Question

The number of carrots, c, is four less than twice the number of peas, p.

Which expression represents the number of carrots in terms of the number of peas?

1. p-4/2

2. 2p-4

3. p/2-4

4. 4p-2

Answer 1

The number of carrots, c, in terms of the number of peas, p, is thus calculated at 2p-4. The '-4' represents the four less, while the 2p denotes twice the number of peas.

Answer 2

Given that the number of carrots, c is 4 less than twice the number of peas, p, then:
twice the number of peas will be:
2×p=2p
four less than twice p will be:
2p-4
therefore the expression will be:
c=2p-4
the answer is 2. 2p-4.
