Answer: m=−3

Step-by-step explanation: −40−2(3m+1/2)=7m−2

−40+(−2)(3m)+(−2)(1/2)=7m+−2

−40+−6m+−1=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

−6m−41−7m=7m−2−7m

−13m−41+41=−2+41

−13m/−13=39/−13

m=−3

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

  graph attached

Step-by-step explanation:

The attachment is a graph that shows Beyonce is correct.

__

By solving the system the two ways that she has, Beyonce has already shown her solution is correct by substitution. After finding the value of one variable, she substituted that into the system of equations to find the other variable. She did this for each of the variables.

Answer:

59.92

Step-by-step explanation:

58.53 + 1.39 = 59.92

Answer:

$59.92

Step-by-step explanation:

Reduced means subtracted. So if you add $1.39 + $58.53 it equals $59.92 which is the original price.

Answer:

x = 5

Step-by-step explanation:

set JN and NL equal to each other...

14x – 17 = 3x + 38

11x = 55

x = 5

1. You could plug this into the calculator as either 70% of 156.33 or 0.7 × 156.33, but either way you know the discount is going to be $109.43

2. We got the discount, so all you have to do is subtract it from the original. 156.33 - 109.43 = $46.90 which is the sale price! I hope this helps

Answer:

No of these answers has a slope of  [tex]\frac{-3}{5}[/tex] . My guess is B becasue its close to [tex]\frac{-3}{5}[/tex] unless the 5 is supposed to be negative

Step-by-step explanation:

You have to use the slope formula [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

([tex]x_{1}[/tex],[tex]y_{1}[/tex]), ([tex]x_{2}[/tex],[tex]y_{2}[/tex])

(4, 0), (-2, 10)   [tex]\frac{10 - 0 }{-2 - 4 }= \frac{10}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{5}{3}[/tex]

(10, -2), (0, 4)  [tex]\frac{4 - -2 }{0- 10 }= \frac{6}{-10}[/tex] you have to simplfy, the answer will be [tex]\frac{3}{-5}[/tex]

 (4, 2), (10, 4)  [tex]\frac{4 - 2 }{10 - 4 }= \frac{2}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{1}{3}[/tex]

 (-4, -10),(0, -2) [tex]\frac{{-2- -10} }{0 - -4 }= \frac{8}{4}[/tex] you have to simplfy, the answer will be [tex]\frac{2}{1} =2[/tex]

Answer:

9y-3y=6y is equivalent to 9y – 3y.

The radius of the button will be 14 millimetres.

The radius of the circler is defined as the distance from the centre of the circle to the outermost surface of the circle. The diameter of the circle is the distance between the two points on the surface of a circle passing through the centre of the circle.

Given that the diameter of the circle is 28 millimetres. the radius of the circle is calculated as,

Radius = Diameter / 2

Radius = 24 / 2

Radius = 12 millimetres

Therefore, the radius of the button will be 14 millimetres.

Answer: this solution cant be solved

Step-by-step explanation:

Answer:

4.25 m

Step-by-step explanation:

Resolvemos esta pregunta usando la fórmula:

Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo

Sombra del hombre = 3.50 m

Altura de un hombre = 1.75 m

Sombra del palo = 8.50 m

Altura del palo = x

Por lo tanto:

1.75 / 3.5 = x / 8.5

Cruz multiplicar

1.75 × 8.5 = 3.5 × x

14.875 = 3.5x

x = 14.875 / 3.5

x = 4.25 metros

Por tanto, la altura del palo = 4.25 m

Answer:

Slope = 1/2

Step-by-step explanation:

Formula for getting slope using 2 points...

(y2 - y1) / (x2 - x1)

= (3 - 0) / (6 - 0)

= 3 / 6

= 1/2

So...

Slope is 1/2

Hope this helps :)

Let me know if there are any mistakes!!

Answer:  The slope is   1/2

Step-by-step explanation:

When a line passes through the origin the equation of the line will be represented in the form    y= kx   where k is the slope.

To to find k you will need to divide both sides by x.

y = kx

y/x = kx/x

  k = y/x  

This means that to find k, you will need to divide the y coordinate of the point by the x coordinate.  

  k = 3/6

K = 1/2

Answer:

800 bacteria

Step-by-step explanation:

Over here, we have exponential growth.

So we have 50 bacteria

Every 30 minutes, it doubles in size

In 120 minutes, there are four 30 minutes.

So you do 50 * 2 * 2 * 2 * 2

Do that out and you get 800

Answer: a=−3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

a−2+3=−2

a+−2+3=−2

(a)+(−2+3)=−2(Combine Like Terms)

a+1=−2

a+1=−2

Step 2: Subtract 1 from both sides.

a+1−1=−2−1

a=−3

Answer:

a=-1

Step-by-step explanation:

move -2 and 3 to the right side to have the variable by itself and then just add them together.

a = -2+3-2

a= -4+3

a= -1

Answer:

The value of x = 14/3

Step-by-step explanation:

Given the equation

[tex]3x-5 = 9[/tex]

Add 5 to both sides

[tex]3x-5+5=9+5[/tex]

Simplify

[tex]3x=14[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{14}{3}[/tex]

Simplify

[tex]x=\frac{14}{3}[/tex]

Therefore, the value of x = 14/3

Note: It seems you may have missed entering the correct answer choice as the value of x = 14/3 is not mentioned in your answer choices.
