**Use a Rule**

**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.

Two tiles is equal to 10 centimeters.

2 x 5 = 10 cm

Three tiles is equal to 15 centimeters.

3 x 5 = **15 cm**

Six tiles is equal to 30 centimeters.

6 x 5 = 30 cm

Eight tiles is equal to 40 centimeters.

8 x 5 = 40 cm
