Answer:
C
Step-by-step explanation:
circumfrence= 2πr
56.52=2πr
divide both sides by 2π to get your answer
r=9
C
The coordinates of the point that is one-half the distance between A(-1,-2) and B(6,12) is (2.5,5)
What is the midpoint?
The mid-point lies midway between the two ends. Its x value lies in the middle of the other two x values. Its y value lies in the middle of the other two y values.
Given, 

Let M is a midpoint of AB, then

The midpoint of point AB is M(2.5,5)
Therefore, the coordinates of the point which is one-half the distance between A(-1,-2) and B(6,12) is M(2.5,5).

Answer:
1. X = 1 - 3y
2. -5/6x + 7/3
Those are the answers to the problems
Answer:
Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8
-144+108y/4 - 10y = -8
-144 + 108y - 40y/4 = -8
-144 + 108y - 40y = -32
108y - 40y = -32+144
68y = 112
Y= 1.64
2-4x+9y=14
12x-10y= -8
2-14+9y = 4x
-12 + 9y = 4x ( equation 3)
(Put in equation 2)
Take it like this
27% of x = 162
27/100 * x = 162
x = 162*100/27
x=600
Therefore, 27% of 600 is 162
