When the radius is doubled, the volume of a cylinder quadruple
<span>6x-7y=-84
7y = 6x + 84
y = 6/7(x) + 12</span>
Answer:
Da answer issss...7.4 x 10^4..I tink
F=m+25
m+f=139, using f from above we have:
m+(m+25)=139
2m+25=139
2m=114
m=57, and since f=m+25
f=82
So there are 57 males and 82 females.
