Describe a pattern. Then complete the table.
Question 5.
Answer:
Explanation:
From the table we know that 1 pipe section is equal to 4 meters. Multiply pipe sections with 4 then we get the meters.
Three pipe sections is equal to 12 meters.
3 x 4 = 12 meters
Four pipe sections is equal to 16 meters.
4 x 4 = 16 meters
Six pipe sections is equal to 24 meters.
6 x 4 = 24 meters
Eight pipe sections is equal to 32 meters.
8 x 4 = 32 meters
Question 6.
Answer:
Explanation:
From the table we know that 1 tile is equal to 5 centimeters. Multiply tiles with 5 then we get the centimeters.
