Answer:
The distance between airport and Ann's home is 21 miles
Step-by-step explanation:
Given Ann took a taxi home from the airport. The taxi fare was $2.10 per mile, and she gave the driver a tip of $5. Ann paid a total of $49.10. we have to find the equation to determine the distance in miles between the airport and Ann's home.
Let the distance between airport and Ann's home be x miles.
Given, Total fare = $2.10/mile
Tip given = $5
Total money given=$49.10
∴ Equation can be written as
(Taxi fare per mile)(distance)+tip = total money given
⇒
⇒ ⇒ x=21
Hence, the distance between airport and Ann's home is 21 miles
Answer:
35.6%
Step-by-step explanation:
31/87(100)
3100/87
35.6%
We'll call this number
We have
⇒
Since
is divisible by 5, it is either 0 or 5
But it can't be 0, because then
would be 0
So
and
Now I'm assuming that the second and third digits are
adding to three times the last digit.
So
⇒
We have a number of options:
So the possibilities are:
1695
1785
1875
1965
(If there were another detail we could narrow down the choices further, but otherwise we have all these options.)
