Answer:

x = 5

Step-by-step explanation:

To solve this equation, we will have to solve for x.

4x = 38 - 2(x + 4)

Distribute the 2 on the right side of the equation.

4x = 30 - 2x - 8

Combine like terms.

4x = 30 - 2x

Add 2x to both sides of the equation.

6x = 30

Divide both sides by 6.

x = 5

So the solution to the equation would be x = 5.

I hope you find my answer and explanation helpful. Happy studying. :)

30 girls , 12 were selected

40 boys, 16 were selected

We can simplify these down by finding the Greatest Common Factor in both girls and boys:

30:12 .... 15:6 .... 1 : 2.5 30/12 .... 15/6 .... 2.5

40:16 .... 20:8 .... 1 : 2.5 OR 40/16 .... 20/8 .... 2.5

They are equal ratios because their most simplified ratios/fractions are equivalent

You roll a number cube. Find the probability and write your answer in the simplest form. P(4)= ---------------------------------

alina1380 [7]

Answer:

$P(4) = \frac{1}{6}$

$P(\text{not a 2}) = \frac{5}{6}$

$P(\text{3 or 5}) = \frac{1}{3}$

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Number cube:

A number cube is a dice, which has six sides, numbered 1 to 6.

P(4)

One the sides is a 4, thus:

$P(4) = \frac{1}{6}$

P(not a 2)

Of the 6 sides, one is a 2, and the other 5 are not 2. So

$P(\text{not a 2}) = \frac{5}{6}$

P(3 or 5)

One sides is 3, other is 5, 1 + 1 = 2. So

$P(\text{3 or 5}) = \frac{2}{6} = \frac{1}{3}$
