Nicole finished her math assignment in 1/4 hours. Then she completed her chemistry assignment in 1/3 hours. How much more time d
2 answers:
1/3 of an hour (60 minutes) is 20.
1/4 of an hour is 15.
Subtract and receive 5.
So Nicole spent 5 more minutes on her chemistry assignment.
Another way to tackle this problem is to subtract the fractions after finding their common denominator (12)
4/12-3/12=1/12
1/12 of an hour is 5.
I used 2 different methods and I had the exact same answer. Hope it's helpful!

<h2><u>Solution (1)</u> :</h2>
Given, to find A we have to :
- square m
- Add y to m²
- Subtract 7 from m² + y
From the question, the following equation can be formed :
Therefore, the formula for finding A = m² + y - 7
<h2><u>Solution (2)</u> :</h2>The value of A we can derive from the formula is :
Value of m = 3 (given)
Which means :
Thus, the value of A = 2+y
Therefore, the value of A = <u>2+y</u>
