Answer:
72 boys=72:40
45 girls=81:45
90 girls=162:90
40 girls=72:40
etc.
Step-by-step explanation:
think of it as fractions
1/4
1/2 × 2/3
= 1×3 = 1
2×2 = 4
Therefore,
1/2 × 2/3 = 1/4//
, 3, 5 are the prime factors of 60.
2=log(3x+4)
y = loga b a^y = b
since this is base 10
10^2 =3x+4
100 = 3x+4
subtract 4 from each side
96 =3x
divide by 3
32=x
