Answer:

Step-by-step explanation

So you need the fraction to equal 2.4 and you don't know the numerator. 5 times 2.4 equals 12 so the numerator has to equal 12 so the answer is c

Answer:

x = 4

Step-by-step explanation:

Undo what is done to the variable, in reverse order. The variable is multiplied by 3/5 and 0.5 is subtracted from the result.

To undo those operations, first you undo the subtraction by adding 0.5 to both sides of the equation. This gives you ...

3x/5 = 2.4

To undo the multiplication by 3/5, you can multiply by the inverse of that value, 5/3. Multiplying both sides of the equation by 5/3 gives ...

x = (5/3)(2.4) = 12/3

x = 4

Answer:

C) 14

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 6 to both sides:

3x - 6 (+6) = 36 (+6)

3x = 36 + 6

3x = 42

Next, divide 3 from both sides:

(3x)/3 = (42)/3

x = 42/3

x = 14

c) 14 is your answer.

Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous

Dmitriy789 [7]

Answer:

Solution: $x=-\frac{1}{5}$ , $x=0$

Step-by-step explanation:

Given:

The rational equation to solve is given as:

$\frac{x}{6}=\frac{x^2}{x-1}$

Doing cross product, we get:

$x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}$

Now, for $x=0$ , the rational equation is equal to 0. So, $x=0$ is a solution.

Also, $x=-\frac{1}{5}$ is also a solution.

So, no extraneous solution.
