An equation is a math sentence. Which letter(s) represent only an expression, not a complete math sentence? (Could be more than one answer.)
1. 3y=14
2. x-6
3. a/7=6
4. 3 + 5b
5. 12=0.8(5) + c
6. 6/p + 0.5-2/3(p)

Answer:

[tex]Pr = 6.67\%[/tex]

Step-by-step explanation:

Given

[tex]n = 10[/tex] i.e. 10 people

Required

Probability of being next to each other

First, we calculate the total possible arrangements (without any restriction)

[tex]Total = n![/tex]

[tex]Total = 10![/tex]

If the three are to be next to each other,

First, we arrange the three

[tex]r_1 = 3![/tex]

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)

The arrangement is:

[tex]r_2 =8![/tex]

So, the total arrangement, when they have to be next to one another is:

[tex]r = r_1 * r_2[/tex]

[tex]r = 3! * 8![/tex]

The probability is:

[tex]Pr = \frac{r}{n}[/tex]

[tex]Pr = \frac{3! * 8!}{10!}[/tex]

Expand

[tex]Pr = \frac{3*2*1 * 8!}{10*9*8!}[/tex]

[tex]Pr = \frac{3*2*1}{10*9}[/tex]

[tex]Pr = \frac{6}{90}[/tex]

[tex]Pr = 0.0667[/tex]

Express as percentage

[tex]Pr = 0.0667 * 100\%[/tex]

[tex]Pr = 6.67\%[/tex]

Answer:

3

Step-by-step explanation:

Prime factorize 42 and 3 and you'll eventually get 3 as your answer.

Answer:

3

Step-by-step explanation:

Since you are looking for the greatest common factor, 3 cant have many factors other than itself. So it would be 3, when simplified its similar to 42/3 and 3/3 where it would be 14 and 1.

Sorry, I don't think there's enough information to solve the problem.

Step-by-step explanation:

Well, there's no numbers to say what the measures of the vertices are. Also, it seems like the question got cut out because the second sentence is incomplete.

Answer:

domain is all real numbers except -6

Step-by-step explanation:

Answer:

domain is all real numbers except -6

Step-by-step explanation:

A value of x of 4 guarantees that the angles 2 · x + 19 and x + 23 could be alternate exterior angles highlighted between two parallel lines.

If two angles are alternate exterior, then both angles have the same measure. Thus, we have the following expression:

2 · x + 19 = x + 23     (1)

Now we proceed to solve for x:

x = 4

A value of x of 4 guarantees that the angles 2 · x + 19 and x + 23 could be alternate exterior angles highlighted between two parallel lines.

Answer:

Option D, I agree with neither Elena nor Lin

Step-by-step explanation:

The remaining part of the question is attached herewith

Solution

As we can see in the image  

ED is perpendicular to AB and BC is perpendicular to AB

Thus, as per the Pythagoras theorem,  

AC^2 = AB^2 + BC^2  

14^2 = 6^2 + BC^2

BC^2 = 196-36 = 160

BC = 12.649 OR 12.65

Hence, option D

I agree with neither Elena nor Lin

Answer:

14

Step-by-step explanation:

x / y = 5 / 3, then 3x = 5y , x = 5/3y

we can type 5/3y instead of x ;

5/3y + y = 8/3y = 56, then y = 21

.

now let's find x ;

x - 21 = 56, then x = 35

x - y = 35 - 21 = 14

Answer:

Q'(1, -5)

R'(1, 1)

S'(5, -5)

Step-by-step explanation:

Since you're reflecting deflecting across x equals to 1 ,also our Q and R Coordinates are on the line x equals to 1 so it's going to stay same only the S coordinates would change. the X value for the coordinates gonna be +ve and Y value gonna be -ve. Because after the reflection of the point the point would lie in the fourth quadrant and in the Forth quadrant Xvalue is positive and Y value is negative.
