Half is a third of it.what is it?
Sati [7]
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

Answer:

x=10

y=-2

(10,-2)

Step-by-step explanation:

If X=10, we can put 10 in for x in the equation.

30 + 5y = 20

Next, we need to solve to find y.

We will get y on its own so we subtract 30 from 20 to get

5y=-10

We then know that 5 goes into -10 -2 times.

y=-2

What is the sum of the probabilities of the favorable outcomes and the unfavorable outcomes, p(x=1)+p(x≠1)p(x=1)+p(x≠1)?
Drupady [299]

What's the sample space? Are we talking about rolling a die or what?


Anyway, if we call the probability p(x=1) = x, then p(x\neq 1) = 1-x


So, the expression becomes


x + (1-x)x + (1-x) = x + x - x^2 + 1 - x = -x^2+x+1
