Answer:
<h3>The 7th term is
1458</h3>
Step-by-step explanation:
For a geometric sequence
U(n) = ar^n - 1
Where
n is the number of terms
r is the common ratio
a is the first term
From the sequence
a = 2
r = - 6 /2 = -3
U(n) = 2(-3) ^ n - 1
For the 7th term
U(7) = 2(-3) ^ 7 - 1
= 2(-3)^6
The final answer is
= 1458

Answer:
The equation is x= (7.74 /9) 6
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil.
Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.
Mathematically speaking:
x= (7.74 /9) 6
Where:
x = Cost of 6 pencils in $
Solving:
x = 0.86 x 6 = $5.16
Answer:
B
Step-by-step explanation:
Let the nickels = x
Let the dimes = y
You don't know the total value of either. Nor do you know the total number of either.
You only know the total value of both together.
7.80 added to anything makes it bigger than 7.80 A is wrong.
y cannot be alone it should be multiplied by 0.5 C is wrong
D is wrong for the same reason A is
B is the correct answer. That is the way you write the problem
Number of Coins and value on one side. Total on the other.
