Answer:

<R = 30

LM = 6 sqrt(3)

Step-by-step explanation:

Since the figures are congruent

<R = < L

<S = <M

< T = <N

RS = LM

ST = MN

RT = LN

<L = 30 so <R = 30

RS = 6 sqrt(3) so LM = 6 sqrt(3)

-50= 6a+28 please help

Answers

-50 = 6a + 28

Subtract 28 from both sides.
-50 -28 = 6a + 28 - 28
-78 = 6a

Divide both sides by 6.
-78/6 = 6*a/6
-78/6 = a

-13 = a

Answer:

a=-13

Step-by-step explanation:

-50=6a+28

isolate the a

-50-6a=28

-6a=28+50

-6a=78

divide both sides by -6

a=-13

Answers

The solution to the equation [tex]\frac{-4}{1(a-4)} = \frac{4}{7(a-3)}[/tex] is a = 3.125

The given equation is:

[tex]\frac{-4}{1(a-4)} = \frac{4}{7(a-3)}[/tex]

Cross multiply:

[tex]-4(7)(a-3) = 4(a-4)[/tex]

Divide both sides by 4

[tex]\frac{-4(7)(a-3)}{4} = \frac{4(a-4)}{4} \\-7(a-3) = a - 4[/tex]

Expand the bracket using the distributive rule

-7a + 21  =  a  -  4

Collect like terms

a  +  7a   =  21  +  4

Simplify the arithmetic

8a   =  25

Divide both sides by 8

[tex]\frac{8a}{8} = \frac{25}{8}\\a = \frac{25}{8}\\a = 3.125[/tex]

5/6x -4 =6
how do you solve for x?

Answers

Answer:

x=12

Step-by-step explanation:

so first you add 4 to both sides:

[tex]\frac{5}{6}[/tex]x - 4 = 6

  +4    +4

=  [tex]\frac{5}{6}[/tex]x = 10

now you divide 10 by [tex]\frac{5}{6}[/tex] or you can flip the fraction upside down and multiply it by 10:

[tex]\frac{6}{5}[/tex] × 10 = [tex]\frac{60}{5}[/tex] = 12

x = 12

Solve for x:

Add 4 to both sides-

5/6x - 4 = 6

+4 +4

5/6x = 10

Now divide 5/6 on both sides-

(5/6)/(5/6) = 10/(5/6)

x = 12

7x + 3x - 18 = 6(x + 3)

Answers

Answer:

x=9, therefore 72=72

Step-by-step explanation:

I just distributed.

Answer:

x = 9

Step-by-step explanation:

7x + 3x - 18 = 6(x + 3) ← distribute parenthesis by 6

10x - 18 = 6x + 18 ( subtract 6x from both sides )

4x - 18 = 18 ( add 18 to both sides )

4x = 36 ( divide both sides by 4 )

x = 9

x = 120

Step-by-step explanation:

Assuming you require to find the value of x

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

140 + 150 + 90 + x + 130 + 90 = 720 , that is

x + 600 = 720 ( subtract 600 from both sides )

x = 120

The answer is X=120 :)

How do I get the x and y intercepts to graph this equation?

Y=-1/2x-3

Answers

Answer: x intercept is (-6,0) and y intercept is (0,-3)

Step-by-step explanation: the y intercept is when x=0. the x intercept is when y=0.

to solve this for the y intercept, we set x=0 in the equation y=-1/2x-3. so it would be y=-1/2(0)-3 therefore y= 0-3 and y=-3. the y intercept is (0,-3)

to solve for the x intercept, we set y=0. we plug it into the equation y=-1/2x-3 so 0=-1/2x - 3. this means we can change the sign of -1/2x from negative to positive and move it to the other side. so 1/2x=-3 to solve for x, we divide both sides by 1/2 so x=-6. so the x intercept is (-6,0)

4x + 6 = 2(2x +3) is an example of what type of equation?

Answers

Answer:

Simplifying

4x + -6 = 2(2x + 3)

Reorder the terms:

-6 + 4x = 2(2x + 3)

Reorder the terms:

-6 + 4x = 2(3 + 2x)

-6 + 4x = (3 * 2 + 2x * 2)

-6 + 4x = (6 + 4x)

Add '-4x' to each side of the equation.

-6 + 4x + -4x = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-6 + 0 = 6 + 4x + -4x

-6 = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-6 = 6 + 0

-6 = 6

Solving

-6 = 6

Answer:

The speed of light is exactly 299,792,458 m/s because that is how a meter is defined. A meter is defined as the distance light travels in 1/299792458 seconds in vacuum. Why was this particular number chosen? To keep the definition of meter consistent with the old standard which was an actual physical bar. The length of this bar was arbitrary though.
