K+20=t solve for the letter k

t-20

Step-by-step explanation:

k+20=t

Subtract 20 from both sides:

k= t-20

K=t-20

Step-by-step explanation:

20=K

We move all terms to the left:

20-(K)=0

We add all the numbers together, and all the variables

1K+20=0

We move all terms containing K to the left, all other terms to the right

K=-20

K=-20/-1

K=t-20

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

the answer is 13 cm
