Eight less than four times a number is less than 56. What are the possible Values of that number

Ivan

Answer:

Step-by-step explanation:

If you would like to write the following in the math expression, you can do this using these steps:

a number ... n

eight less than four times a number ... 4 * n - 8

is less than 56 ... < 56

4 * n - 8 < 56

4 * n < 56 + 8

4 * n < 64 /4

n < 64 / 4

n < 16

The possible values of that number are less than 16.

Can somebody help me with this?

Natasha_Volkova [10]

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

$x = \frac{40}{5}$

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

Therefore, X = 8° and y= 21° .

Hope it helps....
