If one number is ten times the other one, then the big wide open space
between them with the wind blowing through it is the other nine times it.
The 27 years is 9 times Mel's age.
Mel is 27/9 =<em> 3 years old</em>.
Lane is (3 + 27) = 30 years old.
Lane is (30/3) = 10 times Mel's age.
The difference is (30 - 3) = 27 years.

"Stan and Hilda can mow the lawn in 35 min"
35 = 1/(S + H)
"Hilda works twice as fast as Stan"
H = 2S
"how long would it take Stan to mow the lawn alone?"
T = 1/S
First, let's determine what S is, so
35 = 1/(S + H)
Substitute 2S for H
35 = 1/(S + 2S)
Solve for S
35 = 1/(3S)
35(3S) = 1)
105S = 1
S = 1/105
Now solve T = 1/S with S = 1/105
T = 1/S
T = 1/(1/105)
T = 1/1 / 1/105
T = 1/1 * 105/1
T = 105
So it will take Stan 105 minutes to mow the lawn alone.</span>

Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
= 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
= 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
= 9138.44 dollars
So option "C" is the correct option in regards to the question given.
Answer:
5x-15=x+13
Step-by-step explanation:
I don't know which equation you want me to simplify, so I assume it is, 5(x – 3) = x + 13?
