[tex]\text {\underline {The First Step is to do Keep Change Change (KCC)}}[/tex]

[tex]\text {Keep: 4.25}\\\text {Change: - into +}\\\text {Change: 2.5x into -2.5x}[/tex]

[tex]\text {\underline {The Next Step is to Flip the Equation}}[/tex]

Hey there!☺

[tex]Answer:\boxed{x=-4.2}[/tex]

[tex]Explanation:[/tex]

[tex]4.25-2.5x=14.75[/tex]

Let's start by simplifying both sides in the equation.

[tex]4.25+-2.5x=14.75\\-2.5x+4.25=14.75[/tex]

Now we subtract 4.25 from both sides in the equation.

[tex]-2.5x+4.25-4.25=14.75-4.25\\-2.5x=10.5[/tex]

Now in our third/final step, we will divide both sides by -2.5.

[tex]\frac{-2.5x}{-2.5}= \frac{10.5}{-2.5}[/tex]

Now we simplify 10.5/-2.5.

[tex]\frac{10.5}{-2.5}=-4.2[/tex]

[tex]x=-4.2[/tex]

You ask a friend to think of a number from 7 to 14. What is the probability that his number will be an even number? Answer as a fraction in simplest form.

Answers

Answer:

1/2

Step-by-step explanation:

Not sure but

I am assuming we have 8 integers :

All or (A) = {7,8,9,10,11,12,13,14} = n(A) = 8

Hence, the probability of any one outcome is 1/8.

Therefore, as you can detect, there are 4 numbers that are even numbers which means :

Even or (E) = {8, 10, 12, 14} = n(E) = 4

So, let E imply this occurrence

E x A

= 4 x 1/8

= 4/8

= 1/2

Probability of getting an even number from7 to 14 is equals to ( 1/ 2).

What is probability?

" Probability is defined as the mathematical calculation to represents the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

[tex]Probability = \frac{Number of favourable outcome }{Total number of outcomes}[/tex]

According to the question,

Given,

  Total number from 7 to 14 = { 7, 8, 9, 10, 11, 12, 13, 14}

Total number of outcomes = 8

Possible outcomes of even number ={ 8, 10, 12, 14}

Number of favourable outcomes = 4

Substitute the value in the formula we get,

Probability = ( 4 / 8)

                  = ( 1 / 2) ( fraction in simplest form)

Hence, probability of getting an even number from7 to 14 is equals to ( 1/ 2).

If M is the midpoint of segment AB, then which of the following statements is/are true? AB=MB AM=MB Segment AM is congruent to segment MB.

Answers

AB is the large segment.

AM is half of the large segment.

MB is the second half of the large segment.

-Segment AM is congruent to segment MB.

- AM = MB.

What is a midpoint of a line segment?

The midpoint of a line segment is given as,

x = (a + c)/2

y = (b + d) / 2

Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.

We have,

If M is the midpoint of segment AB, then the following statements are true.

- AB = 2MB

Since M is the midpoint of AB, MB is half the length of AB.

Therefore,

AB is twice as long as MB.

- AM = MB

Since M is the midpoint of AB, AM, and MB are equal in length.

This is a property of the midpoint of a segment.

Now,

Segment AM is congruent to segment MB.

Since AM and MB are equal in length (as stated in statement 2), they are congruent to each other.

Therefore,

Segment AM is congruent to segment MB with AM = MB statement being true.
