Step-by-step explanation:
An Arithmetic sequence is defined as a set of numbers with a common difference. In answer choice B, it is seen that the difference between each number is seven.
A is incorrect as one to eight has a difference of seven, while the other numbers have a difference of eight.
C is incorrect as it skips the number 12 between 9 and 15, thus breaking the sequence.
D is incorrect as the numbers jump from positive to negative, thus not having a common difference.
Hope this helps!
Answer:
20t
Step-by-step explanation:
Carly buys t play tickets at $14.50 per ticket and t choir concert tickets at $5.50 per ticket. What is the cost for play tickets and choir concert tickets.
The cost of the play tickets is the number of play tickets multiplied by the cost of each ticket.
Play tickets: number of tickets: t; cost of each ticket: $14.50
Cost of play tickets: 14.50t
The cost of the choir tickets is the number of choir tickets multiplied by the cost of each ticket.
Choir tickets: number of tickets: t; cost of each ticket: $5.50
Cost of choir tickets: 5.50t
Total cost of play tickets and choir tickets:
14.50t + 5.50t = 20t
No.Because 14/2=7 and 7*3=21 so $21 is the answer.
The answer is C. I solved for the first variable in one of the equations then substitute the result into the other equation.
Opposite
additive inverse
