Answer:
y = -2x - 12
Step-by-step explanation:
For this case we must simplify the following expression:
![\frac {2} {5} - (- \frac {3} {4})](https://tex.z-dn.net/?f=%5Cfrac%20%7B2%7D%20%7B5%7D%20-%20%28-%20%5Cfrac%20%7B3%7D%20%7B4%7D%29)
By definition of the law of multiplication signs we have to:
![- * - = +](https://tex.z-dn.net/?f=-%20%2A%20-%20%3D%20%2B)
So, rewriting the expression we have:
![\frac {2} {5} + \frac {3} {4} =\\\frac {4 * 2 + 5 * 3} {5 * 4} =\\\frac {8 + 15} {20} =\\\frac {23} {20} = 1.15](https://tex.z-dn.net/?f=%5Cfrac%20%7B2%7D%20%7B5%7D%20%2B%20%5Cfrac%20%7B3%7D%20%7B4%7D%20%3D%5C%5C%5Cfrac%20%7B4%20%2A%202%20%2B%205%20%2A%203%7D%20%7B5%20%2A%204%7D%20%3D%5C%5C%5Cfrac%20%7B8%20%2B%2015%7D%20%7B20%7D%20%3D%5C%5C%5Cfrac%20%7B23%7D%20%7B20%7D%20%3D%201.15)
Thus, the answer in decimal form is 1.15.
Answer:
![\frac {23} {20} = 1.15](https://tex.z-dn.net/?f=%5Cfrac%20%7B23%7D%20%7B20%7D%20%3D%201.15)
For every hour. It will leak a half of cup (1/2). If 30 mins= 1/4 of a cup. Times it but two. 60 or 1 hour = 2/4 or simplified 1/2
The answer is 567:
I got the answer by doing nothing then I did nothing and finally I did nothing hope you find this helpful as I just wasted your time
