Using Pythagoras theorem,
<em>In right triangle, squares of the hypotenuse is equal to the sum of the squares of the other two sides.</em>
Let x be the hypotenuse.
Taking square root on both sides, we get
x = 54.67
x = 54.7
The shortest distance Mark can cover to reach home early is 54.7 miles.

If you divide 189 by 8 you would get 23.625 but first you have to subtract 13 from 189 (176) then divide it (22) the answer is 22 dollars
Let number of answers correctly given by Tom = x
Number of Incorrect answers = 10
Marks given to Tim for every correct answer = 4 Marks
Marks for incorrect answer= 0
Total Score = 76
The equation , when all the above statement are combined together
→4 x + 10 × 0 = 76
→ 4 x = 76
x = 19
Number of Right Answers = 19
Number of Wrong Answer= 10
Total Question = 19 + 10= 29
