Step-by-step explanation:
angle AOB = x+3
angle AOC = 2x + 11
angle BOC = 4x-7
angle AOC = angle AOB + angle BOC 
=> 2x +11 = (x+3) + (4x-7)
2x +11 = 5x - 4
=> 3x = 15
x = 5
subst x = 5 in the given formulas
angle AOB = x +3 =8
angle AOC = 2x + 11 = 21
angle BOC = 4x - 7 = 13

Answer:
The value of first coin will be $151.51 more than second coin in 15 years.
Step-by-step explanation:
You have just purchased two coins at a price of $670 each.
You believe that first coin's value will increase at a rate of 7.1% and second coin's value 6.5% per year. 
We have to calculate the first coin's value after 15 years by using the formula 

Where A = Future value
            P = Present value
            r = rate of interest
            n = time in years
Now we put the values 



A = (670)(2.797964)
A = 1874.635622 ≈ $1874.64
Now we will calculate the value of second coin.



A = 670 × 2.571841
A = $1723.13
The difference of the value after 15 years = 1874.64 - 1723.13 = $151.51
The value of first coin will be $151.51 more than second coin in 15 years.
 
        
             
        
        
        
On the 7th, Andi had $48 in her account. We want to find when she had $92 less than what she had on the 7th.
First, let's find out how much $92 less is:
48 - 92 = -44
We are looking for when Andi had $-44 in her account. Looking at the number line, the day Andi had $-44 in her account was on the 14th. 
The correct answer is C. The 14th.
Hope this helps!! :)
