Answer:
Step-by-step explanation:
Given expression
To solve for 
for the given expression.
Solution:
We multiply each term with the least common multiple of the denominators of the fraction in order to remove fractions.
The multiples of the denominators are:
3 = 3,6,9,<u>12</u>,15
6 = 6,<u>12</u>
4 = 4,8,<u>12</u>
The least common multiple = 12.
Multiplying each term with 12.
Using distribution.
Simplifying.
Adding 
both sides.
Adding 51 both sides.
Dividing both sides by 15.
Simplifying fractions.
∴ (Answer)
Answer:
5 miles
Step-by-step explanation:
This is because if you draw a line going west and label it as 4 miles, then draw another line going south and label it 3 miles, you form a right angle, right? So, the fastest way to go back would be taking a diagonal-like route back to the beginning. Does this shape look familiar to you? Right! It's a right triangle. And do the numbers 3, 4, and 5 sound familiar to you? Yup, it's a Pythagorean triplet. If the legs of a right triangle are 3 and 4, the hypotenuse is 5. Why am I saying this? Because, in the drawing you just did, the 4 miles west and 3 miles south were the legs, and the diagonal path back to the beginning is the hypotenuse. Get it now?
