Answer:
= 4
Step-by-step explanation:
There is a common ratio r between consecutive terms , that is
r = - 20 ÷ 4 = 100 ÷ - 20 = - 5
This indicates the sequence is geometric with nth term ( explicit formula )
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 4 and r = - 5 , then
= 4
Answer:
Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.
Step-by-step explanation:
Given that
1 pound of ground beef sells for $4.
To find the cost per pound:
We need to divide the cost with the number of pounds.
i.e.
If 'Number of pounds' = 1, then cost per pound = Total Cost
Therefore, the above division expression can be used to find the Cost pound.
Putting the values given to find the 'Cost per pound':
Therefore, Rosa's belief is correct that, a division expression can be used.
The correct answer is:
Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.
