 3/2
2x = 4y
2x = 12/2
2x = 6
x = 3
5! = 5 *4*3*2*1 = 120
2! = 2*1 = 2
120 +2 = 122
Number 1 is not equivalent to 2/3
