Just substitute their values into the expression:
= -8 + 9 + 5z + 7x
= -8 + 9 + 5(3) + 7(5)
= 1 + 15 + 35
= 51
In short, Your Answer would be 51
Hope this helps!
I'm assuming that is f(x) = (x-1)/x
In that case, the answer would be just x = 1.
However, if the original is f(x) = x - (1/x) the answer would be x = 1 and x = -1.
It's really just a formatting thing—if the given equation is indeed f(x) = (x-1)/x then x = 1 is the answer.

B)OPTION B only 1 is your answer.
Answer: 11am
Step-by-step explanation:
To solve this, we have to calculate the lowest common multiple of 20 and 30. This will be:
20 = 20, 40, 60, 80, 100
30 = 30, 60, 90, 120, 150.
Here, the lowest common multiple is 60.
Therefore, we add 60 minutes to 10am. This will be:
= 10am + 1 hour
= 11 am
The next time that both buses leave at the same time would be 11am
For On call = 10/3.5 = $2.85 for per hour
For talk time 1.25/1/2= $2.5 for per hour
