Answer:
Step-by-step explanation:
Given
Let
f = Father's age
s = Son's age
We'll solve this question, while reading through the instructions
From the first statement;
f is 2 less than 7 times s.
This means
In two years time, the father will be f +2 and the son will be s + 2
So, their sum is:
Collect like terns
So, the equations are:
Answer: The number of pounds each camel have to carry=44 pounds
The pounds of goods left=3 pounds
Step-by-step explanation:
The total pounds of goods the merchant have=
=487 pounds
The total number of camels the merchant have = 11
If each camel carry same weight of goods, then we divide total weight by 11, we get
487÷11=44.27
The number of pounds each camel have to carry=44 pounds
The pounds of goods left=487-44×11=487-484=3 pounds
The first three can be selected in 9c3 ways which equals 84.
The second three can be selected in 6c3 ways which equals 20.
Then the third set of three can be selected in 3c3 which equals 1 way.
Now we want three things to happen, so multiply 84 and 20 and you get 1680.
The order of this does not matter so divide 1680 by 3 and you have 280!!
