Answer given below
Step-by-step explanation:
D = - 6 x 5 = - 30
okay so you did 1-5
Ima do 6-10
(if you didn’t do 1-5) just comment
6)
1/12+1/x=1/6
Multiply all terms by x
you’d get
1x/12+1=1x/6
Now solve that
You’d get 12
7)
1/12+1/x=2
Multipyl each term by x
1x/12+1 = 1x/2
Solve
you’d get
x=2.4
8)
1/8+1/x=1/4
Multiply x
1x/8+1=1x/4
Now solve
x=8
9)
1/10+1/11=1/x
Add 1/10+1/11 and get 21/110=1/x
Solve in proportion
get 5.24
10)
1/6+1/x=1/5
Multiply each by x
1x/6+1=1x/5
Solve
get 30
You’d get 110.21

Answer:
Step-by-step explanation:
Fixed monthly fee = $20
Amount charged per minute for long distance calls = $0.20
denotes total cost such that 
minutes are used for long distance calls.
Amount charged for minutes for long distance calls 
Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is
Answer:
-14
Step-by-step explanation:
Since x is negative, the median of the set is 14. Therefore, the mean of the set is 14 + 5 = 19, and its sum is 19 · 5 = 95. Since 12, 38, 45, and 14 sum to 109, the remaining integer x must be 95 − 109 = −14 .
