6. The population of the Chippewa tribe is one third the population of the Seminole tribe. The population of the Chippewa tribe is 189,000. What is the population of the Seminole tribe?

Answer 1

6 1/2 + 4 3/4 = 26/4 + 19/4 = 45/4 = 11 1/4

or 6.5+ 4.75 = 11.25

25 -11.25 = 13.75 pounds to go

25 - 11 1/4 = 13 3/4 pounds to gain in the last two weeks

3 1/8 - 1 3/10 = 25/8 -13/10 = 125/40 - 52/40 = 73/40 = 1 33/40 acres left

-2x/3 = 6

x = 6(-3/2) = -9

48 = 3P/4

P =(4/3)48 = 64 quarts of punch

8/3 x 850 = 8(283 1/3) = $2266.67= her monthly income

189,000 x 3 = 567,000 population for the 2nd tribe
