The soultion of the given equation 1/4x - 3/4 = 7/x for x is 9.

According to the given question.

We have an equation 1/4x - 3/4 = 7/x.

As we know that, as we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.

Therefore, the solution of the equation 1/4x - 3/4 = 7/x is given by

1/4x - 3/4 = 7/x

⇒ 1/4x - 7/x -3/4 = 0

⇒ 1- 28/4x = 3/4

⇒ 27/4x = 3/4

⇒ 27 = (3/4)(4x)

⇒ 27 = 3x

⇒ 27/3 = x

⇒ x = 9

Hence, the soultion of the given equation 1/4x - 3/4 = 7/x for x is 9.

Answer:

10 feet

Step-by-step explanation:

18 × 2 = 36

56 - 36 = 20

20 ÷ 2 = 10

To check work, add all lengths together. 4 sides. 18 + 18 + 10 + 10 = 56

4(5x-3)=48 <img src="https://tex.z-dn.net/?f=4%285x%20-%203%29%3D%2048" id="TexFormula1" title="4(5x - 3)= 48" alt="4(5x - 3)

Hello, My Dear Friend!

Solution for $4(5x-3)=48$ equation:

Simplifying:
 $4(5x + -3) = 48$ 

Reorder the terms:
 $4(-3 + 5x) = 48$
$(-3 * 4 + 5x * 4) = 48$
$(-12 + 20x) = 48$ 

Solving:
 $-12 + 20x = 48$ 

Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12' to each side of the equation.
 $-12 + 12 + 20x = 48 + 12$ 

Combine like terms: $-12 + 12 = 0$ $0 + 20x = 48 + 12$
$20x = 48 + 12$ 

Combine like terms: $48 + 12 = 60$
$20x = 60$ 

Divide each side by '20'.
 $x = 3$ 

Simplifying:
 $x = 3$ 

Therefore, THAT is The Answer!^^^

=====> x = 3 <=====

6. Identify the slope of a line parallel to the given line. y- 4 = + (x + 8)

AleksAgata [21]

Answer: slope = 1

Step-by-step explanation:

For two lines to be parallel then they have the same slope , if the slope of line 1 is M1 and then slope of line 2 is M2 , if they are parallel then M1 = M2.

Given; y- 4 = + (x + 8)

Make y the subject of the formula , so that the equation can be in slope - intercept form , that is in the form y = mx + c , where m is the slope and c is the y - intercept.

y - 4 = x + 8

Add 4 to both sides

y = x + 8 +4

y = x + 12

since the coefficient of x is 1 , this means that the slope is 1 , any line that will be parallel to this line must have a slope which is 1
