X = total people
3/8x are children......that leaves 5/8 remaining...
3/4 of remaining are men...3/4(5/8) = 15/32x are men
1/4 of remaining are women....1/4(5/8) = 5/32x are women
140 more women then children...so children - 140 = women
3/8x - 140 = 5/32x
3/8x - 5/32x = 140
12/32x - 5/32x = 140
7/32x = 140
x = 140 * 32/7
x = 4480/7
x = 640
total people is 640 <===
children : 3/8(640) = 240
men : 15/32(640) = 300
women : 5/32(640) = 100
Answer:
1st piece = 4 ft
2nd piece = 4 ft
3rd piece = 8 ft
Step-by-step explanation:
Let 3rd piece's length be "x"
Each of the two remaining pieces will be 4 feet shorter, so each other piece would be:
x - 4
and
x - 4
Since sum of all 3 pieces is 16, we can write:
1st piece + 2nd piece + 3rd piece = 16
x - 4 + x - 4 + x = 16
3x - 8 = 16
3x = 24
x = 24/3
x = 8
Third piece is 8 feet and each remaining piece is 8 - 4 = 4 feet and 4 feet
1st piece = 4 ft
2nd piece = 4 ft
3rd piece = 8 ft
.5 because 100/2 is 50 and there’s 1.00 and when you divide that it’s .5
