First, let's identify some variables:
d = dress price
s = shirt price
d = 3s
12s + d = 450
Because d = 3s, we can substitute the variable:
12s + 3s = 450
15s = 450
s = 30
The shirt costs $30, and the dress $10
The 8th term of the geometric sequence is 13122x^22
<h3>Explicit form of a geometric sequence</h3>
The explicit form of a geometric sequence is expressed according to the equation;
Tn = ar^n-1
where
r is the common ratio
a is the first term
n is the number of terms
Given the sequence below;
6x,18x^4,54x^7
r = 18x^4/6x
r = 3x^3
a = 6x
n = 8
Substitute to have:
T8 = 6x(3x^3)^8-1
T8 = 6x (3x^3)^7
T8 = 13122x^22
Hence the 8th term of the geometric sequence is 13122x^22

The first one and the third one are correct
Answer:
28.00
Step-by-step explanation:
You can also calculate how much you save by simply moving the period in 30.00 percent two spaces to the left, and then multiply the result by $40 as follows: $40 x . 30 = $12.00 savings.
