Answer:
53
Step-by-step explanation:
Given: The sum of two digit number is 8
Reversing the digit will get us number 18 less than the original.
Lets take x as tenth digit of our number and y as unit digit of our number.
As given sum of digit is 8
∴ 
∴ 
- equation 1
We also know that reversing the digit will get us number 18 less than the original.
∴ 
Now, lets put the value of y from equation 1
⇒ 
⇒ 
⇒ 
∴ 
Next, substituting the value of x in equation 1
⇒ 
∴ 
∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.

Answer:he would require 8.33 gallons of gas
Step-by-step explanation:
Mr Dow lives 16 miles from his workplace he drives to and from work five days a week. It means that the distance that he drives everyday to and from work would be
16 × 2 = 32 miles.
Then, the total distance that he drives in a week to and from work would be
32 × 5 = 160 miles
if his car gets 19.2 miles per gallon, it means that the amount of gas that he would use in one week, commuting to and from work would be
160/19.2 = 8.33 gallons
