4(x-2)/5 = 20

(Yes that’s a fraction)

Solving for x

Answers

Answer:

x=27

Step-by-step explanation:

Step 1: Multiply both sides by 5.

4(x−2)

5=20

(4(x−2)*(5)*(5)=(20)*(5)

4(x−2)=100

Step 2: Simplify both sides of the equation.

4x−8=100

Step 3: Add 8 to both sides.

4x−8+8=100+8

4x=108

Step 4: Divide both sides by 4.

4x/4=108/4

x=27

Step-by-step explanation:

(x-2)/5 = 5

(x-2) = 25

x = 27

If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side

Answers

Answer:

[tex]x=9, AB=BC=AC=35[/tex]

Step-by-step explanation:

Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that [tex]AB=BC=AC[/tex]. We are given the lengths of all 3 sides in terms of [tex]x[/tex], but we only need to set two of them equal to each other to solve for [tex]x[/tex]. Let's use [tex]AB[/tex] and [tex]BC[/tex] to solve for [tex]x[/tex]. We know that [tex]AB=BC[/tex], [tex]AB=2x+17[/tex], and [tex]BC=6x-19[/tex]. Therefore, we can write the following equation to solve for

[tex]AB=BC\\2x+17=6x-19[/tex] (Substitute given values into equation)

Solving for [tex]x[/tex], we get:

[tex]2x+17=6x-19\\2x+17-17=6x-19-17[/tex] (Subtract [tex]17[/tex] from both sides of the equation to isolate constants)

[tex]2x=6x-36[/tex] (Simplify)

[tex]2x-6x=6x-36-6x[/tex] (Subtract [tex]6x[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]-4x=-36[/tex] (Simplify)

[tex]\frac{-4x}{-4}=\frac{-36}{-4}[/tex] (Divide both sides of the equation by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=9[/tex] (Simplify)

Therefore, [tex]AB=2x+17=2*9+17=18+17=35[/tex], and [tex]AB=BC=AC=35[/tex]. Hope this helps!

6x=-12

x=-2

-4+4y=-16

4y=-12

y=-3

Answer:

x=-2

y=-3

Step-by-step explanation:

2x=-4y-16 subtract 4y and move to the other side of the equation

x=-2y-8 divide by 2 to isolate x

-2(-2y-8)+2y=-2 plug x into the second equation

4y+16+2y=-2 distribute

6y=-18 combine the Y's and subtract 16 to the other side

y=-3 divide both sides by 6

2x+4(-3)=-16 plug the y value into the first equation to find x

2x-12=-16 distribute (multiply)

2x=-4 add 12 to both sides

x=-2 divide by 2 to get the x value

The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.

Answers

Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

What is the perimeter of a triangle?

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.
