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:
You would need to score a 93% to have an average of 90.
Step-by-step explanation:
Well, to check my work you would need to find the average.
So, 93 + 92 + 88 + 87 = 360. Then you divide by four; 360 / 4 = 90. ^^
Step-by-step explanation:
n/12=10
n=10*12
n=120
