Answer:
Step-by-step explanation:
21(5m - 3) = 63*9
105m - 63 = 567
105m = 630
m = 6
Answer:
24
Step-by-step explanation:
-27 - x = -51
+27 +27
-x = -24
x = 24
Find the length of the radius.

Find the length of the diameter.
d = 2r = 2 × 5√2 = 10√2
Point B must lie on a line AC, where C is a center of a circle.
Find equation of line AC.
A(–4, 6), C(3, 5)
The distance from B(x, y) to C(3, 5) is 5√2.

Solve system of equations.


Point B could have coordinates

But (–4, 6) are the coordinates of point A.
Therefore, point B has coordinates (10,4).
3kg+2kg=5kg
5/$3.25=0.65
price per kg=0.65
