Answer:

<h2>x = 28</h2>

Step-by-step explanation:

\frac{3}{4}( x - 12) = 12

Multiply through by 4 to eliminate the fraction

That's

4 \times  \frac{3}{4} (x - 12) = 12 \times 4 \\ 3(x - 12) = 48

<u>Expand the terms in the bracket</u>

3x - 36 = 48

<u>Add 36 to both sides of the equation</u>

That's

3x + 36 - 36 = 48 + 36 \\ 3x = 84

<u>Divide both sides by 3</u>

\frac{3x}{3}  =  \frac{84}{ 3}  \\

We have the final answer as

<h3>x = 28</h3>

Hope this helps you

Consider the function represented by the equation y minus 6 x minus 9 = 0. Which answer shows the equation written in function n
Nataly [62]

Answer: First option.

Step-by-step explanation:

You know that the function represented by the equation is the following:

y-6x-9=0

Then, you can follow these steps in order write the equation in function notation with "x" as the independent variable:

1. Solve for "y":

Add 6x to both sides:

y-6x-9+6x=0+6x\\\\y-9=6x

Add 9 to both sides:

y-9+9=6x+9\\\\y=6x+9

2. Since f(x) is a common way of representing "y", you get:

f(x)=6x+9

At a picnic there were 3 times as many adults as children and twice as many women as men. If there was a total of x men, women,
Dennis_Churaev [7]

Answer:

\dfrac{x}{4}

C is correct.

Step-by-step explanation:

At a picnic,

Number of adults is 3 times as number of children.

Number of women is twice as number of men.

Total number of men, women and children at the picnic be x

Let number of children be c

Let number of men be m

Let number of women be w

# Number of women is twice as number of men, w = 2m

# Number of adults is 3 times as number of children, w + m = 3c

      2m + m = 3c     (∴  w=2m )

                c = m

Total number of men, women and children at the picnic be x

∵       c + m + w = x

     m + m + 2m = x

                    4m = x

Number of men, m=\dfrac{x}{4}

Hence, The total number of men will be  \dfrac{x}{4}
