x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7
One is colder than the other.
Hope this helps :)
You stop at 2 decimal points. If the 3rd decimal is bigger than 5, add 1 to the 2nd and if it's less than 5, keep it as it is.
For example:
2.663 --> 2.66
6.788 --> 6.79
Answer:
3)5x-4y=-3
6x+4y=14
Step-by-step explanation:
The system of equations is given
5x-4y=-3
3x+2y=7
Multiplying both sides of the lower equation by 2, we get
6x + 4y = 14
That means your answer 3)
