Answer:
the common difference of the sequence is
Step-by-step explanation:
A sequence of numbers is said to be in arithmetic progression of each term of the sequence has same common difference.
Now, here first term a1 = 1/4
Second term a2 = 5/16
Third term a3 = 3/8
Now, Common difference (d) = a2 - a1 = a3 - a2
Now, a2 - a1 =
Now, a3 - a2 =
Hence, the common difference of the sequence is
Answer:
Step-by-step explanation:
Let x represent number of small candles and y represent number of large candles.
We have been given that Jonah needs to buy at least 20 candles. This means number of small and large candles should be greater than or equal to 20. We can represent this information in an inequality as:
We are also told that small candles cost $3.50, so cost of x small candles would be .
Since large candles cost $5.00, so cost of y large candles would be .
We are told that Jonah cannot spend more than $80, this means cost of x small candles and y large candles should be less than or equal to $80. We can represent this information in an inequality as:
Therefore, our required system of inequalities would be:
