Answer:
Option A, C and D are correct.
Step-by-step explanation:
Option A is correct because if we take example of 
we get:
1,2,1
1,3,3,1
1,4,6,4,1
So we can see that either we read left to right or right to left we are getting same row
Option B is not correct because When we take power zero it will occupy first row hence, 
is not given by nth row.
Option C is correct because adding adjacent terms on a will give us the term directly below look at the example in option A.
Option D is correct because nth row will give coefficients in the expansion of (x + y) n-1 since, zero will occupy first row hence, nth row will be n-1.
The correct answer is 10/7 or 1 3/7. Hope this helps.
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>
