<h3>Answer:  4x + 42 = 5</h3>

==========================================================

Explanation:

The fractions we want to eliminate are 2/3 and 5/6. The lowest common denominator (LCD) is 6.

If we multiply both sides by the LCD, then we'll cancel out the fractions. This is because

6*(2/3) = (6/1)*(2/3) = (6*2)/(1*3) = 12/3 = 4

6*(5/6) = (6/1)*(5/6) = (6*5)/(1*6) = 30/6 = 5

So in short, the (2/3)x becomes 4x and the 5/6 becomes 5 after we multiply both sides by the LCD 6.

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

This is what the steps could look like

\frac{2}{3}x + 7 = \frac{5}{6}\\\\6*\left(\frac{2}{3}x + 7\right) = 6*\frac{5}{6}\\\\6*\left(\frac{2}{3}x\right) + 6*\left(7\right) = 6*\frac{5}{6}\\\\4x + 42 = 5\\\\

Given: Lines y and z are parallel, and ABC forms a triangle. Prove: m∠5 + m∠2 + m∠6 = 180° Lines y and z are parallel. Triangle
velikii [3]

Answer:

The correct option is;

Alternate interior angles

Step-by-step explanation:

The m∠5 + m∠2 + m∠6 = 180° proof is given as follows;

Statement                {}                        Reason

1. ABC is a triangle              {}             Given

2. y ║ z                                {}              Given

3. ∠1 ≅ ∠5; ∠3 ≅ ∠6                         Alternate interior angles

4. m∠1 = m∠5; m∠3 = m∠6        {}       Definition of (congruency) ≅

5. m∠1 + m∠2 + ∠3 = m∠LAM        {}  ∠Addition postulate

6. m∠1 + m∠2 + ∠3 = 180°        {}        Definition of straight angles

7. m∠5 + m∠2 + ∠6 = 180°        {}        Substitution property

Step 3;

Given that line y is parallel to line z, we have that the transversal AB will make equal corresponding angles with the lines y and z, therefore, ∠6 will be equivalent to segment AB extended

Which gives, ∠6 is supplementary to ∠a where ∠a = ∠1 + ∠2

Therefore, given that ∠3 is also supplementary to ∠a where as we have above, ∠a = ∠1 + ∠2, we have that ∠3 = ∠6 and ∠3 ≅ ∠6 where ∠3 and ∠6 are alternate interior angles;

Similarly, ∠1 ≅ ∠5 by alternate interior angles of two parallel lines property.
