Because you divide by 109
Let X represent Karma's fathers age and Y represent Karma's age. The first term can be found using this formula:
Y = 1/3X → 5 Years ago
Y = 1/2X → 5 Years from now
From mental math, I can concur she's 15 and her father is 35. Then we plug in to check.
1/3(30) = 10 √ (Five years ago).
1/2(40) = 20 √ (Five years from current).
Their current ages are 15 and 35.
Answer:
Step-by-step explanation:
-12 = 12 ....this is incorrect...meaning no solutions
**
if it ended in :
x = a number, or y = a number...means there is 1 solution
if it ended in :
-12 = 12....incorrect answer, means there is no solutions
if it ended in :
2 = 2 or -4 = -4....correct answer, but not variable...means infinite solutions
You must convert the percentage to decimal notation and then multiply it by 72.

So the 310% of 72 is:
