54 divided by _____ = -27
Nikitich [7]

54/-2 = -27

First, let's rewrite:

Let x represent the unknown number:

\frac{54}{x}=\text{ -27}

\begin{gathered} \frac{54}{x}\text{ = -27} \\ 54\text{ = -27x} \\ \text{Divide both sides by -27} \\ \frac{54}{-27}=\text{ }\frac{-27x}{-27} \end{gathered}\begin{gathered} 27\times2\text{ = 54} \\ x\text{ = -2  (because we are dividing positive number by a negative number)} \\ So\text{ our answer will be negative} \end{gathered}

Hence, 54/-2 = -27

The volume of a cube related to the area of a face by the formula V =A^3/2. What is the volume of a cube whose face has an area
11111nata11111 [884]

Answer:

Volume = 125 mm^3

Step-by-step explanation:

Here, we want to get the volume of the cube

What we have to do here is to substitute the value of the area

We have this as

:

V = 25^(3/2)

V = (√25)^3

V = 5 * 5 * 5 = 125 mm^3

Given the equation −4Square root of x minus 3 = 12, solve for x and identify if it is an extraneous solution.
Darina [25.2K]

Answer:

There is no solution for the given radical equation.

x = 225/16 is an extraneous solution.

Step-by-step explanation:

The given equation is  

Add 3 to both sides of the equation

Squaring both sides

Divide both sides by 16

Substituting back the value of x in original equation to check the extraneous solution.

 

Since -18≠ 12. Hence, the value of x does not satisfy the equation.

Therefore, x = 225/16 is an extraneous solution.
