Answer:
Step-by-step explanation:
We are told that the perimeter is 48 = 2L + 2W. This reduces to
24 = L + W. Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:
a) If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm
b) If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm
c) If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm
The answer to this would be C because you can multiply everything by 3 and still have a consistent-dependent system.
the answer to the first part is 2x-3
542(1+1/4)
542(4/4+1/4)
542(5/4)
677.5
7+3=4+6 Both numbers equal 10
