Answer:
0.3x= 0.01x+2.9 -->
--> -0.01x -0.01x -->
--> 0.29x= 2.9 -->
--> /0.29 /0.29 -->
--> x=10
Step-by-step explanation:
1: subtract 0.01x from both sides
2: divide your answer (0.29) on both sides
3. you answer is now whatever x is (10)

|x-323|<50: answer
Step-by-step explanation :
For water to be a liquid, the temperature must be within 50 Kelvin of 323 K.
So, the range of the temperature of water will lie between 50 kelvin more than 323 kelvin and 50 kelvin less than 323.
The equation that can be used to determine the maximum temperature at which water is a liquid can be given by : x < 323 + 50
The equation that can be used to determine the minimum temperature at which water is a liquid can be given by : x > 323 - 50
So the resultant equation can be written as :
|x-323|<50
Answer:
Converting the equation 
into completing the square method we get: 
Step-by-step explanation:
we are given quadratic equation:
And we need to convert it into completing the square method.
Completing the square method is of form: 
Looking at the given equation
We have a = x
then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20
So, 20x in form of 2ab can be written as: 2(x)(10)
So, we need to add and subtract (10)^2 on both sides
So, converting the equation into completing the square method we get:
Answer:
-2
Step-by-step explanation:
-7 + 5 = -2
If you have negatives and then add, the negative number will decrease.
if the question was -7 - 5, the answer would be -12. This is because when you subtract a number from a negative, the negative number becomes bigger.
