Complete Question

Marla sawed a 12-meter wood plank into 8 equal pieces. Which statement best explains how Marla cut the wood plank?

a) She cut the wood into pieces that are each 1/3 meter long.

b) She cut the wood into pieces that are each 1/2 meter long.

c) She cut the wood into pieces that are each 1 meter long.

d) She cut the wood into pieces that are each 1 1/2 meter long.

d) She cut the wood into pieces that are each 1 1/2 meter long.

Step-by-step explanation:

Marla sawed a 12-meter wood plank into 8 equal pieces.

Hence,

8 equal pieces = 12 meter

1 equal pieces = x meter

Cross Multiply

8 × x = 1 × 12

x = 12/8 meters

x = 3/2 meters long

x = 1 1/2 meters long.

Therefore, Option d is the correct Option

e = 6

Step-by-step explanation:

10e - 2e - 9 = 39

8e - 9 = 39

8e = 48

e = 6

CHECK:

10(6) - 2(6) - 9 = 39

60 - 12 - 9 = 39

39 = 39
