Answer:

x=12

Step-by-step explanation:

The three angles add to a straight line which is 180 degrees

20 + 6x-2 + 90 = 180

Combine like terms

108 + 6x = 180

Subtract 108 from each side

108+6x-108 = 180-108

6x =72

Divide each side by 6

6x/6 = 72/6

x=12

An archaeologist is categorizing the artifacts he has discovered. Two-thirds of the artifacts are shards of pottery. One-eighth
Reika [66]

Answer:

Personal items=15

Step-by-step explanation:

We are given:

Total number of artifacts = 72.

We are told that 2/3 of total artifacts are shards of pottery.

\text{Shards of pottery}=72*\frac{2}{3} =24*2=48

We are also told that 1/8 of total artifacts are tools.

\text{Tools}=72*\frac{1}{8}=9

Now we will find out number of personal items by subtracting combined number of shards of pottery and tools from total number of artifacts.

\text{ Personal items}=72-(48+9)

\text{ Personal items}=72-57=15

Therefore, there are 15 personal items.
