Question

there are 38 centipedes and millipedes in a field. each centipede has 175 pairs of legs and each millipede has 336 pairs of legs. there are 19740 legs in the field how many centipedes and millipedes are there

Answer 1

Explanation:

m = millipedes pairs of legs = 336 m

n = centipedes = 38-m pairs of legs = 175 (38-m)

summed this equals 19740 / 2 = 9870 pairs of legs

336m + 175 (38-m) = 9870

solve for m = 20 millipedes then there are 38 - m = 18 centipedes
