Answer:


Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
so
The distance is equal to multiply the speed by the time
Let
s ----> the speed in units per second
d ---> the distance in units
t ---> is the time in seconds
BUG A
we have


The speed is equal to

substitute

If x is the point reached by A after t seconds
then
Multiply the speed by the time


BUG B
we have


The speed is equal to

substitute

If y is the point reached by B after t seconds
then
Multiply the speed by the time

----> is negative because B is moving in the negative direction
Answer:
The man has 6 GHc20.00 notes and 4 GHc10.00 left
Step-by-step explanation:
Given
Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00
Spendings = GH¢80,00
Required
Determine how many GH¢20.00 and GH¢10.00 notes left
The amount he has can be represented as:


This can be represented as:

Represent:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
So, we have:





Subtract the spendings from the total to get amount left


Collect Like Terms


Recall that, we have represented:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
<em>This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left</em>
