Зm — 2n = 12
can someone help me on khan

Step-by-step explanation:

solving for m

3m-2n=12

+2n        +2n

3m=2n+12 (divide 3 by all numbers)

solving for n

3m-2n=12

-3m       -3m

-2n=-3m+12 (divide all numbers by -2)

answer: 193

explanation:

200-7 = 193

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
