30 × 5 = 150
150 - 110 = 40
40 ÷ 2 = 20
So 20 kids brought their own lunch
Hope this helped. Have a great day!
3√24= 3√2^2*6 = 3*2√6 = 6√6
2√384= 2√8^2*6 = 2*8√6 = 16√6
√96= √4^2*6 = 4√6
6√6 -16√6- 4√6 = -14√6
Final answer: -14√6
Well, her initial investment happened at day 0, namely x = 0, let's check,
Each grandchild receives x.
Each child receives 2 times as much as a grandchild, so each child receives 2x.
The wife receives 5 times as much as a child, so the wife receives 5 * 2x = 10x.
There is 1 wife: 10x
There are 2 children: 2 * 2x = 4x
There are 3 grandchildren: 3x
Total: 10x + 4x + 3x = 17x
17x = 510,000
x = 30,000
Answer:
Each grandchild gets $30,000.
Each child gets 2 * $30,000 = $60,000.
The wife gets 10 * $30,000 = $300,000.
