The number would have to be <u>16</u>. 64 does not divide by 24, 28, or 36 to equal any whole number
Answer:
29
Just replace n by 8 ===> C(8) = -6+5(8-1) = - 6 + 5x7 = -6+35 = 29
Step-by-step explanation:
We have been given a sequence formula. We are asked to find the 8th term of our given sequence.
We know that an arithmetic sequence is in form A_n=a_1+(n-1)d, where,
A_n=\text{ nth term of sequence},
A_1=\text{ 1st term of sequence},
n = Number of terms in sequence,
d = Common difference.
To find the 8th term of our given sequence, we will substitute n=8 in our given formula.
c(n)=-6+5(n-1)
c(8)=-6+5(8-1)
c(8)=-6+5(7)
c(8)=-6+35
15/7 x 5 and 2/5 x 7
75/35 - 14/35 = 61/35
For a problem like this, you'll want to break it down ...
Total cost = $19.60.
Cost of beads = $12.80.
Cost of pendant = ?
We know that there are 4 necklaces. Each necklace has one pendant, so we have 5 pendants total. Therefore, your solution should look something like this ...
Total cost = Cost of beads - cost of pendant
$19.60 = 12.80 - 4x <- x is the variable representing the price for a single pendant.
6.80 = 4x <- Subtract 12.80 from both sides.
x = 1.70 <- Divide both sides by 4, and find your final answer.
x = 1.70; therfore, each pendant costs $1.70.
