Answer:

[tex]k=13\text{ or } k=-7[/tex]

Step-by-step explanation:

So we have the equation:

[tex]|-3+k|=10[/tex]

Definition of Absolute Value:

[tex]-3+k=10\text{ or } -3+k=-10[/tex]

Add 3 to both sides for both equations:

[tex]k=13\text{ or } k=-7[/tex]

And we're done!

Answer:

K=13

Step-by-step explanation:

|-3+k|=10 this is an equation with absolute  value

add 3 on both sides

k=13

Answer:

[tex]\frac{3,25}{5}=0,65 \\[/tex] for brand x for 1 fluid ounces

[tex]\frac{6}{8}=0,75[/tex] for brand y

0,75-0,65=0,1

Brand x costs $0,1 less

Step-by-step explanation:

Answer:

0.10 less

Step-by-step explanation:

First you need to find how much for one fluid ounce, so for Brand X you would divide 3.25 by 5 to get 0.65 and for Brand Y 6.00 divided by 8 to get 0.75. Now you know how much for 1 ounce of each brand so next you just have to subtract 0.65 (Brand X) from 0.75 (Brand Y) to get that Brand X costs $0.10 less than brand Y.

The complete question is contained in the image.

The distance between points [tex]A(x_1,y_1)[/tex] and [tex]B(x_2,y_2)[/tex] in the coordinate plane is given as:

[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Point D is at (7, 0) and E at (0, -2) hence the distance between the two points is:

[tex]|DE|=\sqrt{(0-7)^2+(-2-0)^2}=\sqrt{49+4}=\sqrt{53}=7.28[/tex]

Point R is at (-7, -7) and S at (3, -3) hence the distance between the two points is:

[tex]|RS|=\sqrt{(3-(-7))^2+(-3-(-7))^2}=\sqrt{100+16}=\sqrt{116}=10.77[/tex]

Since |RS| ≠ |DE|, therefore they are not congruent

The scale factor of the drawing of the house given the scale of the drawing is 1cm : 0.29m.

A scale drawing is a smaller image of a larger image or object. The scale drawing is usually reduced at a constant dimension.

The scale factor is the ratio of the dimension of the scale drawing to the original object. The scale factor is the measurement used to convert the larger image into a smaller version of the original object.

The scale factor is usually written in this format - 1, a colon (:), then the matching length on the original image. e.g. 1 : 10

The scale factor of the drawing = original dimensions/dimensions of the scale drawing

2 / 7 = 0.29

Answer: 0.2

Step-by-step explanation:

Answer:

the answer is -0.5.

Step-by-step explanation: First subtract 17 from 15 to know what u need to get. Know that u get -2, we have to figure out what to do to get -2 out of 4. First to get positive 2, multiply by 0.5, than since we need to get negative 2, add a negative in front. Hence, the answer is -0.5 .

your equation would read

4•x+17=15

so 4 times what plus 17 is 15?

4•-0.5+17=15

Step-by-step explanation:

Adding a whole to a fraction

Rewrite the whole as a fraction using  5  as the denominator :

        4       4 • 5

   4 =  —  =  —-   = 5

        1          5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Given that:

James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3 .

To find:

The equation that can be used to solve for zach's age.

Solution:

Let the age of zach be Z.

Zach added 8 to his age = Z+8

And multiplied this sum by 3 = 3(Z+8)

James is 6 times older than his friend Zach = 6Z

Now,

[tex]6Z=3(Z+8)[/tex]

[tex]6Z-3Z=24[/tex]

[tex]3Z=24[/tex]

Divide both sides by 3.

[tex]Z=8[/tex]

Therefore, the required equation is [tex]6Z=3(Z+8)[/tex] is age of zach is 8 years.

Answer:

[C] -1

Explanation:

3 - 2x = 5

Subtract 3 from both sides

3 - 2x - 3 = 5 - 3

Simplify

-2x = 2

Divide both sides by -2

-2x / -2 = 2 / -2

x = -1

$57

Step-by-step explanation:

1h = $39

so the first hour costs $39

2.5h -1h =1.5h=90mins

0.20x90=18

so 1h30mins after the initial 1h cost $18

so all together it costs $18+$39= $57

12 +g=32

Step-by-step explanation:

32 chapters

12 chapters read

-------

20 chapters must read

=>

12+g =32

g=32 - 12

g=20

The equation that best represents the situation will be 12 + 8c = 32

Based on the information, Etu has read 12 of the 32 chapters in his assigned book and he plans to finish the book by reading c chapters each for 8 days until the book is due.

Therefore, the equation that best represents the situation based on the information will be 12 + 8c = 32

[tex]\bf Step-by-step~explanation:[/tex]

We are given that BA is perpendicular to BD, so that must mean that m∠ABD is a right angle, or 90º. This means: (8x - 10) + (4x + 52) = 90º, since both of the angles add up to become a right angle. We have to solve for x in order to find m∠CBD.

PART 1

[tex]\bf Step~1:[/tex]

Equation: (8x - 10) + (4x + 52) = 90

Let's add the like values together first.

[tex]\bf 8x+4x=12x\\-10+52 = 42[/tex]

[tex]\bf 12x+42=90[/tex]

[tex]\bf Step~2:[/tex]

Let's subtract 42 from both sides of the equation to isolate the variable we are solving for, x. Our goal is to isolate it completely to get a value that is equal to x.

[tex]\bf12x+42(-42)=90(=42)\\12x=48[/tex]

[tex]\bf Step~3:[/tex]

Divide both sides by 12 to get our final answer for x.

[tex]\bf\frac{12x}{12} =x\\\\\frac{48}{12}= 4\\\\x=4[/tex]

PART 2

Now that we have x, we simply plug it into our equation for m∠CBD.

[tex]\bf Step~1:[/tex]

[tex]\bf4x+52\\4(4)+52[/tex]

[tex]\bf Step~2:[/tex]

Multiply 4 and add 52.

[tex]\bf 4*4=16\\16+52=68[/tex]

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(3, 11) and B(7,3)

The midpoint is

[tex]M = ( \frac{3 + 7}{2} \: , \: \frac{11 + 3}{2} ) \\ = ( \frac{10}{2} \: , \: \frac{14}{2} )[/tex]
