8/9k + 9/5 = -4 - 9/7k
Mamont248 [21]

Answer:

k=-1827/685

Step-by-step explanation:

8/9k+9/5=-4-9/7k

8/9k-(-9/7k)=-4-9/5

8/9k+9/7k=-20/5-9/5

56/63k+81/63k=-29/5

137/63k=-29/5

k=(-29/5)/(137/63)

k=(-29/5)(63/137)

k=-1827/685

Please help due in 20 minutes!!
Nikitich [7]

Answer:

length is 15.5 and the width is 12.5

Step-by-step explanation:

Length rectangle = 3cm. longer than its width.

Rectangle perimeter = 56 cm.

find its dimensions?

P = 2L +2w

L= w + 3

P= 56

P = 2L +2w

56 = 2(w+3) +2(w)

56 = 2w +6 + 2w

4w= 56 - 6

4w = 50

w = 50/4

w = 12.5

L= 12.5 +3 = 15.5

L= 15.5

Solution:

Length= 15.5 cm

Width = 12.5 cm

i know it looks complex but i hope this helps :)
