How many 1 2/3 are in 1 1/6

Flura [38]

Answer:

7/10

Step-by-step explanation:

To find how many of x are y, you solve <em>y/x</em>.

With our numbers, we have <em>7/6 ÷ 5/3</em>.

We can turn that into <em>7/6 × 3/5</em> = <em>21/30</em> = 7/10.

What is the value of x? (Only type the numerical value. Do not type x= before your answer)

Vedmedyk [2.9K]

ANSWER

12

EXPLANATION

Two expressions for the angles in terms of x are given,

The first one is (10x-20)°

The second one is (6x+8)°

The two angles are angles on a straight line.

The sum of angles on a straight line is 180°.

This implies that,

$(10x - 20) \degree + (6x + 8) \degree = 180 \degree$

Group similar terms,

$10x + 6x= 180 + 20 - 8$

Combine like terms:

$16x=192$

$x = \frac{192}{16} = 12$

Therefore the value of x is 12
