Answer:
Step-by-step explanation:
1) if according to the condition a₁=3 and r=2/3, then a₁₀ can be calculated as:
a₁₀=a₁*r⁹;
2) according to the rule above:
a₁₀=3*(2/3)⁹=512*3/(6561*3)=512/6561.
kids at zoo, k = 325
percentage boys, b = 64%
percentage girls, g = 100 - b = 36%
number of girls = 325 × 36% = 117
X=2
because if you subtract 3x on both sides you end up with x=2 <span />
