For this case, the first thing we must do is define variables.
We have then:
x: number of trips.
y: amount of money remaining.
We now write the equation for each person.
For Kaisorn we have:
Pata Thom we have:
Answer:
The system of equations that represents this situation is given by:
Step-by-step explanation:
I know that 44÷4=11. So that means P must be 11. But since it's subtracted by 7 we must solve 11+7. Which is 18. So P=18.
Answer:
10 people. The most obvious question of the century.
Step-by-step explanation:
Given that a tree of height
meters has
approximately
branches, where
. Each branch has
approximately
leaves where
.
(b) Consider a tree of height meters. Use the model
above to find an expression for the approximate number of leaves on
the tree. Give your answer in terms of y.
The approximate number of branches on the tree of height
is given by
The approximate number of leaves on each branch is
,
Given that there are
branches on the three.
Therefore, the approximate number of leaves on the tree is given by
