Step-by-step explanation:
cross multiply
4(12) = 5f
48 = 5f
48/5 = f
9 3/5
a) <u>n² + 6 </u>
~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.
- If n = 1, first term = 1² + 6 = 7
- n = 2, second term = 10
- n = 3, third temm = 15
- n = 4, fourth term = 22
- n = 10, tenth term = 106
b) <u>3n²</u>
- If n = 1, first term = 3
- n = 2, second term = 12
- n = 3, third term = 27
- n = 4, fourth term = 48
- n = 10, tenth term = 300
Answer:
Step-by-step explanation:
The cost of 3 tickets is 6 dollars. divide 6 by 3 to get the cost of one ticket, which would be two dollars a ticket. with this in mind we'll complete the table
6 12 14 18 20
3 6 7 9 10
6 pounds.
First, find the amount she spent. 70 - 18.88 = 51.12
Now, just divide 51.12 by the cost per pound. 51.12 / 8.52 = 6
So, Karen purchased 6 pounds of coffee.
