27x + 9
------------
3
Break down the fraction. 3 is the common denominator, so it is the denominator of both numerators.
27x/3 + 9/3 = 0
9x + 3 = 0
9x = -3
x = -3/9 simplified to x = -1/3
Or simply multiply the fraction with 3/1 to remove the denominator, which is 3.
27x + 9 3 27x + 9
----------- x ------- = ----------------- or 27x + 9 = 0 ; look for x.
3 1 1
To check: Substitute x by its value:
(27x + 9) / 3 = 0 ⇒ ((27 * -1/3) + 9) / 3 = 0
⇒ (-9 + 9)/3 = 0 ⇒ 0/3 = 0 ⇒ 0 = 0
1. First you need to understand that 36 seconds is 1/100 of a mile.
2. An elephant can run 0.25 miles (1/4 of a mile) in 1/100 of a hour.
3. To even this out, multiply 0.25 by 100 to find how many miles per hour an elephant can run (25 miles per hour!)
Answer:
Ratio of cost of a pen to cost of a ball pen is 15:7
Step-by-step explanation:

Cost of dozen pens = ₹180
Unit rate = 
Unit rate = ₹ 15 per pen
Cost of 8 ball pens = ₹ 56
Unit rate = 
Unit rate = ₹7 per ball pen
Ratio of cost of a pen to cost of a ball pen,
15 : 7
Hence,
Ratio of cost of a pen to cost of a ball pen is 15:7
