3(-21 + k) = 18

K=27

Step-by-step explanation:

3(-21+k)=18

-63+3k=18

3k=18+63

3k=81

K=81/3

K=27

Step-by-step explanation:

-63 + 3k =18

3k = 18 +63

K = 81/3

K = 7

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
