Answer:
It is 5:15
Step-by-step explanation:
Answer:
you are already in the hundredths
Step-by-step explanation:
5.48
5= the ones place
4= the tenths place
8= the hundredths
Adding 4 tens and 6 tens is the same as 40 + 60. 40 + 60 = 1,000
Answer: ![4x^{2} +9xy+6y^{2}](https://tex.z-dn.net/?f=4x%5E%7B2%7D%20%2B9xy%2B6y%5E%7B2%7D)
Step-by-step explanation:
First equation
![2 x^{2} +3xy-5y^{2}](https://tex.z-dn.net/?f=2%20x%5E%7B2%7D%20%2B3xy-5y%5E%7B2%7D)
Second equation
![x^{2} -7xy-4y^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-7xy-4y%5E%7B2%7D)
Third equation
![7x^{2} +5xy-3y^{2}](https://tex.z-dn.net/?f=7x%5E%7B2%7D%20%2B5xy-3y%5E%7B2%7D)
![3x^{2} -4xy-9y^{2}](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20-4xy-9y%5E%7B2%7D)
Sum of the following of two valuable equation first and second
![(2x^{2} +3xy-5y^{2} ) + (x^{2} -7xy-4y^{2} )](https://tex.z-dn.net/?f=%282x%5E%7B2%7D%20%2B3xy-5y%5E%7B2%7D%20%29%20%2B%20%28x%5E%7B2%7D%20-7xy-4y%5E%7B2%7D%20%29)
![(2+1) x^{2} +(3-7)xy+(-5-4)y^{2}](https://tex.z-dn.net/?f=%282%2B1%29%20x%5E%7B2%7D%20%2B%283-7%29xy%2B%28-5-4%29y%5E%7B2%7D)
![3x^{2} -4xy-9y^{2}](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20-4xy-9y%5E%7B2%7D)
Subtract third equation from the sum of two valuable expression
![(7x^{2} +5xy-3y^{2} ) - (3x^{2} -4xy-9y^{2} )](https://tex.z-dn.net/?f=%287x%5E%7B2%7D%20%2B5xy-3y%5E%7B2%7D%20%29%20-%20%283x%5E%7B2%7D%20-4xy-9y%5E%7B2%7D%20%29)
