\text{If the number is x,}\\\\~~~~~\dfrac 47 \cdot x =36\\\\\implies 4x = 36 \times 7\\\\\implies x =\dfrac{36 \times 7}4\\ \\\implies x = 9 \times 7\\\\\implies x = 63\\\\\text{Hence, the number is 63.}

Answer:

\huge\boxed{\bf\:x = 63}

Step-by-step explanation:

Given,

  • 4/7th of a number = 36

Let's take the unknown number as 'x'.

Now,

4/7 × x = 36

Take the reciprocal of 4/7 to the other side of the equation .

x = 36 × 7/4

Cancel 36 by 4.

x = 9 × 7

Multiply the 2 numbers

x = 63

forsale [732]

One of the errors made by Margie by saying the set of numbers 0, 1, -1, -21, 4, 3 is that the -21 should be the first number on the list.

The given set of numbers is:

0, 1, -1, -21, 4, 3.

Margie says that the set of numbers above is in order from least to greatest

Kindly note that:

The negative number with the highest magnitude is the lowest

The positive number with the highest magnitude is the highest

Arranging this number by carefully following the note above, the set of numbers above from the least to greatest is:

-21, -1, 0, 1, 3, 4

It is obvious that Margie made a mistake in arranging the numbers, and one of the mistake is that the -21 should be the first number on the list since it is the most negative

Sav [38]

Answer:

  1. Railway lines are example of parallel lines
  2. The floor and the walls of a room are example of perpendicular lines
  3. Two roads crossing at a signal can be termed as example of intersecting lines

Step-by-step explanation:

The lines can be related in following three ways

  1. Lines can be parallel
  2. Lines can be perpendicular
  3. Lines can be intersecting at an angle other than 90.

Now three real life examples of above three scenarios are described below:

  1. Railway lines are example of parallel lines
  2. The floor and the walls of a room are example of perpendicular lines
  3. Two roads crossing at a signal can be termed as example of intersecting lines
