Question 1092937: There are 103 major sources of pollen in the US. These pollen sources are catagorized as grasses, weeds, and trees. If the number of weeds is 5 less than twice the number of grasses, and the number of trees is 3 more than twice the number of grasses, find the number of grasses, weeds, and trees that are major pollen sources. Answer by ikleyn(52781) (Show Source):
G = # of grasses
W = # of weeds
T = # of trees.
W = 2G -5 <<<---=== From the condition
T = 2G + 3 <<<---=== From the condition
G + W + T = 103
G + (2G-5) + (2G+3) = 103 ====================>
5G - 2 = 103,
5G = 103 + 2 = 105 ====> G = = 21.
From this point, can you complete the solution on your own ?
