Answer:

  • add x to both sides
  • divide both sides by 4
  • add 20 to both sides
  • divide both sides by 3

Step-by-step explanation:

Your steps in order would be ...

  • add x to both sides
  • divide both sides by 4
  • add 20 to both sides
  • divide both sides by 3

__

Executing these steps, we get ...

  4(3x -20) = 16 . . . . . add x

  3x -20 = 4 . . . . . . . . divide by 4

  3x = 24 . . . . . . . . . . .add 20

  x = 8 . . . . . . . . . . . . . divide by 3, giving the solution

_____

<em>Additional comment</em>

If you were to distribute the 4 first, you would have ...

  12x -80 -x = 16 -x

Now, you can add x and add 80 to get ...

  12x -80 = 16

  12x = 96

Then dividing by 12 gives ...

  x = 8

You will notice that these steps do not match steps available in your list.

Distribute 4 to get 12x-20
Add x to both sides
Add 20 to both sides
Divide both sides by 12

What is the function? F(x)=2x^2-3x+1
olasank [31]

Answer:

To satisfy the hypotheses of the Mean Value Theorem a function must be continuous in the closed interval and differentiable in the open interval.

Step-by-step explanation:

As f(x)=2x3−3x+1 is a polynomial, it is continuous and has continuous derivatives of all orders for all real x, so it certainly satisfies the hypotheses of the theorem.

To find the value of c, calculate the derivative of f(x) and state the equality of the Mean Value Theorem:

dfdx=4x−3

f(b)−f(a)b−a=f'(c)

f(x)x=0=1

f(x)x=2=3

Hence:

3−12=4c−3

and c=1.

To make a specific orange color, a painter uses 14 of a can of red paint and 12 of a can of yellow paint. Fill in each statement
Otrada [13]

Answer:  For every 1 can of red paint, the number of yellow paints used by the painter is \frac{6}{7} and

There are approximately 29 cans of yellow paints for 34 cans of red paints.

Step-by-step explanation:

Since we have given that

Number of cans of red paint = 14

Number of cans of yellow paint = 12

According to question, we have to find that for every 1 can of red paint the painter uses what number of yellow paints;

Since the ratio of red paint to yellow paint is given by

14:12\\\\7:6\\\\1:\frac{6}{7}

So, for every 1 can of red paint, the number of yellow paints used by the painter is \frac{6}{7}

Similarly,

If Number of can of red paint is used = 34

So, Number of cans of yellow paint will be

\frac{6}{7}\times 34\\\\=\frac{6\times 34}{7}\\\\=29\ approx.

Hence, there are approximately 29 cans of yellow paints for 34 cans of red paints.
