Write a 2 column proof Prove x=45

Mathematics

Answer:

Proved that x= 45

Step-by-step explanation:

From the diagram we can see that 2x+6  and 96 are vertical opposite angles

Vertical opposite angles are the pair of angles that are same.

2x+6 and 96 are vertical opposite angles

so they are equal

2x+6 = 96

Now we solve for x, subtract 6 from both sides

2x+6-6= 96-6

2x= 90

divide by 2 on both sides

x= 45

2 column proof

2x+6 and 96                        Vertical opposite angles

2x+6 = 96

x=45                                    vertical opposite angles are congruent

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

<u>Vertical Angles</u> are the pair of congruent angles opposite each other when two lines cross

In the given figure

(2x+6)\°=96\° -----> by vertical angles

solve for x

2x=96\°-6\°

2x=90\°

x=45\° ------> is ok

The neither of the statement is not from the least to greatest.

According to the statement

We have to find that the order of the numbers from least to the greatest.

So, For this purpose, we know that the

The order of an element in a group is the smallest positive power of the element which gives you the identity element.

From the given information:

We have to find the statement which represent the numbers in order from least to greatest.

And we know that the square root of 8 is 2.82.

then

A) 2.31, 2, √8

2.31, 2, 2.82

this is not from least to greatest.

Then

B) √8, 2, 2.31

2.82, 2, 2.31

This is from greatest to least.

C) 2,√8, 2.31

2,2.82, 2.31

This is not from least to greatest

D) √8, 2, 2.31

2.82, 2, 2.31

This is not from least to greatest

So, The neither of the statement is not from the least to greatest.

6-7(x+1)= -3(2-x)<br> How do you solve this?
kicyunya [14]
<h3><u>Explanation</u></h3>
  • Given the equation.

6 - 7(x + 1) =  - 3(2 - x)

  • Distribute/Simplify

6 - 7x - 7 =  - 6 + 3x \\  - 1 - 7x =  - 6 + 3x

  • Solve the equation for x-term by making x as the subject.

- 1 + 6 = 7x + 3x \\ 5 = 10x \\  \frac{5}{10}  = x \\  \frac{1}{2}  = x

  • Answer Check by substituting the value of x in the equation.

6 - 7( \frac{1}{2} ) - 7 =  - 6 + 3( \frac{1}{2} ) \\ 6 -  \frac{7}{2}  - 7 =  - 6 +  \frac{3}{2}  \Longrightarrow \sf{You \:  \: can \:  \: change \:  \: sides \:   \: to \:  \: make \:  \: it \:  \: easier} \\ 6 - 7 + 6 =  \frac{7}{2}  +  \frac{3}{2}  \\ 5 =  \frac{10}{2}  \\ 5 = 5 \:  \green{ \checkmark}

The equation is true for x = 1/2.

<h3><u>Answer</u></h3>

<u>\large \boxed{x =  \frac{1}{2} }  \:  \:  \:  \: \green{ \checkmark}</u>
