Answer: 7
Step-by-step explanation: 3/7 is 0.4 so 7.4 rounded to the nearest whole is 7
Two consecutive odd number have the form: 2n+1; 2n+3.
We have:
(2n+1)(2n+3)=399
=> 4x^2+8x+3=399
=> 4x^2+8x-396=0
=> 4(x+11)(x-9)=0
=> x=-11; x=9
47 - 5*3 - 2*1 = 30. 30/3 = 3, so add three plus five plus two = 10 kids
