\boldsymbol{\sf{3(x-4) > 5x +2 }}

Use the distributive property to multiply 3 by x−4.

\boldsymbol{\sf{3x-12 > 5x+2 }}

Subtract 5x on both sides.

\boldsymbol{\sf{3x-12-5x > 2 } }

Combine 3x and −5x to get −2x.

\boldsymbol{\sf{-2x-12 > 2 }}

Add 12 to both sides.

\boldsymbol{\sf{-2x > 2+12 \ \longmapsto \ \ [Add \ 2 +12]}}

\boldsymbol{\sf{-2x > 14}}

Divide both sides by −2. Since −2 is < 0, the inequality direction is changed.

\boldsymbol{\sf{x < \dfrac{14}{-2} \ \ \longmapsto \ \ \ [Split]}}

\boxed{\boldsymbol{\sf{x < -7 }}}

So in the <u>inequality 3(x-4)>5x +2</u>, the value of x is -7.

Beef hope me I need you to answer the question. What is n * 54 - 688-20 =???³
blsea [12.9K]

Answer:n= 1/3d - 2/3m

Step-by-step explanation:

d=2m+3n

Step 1: Flip the equation.

2m+3n=d

Step 2: Add -2m to both sides.

2m+3n+−2m=d+−2m

3n=d−2m

Step 3: Divide both sides by 3.

3n/3 = d-2m/3

Therefore

n= 1/3d - 2/3m

Hope this helps!

Plz name brainliest if possible.

Answer:

n = d - 2m

        3*

Step-by-step explanation:

First we want to get n alone on one side, so we should subtract 2m from both side;

d = 2m + 3n

3n = d - 2m

Now to get n by itself, we need to divide by 3 from both sides;

3n = d - 2m

n = d - 2m

        3*

*Pretend there is a fraction bar between d - 2m and 3

Please help me solve this 200(20)^x&gt;500x+400
s2008m [1.1K]
Hi there!

200(20)^x > 500x + 400

Let's find the critical points of the inequality

200(20^x) = 500x + 400

Now we can divide both sides by 200

(200(20^x))/200 = (500x + 400)/200

20x^x = 5/2 x + 2

There are no critical points.

Thus,

The answer is: No solution

As always, it is my pleasure to help students like you.

A large cube is made up of many small cubes. The volume of the large cube is 7.506×10^5mm^3. The volume of each small cube is 2.
irakobra [83]

Answer:

27 small cubes

Step-by-step explanation:

Given that,

The volume of the large cube is 7.506\times 10^5\ mm^2

The volume of small cube is 2.78\times 10^4\ mm^2

We need to find how many small cubes make up the large cube. Let there are n small cubes. So, it can be calculated as follows :

n=\dfrac{7.506\times 10^5}{2.78\times 10^4}\\\\n=27

So, there are 27 small cubes that make up of the large cube.
