Answer:
x= 6
Step-by-step explanation:

You will subtract 10x from 12x and get 2x

Subtract 4 from 16 to get 12

You will then divide both sides by 2
 =
 = 
x= 6
The second one is hard to read but since ∠3 is 54° you should just start from there
Hope this helps

Answer:
129.3 in²
Step-by-step explanation:
The shaded segment is calculated as
area of sector ABC - area of triangle ABC
area of sector = area of circle × fraction of circle
A = πr² × 
    = π × 18² × 
    = 324π ×  = 54π in²
 = 54π in²
area of Δ ABC =  × 18 × 18 × sin60°  ≈ 40.30 in²
 × 18 × 18 × sin60°  ≈ 40.30 in²
Then
shaded area = 54π - 40.30 ≈ 129.3 in² ( to the nearest tenth )
 
        
             
        
        
        
Answer:
I am pretty sure the answer would be $107.31. Sorry if I'm wrong. 
Step-by-step explanation:
First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy. 
45.99 / 3 = 15.33
15.33 x 7 = 107.31
