F(g(x)) = f(4/x) = (4/x)/(4/x - 7) = (4/x)/((4 - 7x)/x) = 4/x * x/(4 - 7x) = 4/(4 - 7x)
Answer:
The amount of water must be added to this task = 60 
Step-by-step explanation:
Let amount of water added = x 
Then from the given conditions
A chemist would like to dilute a 90-cc solution that is 5% acid to one that is 3% acid. So
90 (0.05) = 0.03 ( 90 + x )
4.5 = 2.7 + 0.03 x
0.03 x = 1.8
x = 60 
Therefore the amount of water must be added to this task = 60 
Answer:
120kmph
Step-by-step explanation:
480%4=120
X=1st con odd #
x+2=2nd con odd #
x+4= 3rd con odd #
x+6= 4th con odd #
x+8= 5th con odd #
x+10= 6th con odd #
x+12= 7th con odd #
x+x+2+x+4+x+6+x+8+x+10+x+12=525
7x+42=525
7x+42-42=525-42
7x=483
7×/7=483/7
x=69
69+12=81
81 is the answer :)
