"Simplifying a complex fraction" means Simplifying a complex fraction means to rewrite the fractions in the numerator and in the denominator with common denominators.

Step-by-step explanation:

A complex fraction is one where either  the numerator or the denominator or both contains common a fraction.

There are two methods to simplify a complex fraction-

First Method

  1. We simplify the numerator until we have one single fraction.
  2. Then we  simplify the denominator until we have one single fraction. then we divide by multiplying the numerator by the reciprocal of the denominator.
  3. The end result is simplified

Second Method

  1. Firstly we find a common denominator of all the fractions in the numerator and all the fractions in the denominator .
  2. Then we multiply the number in the numerator and denominator  of the complex fraction by a common denominator  found in step 1.
  3. The result is simplified

Given an angle, draw the opposite ray of one of its sides to form a linear pair. Find the measure of the angle formed by the ang
xz_007 [3.2K]
<span>Let opposite ray be drawn for the base side ray of the given angle. This gives angle 180° between these two rays. Angle bisectors of the given angles 50°, 90°, and 150° make respectively half of these angles : 25° , 45° and 75° with the base ray. Then measure of the angles between the bisectors of the given angles and the drawn opposite ray are 180°-25°=155°, 180°- 45° =135° and 180°- 75° = 105° respectively.</span>

where x is the one student is removed

number of 26 is left

pictures x = 26 \ 2

x = 27 \ 2 OR x = 13 pictures

x = 13.5

x = 14 pictures

Please help me i rlly need help
Mumz [18]

Answer:

3

Step-by-step explanation:

Given a line with points; (2, 5) (3, 8).

1. Find the slope of the given line

The formula for finding the slope is:

\frac{y_{2}-y_{1} }{x_{2} - x_{1}}

Substitute in the values;

x_{1} = 2\\y_{1} = 5\\x_{2} = 3\\y_{2} = 8

\frac{8-5}{3-2}

simplify;

\frac{3}{1}

= 3

2. Find the slope of the parallel line;

Remember, when two lines are parallel, they run alongside each other, of infinitely long, but they never touch. Hence two parallel lines have the same slope. Therefore, the slope of a line that is parallel to the given one will also have the same slope as the given one, which is 3.
