Answer:
Step-by-step explanation:
Use the 10th row of Pascal's Triangle to get you where you need to be. You need 10 rows because any polynomial raised to the 9th power has 10 terms. Those 10 terms are, in order:
1, 9, 36, 84, 126, 126, 84, 36, 9, 1
Setting up for the first 6 terms:
The 6th term is the last one. It goes on from there, but I stopped at the 6th term, since that is what you need.
Simplifying gives us:
and multiplying gives us:
Answer:
m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.
Step-by-step explanation:
Given,
Total cost of maths book and novel = $54
Let,
Cost of maths book = m
Cost of novel = n
According to given statement;
m+n=54 Eqn 1
the price of the math textbook, m, is $8 more than 3 times the price of the novel
m = 3n+8 Eqn 2
m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.
Step-by-step explanation:
Hi,
The ratio is 42:35
Simplest form = 6:5(divide both by 7)
Hope this helps you.
