The picture isn't loading so i'll answer based on what is shown.
If x-4=-2, then x is 2.
Answer:
1 pm = 56 7pm = 46 not fully sure
Step-by-step explanation:
Answer with Step-by-step explanation:
Since 1 mole of sand will contain Avagadro's Number of sand particles (by definition of 1 mole)
Thus we have
1 mole of sand = sand particles
Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is
Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of trillion sand particles is
Part 2)
Since it is given that volume of 1 sand particle is thus the volume of 1 mole of sand is volume of sand particles
Thus volume of 1 mole is
Now since the Area of united states is
Thus the depth of the sand pile is
Answer:
(x - 3)(x - 1)
Step-by-step explanation:
Consider the factors of the constant term (+ 3) which sum to give the coefficient of the x- term.
The factors are - 3 and - 1, since
- 3 × - 1 = + 3 and - 3 - 1 = - 4, hence
x² - 4x + 3 = (x - 3)(x - 1) ← in factored form
Given:
The given system of equations is
To find:
The solution of the given system of equations.
Solution:
We have,
...(i)
...(ii)
Left hand sides of both equations are equal. So, after equalization of (i) and (ii), we get
This statement is false for any value of x and y. It means the given system of equation has no solution.
Therefore, the correct option is C.
