Answer:
140 cm
Step-by-step explanation:
Given that:
Total length of ribbon present with Billy = 2.4 m
This ribbon is to be shared with 12 friends evenly.
Billy is doing this work of making craft for the past many years.
To find:
How many centimeters of ribbon that 7 friends will get?
Solution:
First of all, let us find out what length of ribbon will each person get.
Length of ribbon to be shared with each person = Total length of ribbon divided by total number of persons
Length of ribbon to be shared with each person = 
Now, The length of ribbon that 7 friends will get = 7
0.2 = 1.4 m
1 m = 100 cm
1.4 m = 1.4
100 cm = <em>140 cm</em>
<span>We cannot deduce about the exact location of P between J and K. But we can conclude: segment JP + segment PK = line JK.
</span><span>JP + PK = JK.
</span><span>Substitute first each.
(8z - 17) + (5z + 37) = 17z - 4
Combine like terms.
13z + 20 = 17z - 4
Isolate the variable z.
4z = 24
z = 6
The value of the variable z is then 6 units.</span>
