4/12 = x/18 // - x/18

4/12-(x/18) = 0

1/3-1/18*x = 0 // - 1/3

-1/18*x = -1/3 // : -1/18

x = -1/3/(-1/18)

x = 6

Choose the fraction that is greater than 3/18٫is less than 50/100٫and has 9 as its denominator
erik [133]

Answer:

4/9

Step-by-step explanation:

  • The denominator is the bottom value of a fraction, therefore we can discount 9/2
  • 1/9 = 2/18.  2/18 is smaller than 3/18 so we can discount 1/9
  • 50/100 = 0.5
    5/9 = 0.55555...
    0.55555... is greatest than 0.5, therefore we can discount 5/9
  • Answer is 4/9

Hexagon DEFGHI is translated on the coordinate plane below to create hexagon D'E'F'G'H'I':
SVETLANKA909090 [29]

Answer:

(x, y)→(x − 8, y − 7)

Step-by-step explanation:

If we take the hexagon DEFGHI coordinates and apply the rule (x, y)→(x − 8, y − 7) we get:

D (2, 5) → (2 - 8, 5 - 7) = (-6, -2) which corresponds to point D'

E (5, 5) → (5 - 8, 5 - 7) = (-3, -2) which corresponds to point E'

F (6, 3) → (6 - 8, 3 - 7) = (-2, -4) which corresponds to point F'

G (5, 1) → (5 - 8, 1 - 7) = (-3, -6) which corresponds to point G'

H (2, 1) → (2 - 8, 1 - 7) = (-6, -6) which corresponds to point H'

I (1, 3) → (1 - 8, 3 - 7) = (-7, -4) which corresponds to point I'
