Answer: 7 1/30

Step-by-step explanation:

Tina loves to read. Before breakfast, she read 2 1/2 pages, at lunch she read 3 1/5 pages, and after dinner she read 1 1/3 pages. To find the total, we add all the pages together. This will be:

2 1/2 + 3 1/5 + 1 1/3

The LCM of 2, 5 and 3 is 30.

= 2 15/30 + 3 6/30 + 1 10/30

= 6 31/30

= 7 1/30.

The interior angles formed by the sides of a quadrilateral have measures that sun to 360° What is the value of X?

densk [106]

Answer:

x = 34

Step-by-step explanation:

Sum the 4 interior angles and equate to 360, that is

3x - 6 + 2x + 108 + 88 = 360 ← simplify left side

5x + 190 = 360 ( subtract 190 from both sides )

5x = 170 ( divide both sides by 5 )

x = 34
