Answer:
x = 49.84
Step-by-step explanation:
We are given an equation of unknown x and we have to solve the equation for x.

⇒ 
⇒
{Since we know that ln AB =ln A + ln B}
⇒ 
⇒
{Since we know that ln A/B = ln A - ln B}
⇒ 
⇒

{Converting logarithm to exponent form}
⇒ x = 49.84 (Approximate) (Answer)
Answer: C
Step-by-step explanation: First, you have to make this word problem into a equation into standard form so 20 is our (y) because that is the additional charge, but our slope is 3, that is what they charge per hour.
Answer:
x = 12
Step-by-step explanation:
This equation is very easy to solve.
3x - 13 = 23 Add 13 to both sides of the equation.
3x = 36 Divide by 3 on both sides of the equation.
x = 12
Then, check your answer by substituting the solved value.
3(12) - 13 = 23
36 - 13 = 23
23 = 23
Therefore, x = 12 is the solution to the equation.
