Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160
Answer:
27
Step-by-step explanation:
r = 2 cm, h = 6 cm.
V = r² π h = 2² · 3.14 · 6 = 4 · 3.14 · 6 = 75.36 cm³
2000 : 75.36 = 26.54

Answer:
your answer is for sure D but I think C is also the answer
Step-by-step explanation:
