Hello from MrBillDoesMath!
Answer:
4
Discussion:
As vertical angles are equal,    Angle 3 = Angle 2,  so 
Angle 3 = 3x + 2     (A)
Angles 3 and 7 are corresponding angles and hence equal. So
Angle 3 = Angle 7   =>  use (A) above and Angle 7 =  x + 10
3x + 2 = x + 10  =>   subtract x from both sides
3x -x + 2 = x - x + 10  =>
2x + 2 = 10                 => subtract 2 from both sides
2x = 10 -2 = 8
x = 8/2 = 4
which is the first choice
Thank you,

Multiply 800 to 4/5 to see how much they make per day.
800 * 4/5 = 640
So, they make 640 fishing reels per day.
Multiply this to 30:
640 * 30 = 19,200
So they will make 19,200 fishing reels in 30 days.
This is not enough for the order.

Answer:
1/5
Discussion:
$12000 * (1/5)   = $2400
$12000 * ( 1/10) = $1200
As 2400 > 1200, (1/5) is the best way to go
Thank you,

Answer:
y=2/3x+4
Step-by-step explanation:
y-intercept is 4
rise 2
run 3
 
        
             
        
        
        
Answer:
A.
Step-by-step explanation:
The center  is at (0, -6) so the equation is:
(x - 0)^2 + ( y + 6)^2 = r^2
x^2 + (y + 6)^2 = r^2
r^2 = 11
Answer is x^2 + (y + 6)^2 = 11.
