Answer:
i) 4x
ii) Father's age = 3(x + 10)
Son's age = x + 10
iii) 4x + 10 = 3(x + 10)
iv) Present age of the son = x = 20
Present age of the father = 4x = 4(20)
= 80
Step-by-step explanation:
Present age of the son = x
Present age of the father = 4x
Age of the son in 10 years = x + 10
Age of the father in 10 years = 3(x + 10)
4x + 10 = 3(x + 10)
4x + 10 = 3x + 30
4x - 3x = 30 - 10
x = 20
Answer:
280
Step-by-step explanation:
30/100 = 84/x
84 x 100 = 8400
8400/30 = 280

15 + 2(2 * 4) - 4^2
= 15 + 2(8) - 4^2
= 15 + 16 - 4^2
= 31 - 4^2
= 31 - 4 * 4
= 31 - 16
= 15
Therefore, your answer is: 15

Answer: The answer is 12 ways.
Step-by-step explanation: Given that For members of Abe's family are travelling to Canada for vacations. They have four seats in the centre section of the plane. Also, Abe wants to sit next to his brother Ben. We need to find the number of ways in which they can sit.
Since Abe will sit next to his brother Ben, so we can count both of them as one. Hence, taking them as one member, three members can sit in 3! ways.
Also, Abe and Ben among themselves can sit in 2! ways.
Therefore, the total number of ways in which they can sit
= 3! × 2!
=3 × 2 × 1 × 2 × 1
=12.
Thus, the number of ways is 12.
First, you add -3 to itself 7 times.
Then, add the distance he went to the distance he's already went.
Do -96--36 to find how far he is from the ocean floor.
So, he is 60m from the ocean floor
