Answer:

The measure of x is 23 degrees

Step-by-step explanation:

Here, given the values of the angles of a polygon and the total of these angles, we want to find the value of the variable x attached to these angles;

Mathematically;

85 + 5x + 5x + 5x + 5 + 5x -10 = 540

85 + 5 -10 + 5x + 5x + 5x + 5x = 540

80 + 20x = 540

20x = 540-80

20x = 460

x = 460/20

x = 23 degrees

Answer: answers are (-7m - 8 = m -4) and m - 4 = -7m -8. Hope this helps :)

Step-by-step explanation:

The expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given expression is -2m - 5m - 8 = 3 + (-7) + m. The given expression will be solved as:-

-2m - 5m - 8 = 3 + (-7) + m

-7m - 8 = -4 + m

We can also write the same equation in different ways:-

(-8 - 7m = -4 + m)

(m - 4 = -7m - 8)

Therefore, the expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).

Answer:

Step-by-step explanation:

The midpoint of the final image is  (2, 1.5).

Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes both two-dimension and three-dimension.

Segment JK has endpoints J(2,4) and K(6,2).

You dilate the segment using a dilation centered at the origin with a scale factor of 1/2 and then reflect the image on the x-axis.

The  co-ordinate of the final image is;

[tex]\rm J' = Scale \ factor (J) = \dfrac{1}{2} (2, \ 4) = (1, \ 2)\\\\K' = Scale \ factor (K) = \dfrac{1}{2} (6, \ 2) = (3, \ 1)\\[/tex]

The midpoint of the final image is;

[tex]\rm Midpoint \ of \ J'= \left (\dfrac{1+3}{2} \right )= \left (\dfrac{4}{2} \right )=2\\\\ Midpoint \ of \ K'= \left (\dfrac{2+1}{2} \right )= \left (\dfrac{3}{2} \right )=1.5[/tex]

Hence, the midpoint of the final image is  (2, 1.5).

Answer:

How do you explain a linear equation?

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b. "Linear equation."

Step-by-step explanation:

In mathematics, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.

Answer:

n = -7

Step-by-step explanation:

Add '-24' to each side of the equation.

24 + -24 + 6n = -18 + -24

Combine like terms: 24 + -24 = 0

0 + 6n = -18 + -24

6n = -18 + -24

Combine like terms: -18 + -24 = -42

6n = -42

Divide each side by '6'.

n = -7

Simplifying

n = -7

Answer: Record keeping

Step-by-step explanation:

A person's net worth is calculated as the total assets they own minus the total liabilities they owe. As such it will be very important to keep records so that you know what you own as well its value as well as what you owe as well.

Taxes are no different. The better the records you keep are, the more accurate your tax payments will be. Without proper records you could overpay taxes which would mean you lose money or you could underpay taxes which is a crime.

Answer:

x = - 12

Step-by-step explanation:

Given

x - 17 = - 29 ( add 17 to both sides )

x = - 12

Answer:

x=12

Step-by-step explanation:

when performing x-17=-29, you first have to do the inverse of -17 in order to isolate x. Therefore, your would +17 to the left side of the equation (x-17) resulting in only the letter x being left on that side. Then you would have to add the 17 to the other side of the equation resulting in x=-29+17 which will then result in x=12.

Answer:

Issac worked 24.4 hrs, Ruby worked 31.4 hrs, and George worked 94.2 hours

Step-by-step explanation:

x= hours worked

Issac= x Ruby= (x+7) George= 3(x+7)

x+(x+7)+3(x+7) = 150 [distribute 3 to (x+7)]

x+(x+7)+(3x+21) = 150 [add from left to right]

5x+28 = 150 [subtract 28 from both sides]

5x = 122 [divide both sides by 5]

x=24.4

Now plug the x value back into Issac, Ruby, and George's equations:

Issac=x=24.4

Ruby=x+7=31.4

George=3(x+7)=94.2

Double check by adding all their work hours together

24.4+31.4+94.2=150!!

Answer:

50 degrees.

Step-by-step explanation:

Angle FGE = [tex]180-(7x+18)[/tex] because angles on a straight line add up to 180 degrees.

Angle EFG = [tex]180-38-(180-(7x+18))=6x-10[/tex] (Angles in a triangle add up to 180)

[tex]180-38-\left(-7x+162\right)=6x-10[/tex]

[tex]180-38+7x-162=6x-10[/tex]

[tex]7x-20=6x-10[/tex]

Add 20 to both sides:

[tex]7x-20+20=6x-10+20[/tex]

[tex]7x=6x+10[/tex]

Subtract 6x from both sides:

[tex]7x-6x=6x+10-6x[/tex]

[tex]x=10[/tex]

Angle [tex]EFG=6x-10=6(10)-10=60-10=50[/tex]

Answer:

(-3, 4)

Step-by-step explanation:

hey there,

< From the first equation, let's find x.

x + 3y = 9

x = 9-3y    (I hope you understand how that works )

Next, we can substitute our equation that equals to x into the second equation.

2x + y = -2

2(9-3y) + y = -2     (I substituted "x" in "2x" with (9-3y))

Now, let's solve.

2(9-3y) + y = -2

18 - 6y + y = -2

-5y = -20

y = 4

Now that we have found what y is equal to, we can find x too. In the beginning we found that x = 9-3y so x = 9-3(4) = -3 >

Question:

six less than a number w

Answer:

w-6

a+b=90°

a=b+44°

b+44°+b=90°

2b+44°=90°

2b=90°-44°

2b=46°

b=23°

a=23°+44°

a=67°

The measure of each angle is 23° and 67°.

Angle is defined as the figure formed by the meeting of two lines or rays at a common point.

Complementary angles are those angle whose angle measures sum up to 90°.

Given that two angles are complementary and one of the angle's measure is 44° less than the measure of other one.

Let x be the measure of first angle.

Then x - 44 is the measure of the other angle.

x + (x - 44) = 90°

2x - 44 = 90

2x = 90 + 44

2x = 134

x = 134 / 2

x = 67

One of the measure of angle is 67°.

Measure of other angle = x - 44 = 67 - 44 = 23°

Hence the angle measures are 23° and 67°.
