Answer: So, the required inequality that can be used to represent this situation is 2x+3\leq 31

Step-by-step explanation:

Let the age of Catie's brother be 'x'.

Let the age of Catie be 'x+3'.

According to question, the sum of their ages is no more than 31.

So, it becomes,

x+x+3\leq 31\\\\2x+3\leq 31

So, the required inequality that can be used to represent this situation is

2x+3\leq 31

If the cube above has a surface area of 54cm^3, what is the volume of the cube?
Colt1911 [192]

9514 1404 393

Answer:

  27 cm³

Step-by-step explanation:

The surface area of a cube is ...

  SA = 6s²

Then the edge length is ...

  54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area

  9 cm² = s² . . . . . .divide by 6

  3 cm = s . . . . . . . take the square root

The volume of a cube is ...

  V = s³

  V = (3 cm)³ = 27 cm³

The volume of the cube is 27 cm³.

Solve the equation 2(x-4)=-22
Tcecarenko [31]

Hello Lexi!

<u><em>Answer:  ⇒⇒⇒⇒⇒⇒ x=-7</em></u>

__________________________________________________________

Step-by-step explanation:

First you had to divide by 2 from both sides of equation.

\frac{2(x-4)}{2}=\frac{-22}{2}

Simplify.

\frac{2(x-4)}{2}=x-4

\frac{2(x-4)}{2}

Divide by the numbers.

\frac{2}{2}=1

=x-4

\frac{-22}{2}=-11

Apply the fraction rule.

\frac{-22}{2}

=-\frac{22}{2}

Then you divide by the number.

\frac{22}{2}=11

=-11

x-4=-11

Add by 4 from both sides of equation.

x-4+4=-11+4

Simplify it should be the correct answer.

x=-7
