9x-4=3x-28 step by step

Answers

Answer:

Step-by-step explanation:

9x-4= 3x-28

We simplify the equation to the form, which is simple to understand  

9x-4=3x-28

We move all terms containing x to the left and all other terms to the right.  

+9x-3x=-28+4

We simplify left and right side of the equation.  

+6x=-24

We divide both sides of the equation by 6 to get x.  

x=-4

A square of an unknown side length x inches has one side length increased by 4 inches and the other increased
by 7 inches

(a) If the original square is shown below with side lengths marked as x, label the second diagram to represent the new rectangle constructed by increasing the sides as described above.

Answers

Answer:

Length of new rectangle = (x + 7) inches

Width of new rectangle = (x + 4) inches

Step-by-step explanation:

A rectangle is a quadrilateral that has opposite sides to be parallel and equal. While a square has all its sides to be equal.

Given that: the square has unknown side length x inches.

Increasing one of its length by 4 inches = (x + 4) inches

Increasing the other by 7 inches = (x + 7) inches.

The new lengths results to a rectangle with length (x + 7) inches, and a width of (x + 4) inches.

the label diagram to represent the new rectangle is shown in the diagram attached to this answer.

Answer:

A = [tex]\frac{5}{6}[/tex]

Step-by-step explanation:

From the number line attached in the figure,

Number of small parts from number 0 to 1 on the given number line = 6

A is the point which lies at 5th part from 0.

Each small part represents the fraction = [tex]\frac{1}{6}[/tex]

Therefore, A represents the fraction = [tex]5\times \frac{1}{6}[/tex]

                                                             = [tex]\frac{5}{6}[/tex]

So A = [tex]\frac{5}{6}[/tex] will be the answer.
