Step-by-step explanation:

<ABC and <CBD are supplementary, meaning when added together they equal 180 degrees. So that means 5x + 2x + 5 = 180. Add 5x and 2x together to make 7x, so you are left with 7x+5 = 180. Subtract 5 from both sides to get 7x = 175. Divide 7 on both sides to get x by itself, so you are left with the result x = 25, proving that x does equal 25 degrees.

The solution for the equation will be 37 a² - 55 a + 30

What is Linear Equation in 2 variables?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Given data ,

g ( x ) = x² - 5 x + 8

To solve for g ( 5 a - 2 ) + 3 g ( 2 a ) , substitute for the value of x

Therefore ,

g ( 5 a - 2 ) = ( 5 a - 2 )² - 5 ( 5 a - 2 ) + 8

                  = ( 25 a² + 4 - 20 a ) - 25 a + 10 + 8

                  = 25 a² - 45 a + 22

3 g ( 2 a ) = 3 [ (2 a )² - 10 a + 8 ]

                = 3 [ 4 a² - 10 a + 8 ]

                = 12 a² - 10 a + 8

And , g ( 5 a - 2 ) + 3 g ( 2 a ) = 25 a² - 45 a + 22 + ( 12 a² - 10 a + 8 )

                                               = 37 a² - 55 a + 30

Hence , the value of the equation will be 37 a² - 55 a + 30

Answer:

Answer B because $15 for 180 lbs is way more than 300 lbs for $24 dollars.

Step-by-step explanation:

Let's see what to do buddy...

_________________________________

The sum of the angles of each n-sided figure is found in the following equation :

[tex](n - 2) \times 180 [/tex]

The question's figure is 5-sindes figure

so the sum the angles equal :

[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]

So we have :

[tex]90 + 107 + 144 + 138 + x = 54 0 \\ [/tex]

[tex]479 + x = 540[/tex]

Subtract the sides of the equation minus 479

[tex]x = 540 - 479[/tex]

[tex]x = 61[/tex]

And we're done.

Thanks for watching buddy good luck.

Answer:

(-1373)

Step-by-step explanation:

a = 1st term = -13

Common difference = d = 2nd term - 1st term

                            d = -33 - (-13) = -33 + 13

                             d = -20

n = 69

nth term = a + (n-1)d

69th term = (-13) + 68 * (-20)

                 = -13 - 1360

                =  - 1373

Answer:

y = 2x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 5 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (- 3, 1) into the partial equation

1 = - 6 + c ⇒ c = 1 + 6 = 7

y = 2x + 7 ← equation of parallel line

Distance between the police station and the fire station be 4 miles

Step-by-step explanation:

Let distance between the police station and the fire station be x miles.

The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station.

Distance between the library and the police station [tex]=2x-3[/tex]

Also, distance between the library and the police station is 5 miles.

[tex]2x-3=5\\2x=3+5\\2x=8\\x=\frac{8}{2}\\ x=4\,\,miles[/tex]

Answer:

-2a + 22 = 22

Step-by-step explanation:

Distribute the 3 to both terms in (a + 4) and -5 to both terms in (a – 2) to get 3a + 12 – 5a + 10 = 22. Simplify to get -2a + 22 = 22.

Answer:

Absolute value equation is:

|L - 72| ≤ 0.05

Solution is 71.05 ≤ L ≤ 72.5

Step-by-step explanation:

We are told that the length (l) of the boards that the company received varies from a maximum length of 0.05 inches longer than 6 feet to a minimum length of 0.05 inches shorter than 6 feet.

From conversions, 1 ft gives 12 inches. Thus, converting the 6 ft to inches gives us; 6 × 12 = 72 inches

This means that minimum value of L is 72 - 0.05 and maximum is 72 + 0.05.

Thus,the absolute value equation is;

|L - 72| ≤ 0.05

Solving this gives;

L - 72 ≤ 0.05 and -(L - 72) ≤ 0.05

This gives;

L ≤ 72 + 0.05 and -L + 72 ≤ 0.05

L ≤ 72.05 and 72 - 0.5 ≤ L

L ≤ 72.05 and 71.05 ≤ L

Step-by-step explanation:

I find it easier to make these proper fractions into improper fractions.

To make proper to improper, you multiply the denominator with the whole number and then add the product with the numerator.

Answer:

His total commission was: $2,960

Step-by-step explanation:

The commissions that Michael Fenton earns by selling plumbing supplies to contractors has three levels:

On the first $15,000 in sales, he earns 3%

On the next $15,000 in sales, he earns 5%

Over $30,000 in sales, he earns 8%.

Last month he sold $52,000 worth of plumbing supplies. His commissions will be calculated according to the levels reached:

The first $15,000 gave him 3%*15,000=0.03*15,000=$450

From the $52,000 sales, there remains $52,000 - $15,000 = $37,000 for the next levels.

The next $15,000 gave him 5%*15,000=0.05*15,000=$750

Now $37,000 - $15,000 = $22,000 remain for the last level.

Michael earned 8% of $22,000 = 0.08*22,000 = $1,760

His total commission was: $450 + $750 + $1,760 = $2,960

Answer:

Step-by-step explanation:

[tex]3(x + 1) = −2(x − 1) + 6[/tex]

Expand the terms in the bracket and simplify

That's

[tex]3x + 3 = - 2x + 2 + 6 \\ 3x + 3 = - 2x + 8[/tex]

Add 2x to both sides of the equation

[tex]3x + 2x + 3 = 2x - 2x + 8 \\ 5x + 3 = 8[/tex]

Subtract 3 from both sides of the equation

[tex]5x + 3 - 3 = 8 - 3 \\ 5x = 5[/tex]

Divide both sides by 5

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

We have the final answer as
