Help me please I have no idea

If x = 745/999, then

999x = 745

1000x - x = 745

This equation tells us that the fractional part of 1000x and x cancel upon subtracting. This means the block of repeating digits must be 3 digits long.

To verify this, suppose we write x = 0.yyy… , where y consists of 3 digits. Then

1000x = y.yyy…

1000x - x = y.yyy… - 0.yyy…

999x = y

x = y/999

which means y = 745.

3 digits

Answer:

solve for k,  k=-1

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable

Answer:

k=-1

Step-by-step explanation:

First step: Distribute

Result: -6-3k-6k=6+3k

Second step: Combine like terms

Result: -6-9k=6+3k

Third step: Add 6 to both sides

Result: -9k=12+3k

Fourth step: Subtract 3k from both sides

Result: -12k=12

Final step: Divide by -12 to both sides

Result/Answer: k=-1

Answer:

Step-by-step explanation:

x1 + x2 divided by 2

y1 + y2 divided by 2

-3 + 4 is 1/2

-4 + 4 is 0

(0.5,0)

i could be wrong but i did it in my head , but the equation is right . just do that in order

Answer:

( 0.5, - 1 )

Step-by-step explanation:

So here is the equation:

x2 + x1 / 2 For the x coordinate

y2 + y1 / 2 For the y coordinate

x2 is 4 and x 1 is -3 whilst y2 is 2 and y1 is -4.

Thus:

4 + -3 / 2 = 0.5 x coordinate

2 + -4 / 2 = -1 y coordinate

So it becomes (0.5, -1)

Answer:

8x³ - 2x² + 3x

Step-by-step explanation:

Given

(3x³ - 4x² + 6x + (- 3x + 2x² + 5x³) ← remove parenthesis

= 3x³ - 4x² + 6x - 3x + 2x² + 5x³ ← collect like terms

= 8x³ - 2x² + 3x

Answer:

x = 2

Step-by-step explanation:

1.) Subtract 8 from both sides.

x + 8 = 10

- 8 -8

2.) Simplify 10 - 8 to 2

x + 8 = 10

-8 -8

Answer:  x = 0; y = 2; z = 5

Step-by-step explanation:

x+2y+z=9

x-y+3z=13

2z=10

==

Start with the last equation:  2z = 10, therefore z = 5 [easy]

Let's rewrite the second equation with 1) z=5, and 2) rearrange to find x:

x-y+3z = 13

x - y +3*5 = 13

x = y-2

Now use the values for x [(y-2)] and y [5] in the first equation:

X+2y+z=9

(y-2) +2y + 5 = 9

3y +3 = 9

3y = 6

y = 2

Now that we have y [2] and z [5], let's use the first equation to solve for x:

x+2y+z=9

x + 4 + 5 = 9

x + 9 = 9

x = 0

====

Try the three values (x=0, y=2, and z=5) in any of the formulas.  The result should/will equal the number shown.

Answer:

supplement = 152°

Step-by-step explanation:

If the complement is 62° , then

angle = 90° - 62° = 28° ( Complementary angles sum to 90° )

Supplementary angles sum to 180° , then supplement of 28° is

180° - 28° = 152°

The control group in the experiment are the classes where the teacher does not greet the students

A control group in an experiment is made up of groups of people that do not receive the experimental treatment.

The purpose of a control group is to allow the researcher study one variable at a time.

Victor is conducting an experiment on if positively greeting children as they enter the classroom reduces problem behaviours.

The experimental treatment here is positively greeting the students.

The group that do not receive this experimental treatment are referred to as the control group.

At the end of the experiment, Victor would compare the behaviours of the students in the control group with the behaviour of those who were part of the experimental group to see if greeting reduced problem behaviours.

Answer:

The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.
