7x + 0.9 = 10
7x = 9.1
x = 1.3 meters
7x = 9.1
x = 1.3 meters
7 x = 9.1
x = 1.3 meters
Given:
Roll of ribbon length: 10m (or 1000 cm)
Width of ribbon: 3 cm
Length of ribbon left: 90 cm
Step 1: Calculate the total length of ribbon used for the team bands.
Total length of ribbon used = Original length - Length of ribbon left
Total length of ribbon used = 1000 cm - 90 cm = 910 cm
Step 2: Count the number of team bands.
The problem states that the teacher cuts off 7 equal lengths for the team bands.
Step 3: Divide the total length of ribbon used by the number of team bands.
Length of each team band = Total length of ribbon used รท Number of team bands
Length of each team band = 910 cm รท 7 = 130 cm
Therefore, each team band is 130 cm long.
