pls solve this fast

Answers

Answer 1

Answer:

x = 20

Step-by-step explanation:

3x = 40 + x

-x           -x

2x = 40

Divide both sides by 2

x = 40/2

x = 20

What is the answer to this question.

Answers

I don't think I have ever seen a question worded with "partitions AB in the ratio".

But if it means what I think it means, a figure could explain it better.

o Here is B(2,0)

o Here is P(-1,-2.4)

Here is A(-3,-4)o

There is a straight line from the bottom point (A) to the top point (B) and its equation is y=0.8x-1.6

The point (-1, -2.4) lies on the line from A to B, but not in the center.

If you find the distance from A to P, then find the distance from P to B, you can make a ratio of the two lengths.

AP = sqrt[(-1-(-3))2+(-2.4-(-4))2] = sqrt[22+1.62] = sqrt[6.56] = 2.561
PB = sqrt[(-1-2)2+(-2.4-0)2]=sqrt[(-3)2+(-2.4)2] = sqrt[14.76] = 3.842

So the two parts are in the ratio 2.561 : 3.842 (AP : PB) or 2.561/3.842 = 0.66658 = 2/3 (approx)

The point P partitions AB into two segments with ratio 2/3

Not sure if that what you mean because there isn’t a lot of context but hope that helped, have a great day

Subtract: 3.8 - 2.923. Explain in your own words how you would solve this, in detail, from start to finish.

Answers

Given:

3.8 - 2.923

To find:

The subtraction.

Solution:

We have,

3.8 - 2.923

It can be written as

3.800 - 2.923

After subtraction, we get

3 . 8 0 0

-2 . 9 2 3

------------------

0 . 8 7 7

-----------------

So, 3.800 - 2.923 = 0.877.

Therefore, the value of 3.800 - 2.923 is 0.877.

This month the Middle School Media newspaper has 25 pages. Twenty-five schools order the paper for each of their students. Each of the schools has 25 classrooms with 25 students in each classroom. What expression with an exponent shows the total number of pages in all of the newspapers?

Answers

Answer:

25^4

Step-by-step explanation:

Here, we want to find the expression that shows the total number of pages in all of the news papers

Number of pages per book = 25

Number of schools is 25

Number of classrooms is 25

Number of students per classroom is 25

Now; the number of students in each school

is 25 * 25

Number of students in all of the school will be;

25 * 25 * 25

So the number of pages in all of the schools will be;

25 * 25 * 25 * 25 = 25^4

I’m not sure but m 5 is 97 and m 8 is 83

Answer:

Angle 8 = 83

Angle 5 = 180 -83 = 97

Step-by-step explanation:

Check: Just an example to check using Co- interior angles

Angle 2 + Angle 5 =  180 degrees

                83 +97  = 180 degrees

       180 degrees = 180 degrees

Therefore Angle 5 = 97 degrees and Angle 8 = 83 degrees

Solve the following:
4x-3=2x+7

Answers

Answer:

= 5

Step-by-step explanation:

Add 3 to both sides of the equation 4 − 3 = 2 + 7 4x-3=2x+7 4x−3=2x+7 4 − 3 + 3 = 2 + 7 + 3

Simplify Add the numbers Add the numbers 4 = 2 + 1 0

Subtract 2 2x 2x from both sides of the equation 4 = 2 + 1 0 4x=2x+10 4x=2x+10 4 − 2 = 2 + 1 0 − 2

Simplify Combine like terms Combine like terms 2 = 1 0

Divide both sides of the equation by the same term 2 = 1 0 2x=10 2x=10 2 2 = 1 0

Simplify Cancel terms that are in both the numerator and denominator Divide the numbers = 5

Answers

Answer:

15km/cm

Step-by-step explanation:

All you do is divide 45 by three to determine your scale

Answer:

y=(-3/4)+2

Step-by-step explanation:

Hello there! In order to solve this problem we will have to find the slope of the line and then use the point slope formula

Firstly, lets solve for the slope by finding the change in y over the change in x:

slope (m)= [tex]\frac{y2-y1}{x2-x1}[/tex]

We will plug in the values of the points given and find that:

slope (m)= [tex]\frac{-1-2}{4-0}[/tex]

this equals (-3/4)

from here we will use the point slope formula to find for the equation that the line passes through. You can use either point for this step, I will be using A(0,2).

Point-slope equation:

[tex]y-y1=m(x-x1)[/tex]

Plugging in values:

[tex]y-2=(\frac{-3}{4})(x-0)[/tex]

after isolating y we find that the equation is:

[tex]y=\frac{-3}{4} x+2[/tex]

Hope this helps!
