Your answer is going to be A
Y=25*3^x
1170=25*3^x
25*3^x=1170
3^x=1170/25
3^x=46.8
Log10(3^x)=LOg10(46.8)
x*log10(3)=log10(46.8)
x=(log10/46.8))/(log10(3))
x=1.60724585307/0.47712125472
x=3.50067375233
x=3.50
Ratio is: 8:7
Because there are 8 girls against 7 boys

K/5 + 3 - 3k = -6k
Steps
Subtract 3 from both sides
k/5 + 3 - 3k - 3 = -6k - 3
Then simplify,
k/5 - 3k = -6k - 3
Add 6k to both sides
k/5 - 3k + 6k = -6k - 3 + 6k
Simplify,
k/5 + 3k = -3
Next, multiply both sides by 5
k/5 * 5 + 3k * 5 = -3 * 5
So,
k + 15k = -15
16k = -15
Then, divide both sides by 16
16k/16 = -15/16
Simplify,
k = -15/16
