Answer:
"<em>the summation from n equals one to 6 of quantity negative 7 minus 3 times n</em>"
Step-by-step explanation:
<u>General term of an arithmetic sequence:</u>

Where
is the first term
n is the number of terms
r is the common difference
The value of r can be found by subtracting two consecutive values

Then

If we want to sum the first six terms of the sequence, we must find

The correct option is
"the summation from n equals one to 6 of quantity negative 7 minus 3 times n"
Answer:
UT + CV = 4x + 33
Step-by-step explanation:
Given:
TW = 14
WU = 2x + 2
VW = 2x + 5
WC = 12
Find:
UT + CV
Computation:
UT = TW + WU
UT = 14 + 2x + 2 = 16 + 2x
CV = VW + WC
CV = 2x + 5 + 12 = 2x + 17
UT + CV
16 + 2x + 2x + 17
UT + CV = 4x + 33
First, you have to solve t(x) when x=4, because the crew is working 4 scripts. Which is t(x)=4+6
t(x)=10
Then, you plug in t(x) to c(x).
c(x)=2(10)+4
c(x)=24
