Answer:
B
Step-by-step explanation:
Let's call 'it' x. 1/2 is equal to one third of x, so we could say that 1/3x = 1/2
Now we just have a simple equation to solve:
1/3x = 1/2
x = (1/2) / (1/3)
Dividing by a rational number (such as 1/3, which is expressed in fraction form) is the same as multiplying by its reciprocal (the reciprocal of a fraction is itself when the numerator and denominator have been swapped). Therefore
x = (1/2) / (1/3) = (1/2) * 3 = 3/2 = 1.5
To check this answer, test the statement. Half is a third of x, where x=1.5:
1.5 / 3 = 0.5 = 1/2
I guess the mean is always

Answer:
4x + 1 and 6x - 2x - 2 + 3
Step-by-step explanation:
we can expand and find 2 equations that are the same as this
one being 6x+3 -2x -2
and another being 4x + 1
hope this helps!
To simplify, you must distribute the 2 into the 5x and -4 by multiplying 2 with 5x and 2 with -4.
<span>2(5x – 4) + 3x
2 x 5x = 10x
2 x -4 = -8
You will get 10x - 8 + 3x
Now you must combine like terms or add like terms. In this case we must add 10x and 3x
10x + 3x = 13x
Finally the answer would be 13x - 8</span>
