Question

A wire 27 cm long is cut into two pieces. The longer piece is 3 cm longer than the shorter piece

Answer 1

The length of the shorter wire is 12 cm

Step-by-step explanation:

Let us assume that the 27 cm wire is cut into two pieces of length x cm and so the longer part would be x+3 cm.

Now we know that the total length of the wire is 27cm so

x+(x+3) = 27

2x+3 = 27

2x = 27-3

2x = 24

x = 12 cm
