Products. 6661422 Then +14 is the greater number, Then 200+ is the prize of B, And x 200+ 200+x, per question. Whence Or, 2x 1200, 400, by transposition, etc. Therefore r = 600, And 200 + 3x 400; Also, 200400+ 600 1200. (12.) Let x be the number. Then 12+ 3x :: 2 : 9, per question, And 9x 24+6x, by multiplying the extremes and means, Whence 3x=24, And x 8. And 336(x+14)-9x=6x+84 - 9x, per question. (13.) Let x be the units of time, after passing the fort, in Whence 3x51, by transposition, etc. Therefore = 17; And x+14= 31. (3.) Let x be the number required. Then (+20) - 1210, per question, Or, 2x+40 3630, by clearing of fractions, etc. Therefore x = 13. (4.) Let x be the sum each laid out. Then x120 A.'s money; And x- 80 B.'s money. = Also, 3(x80)=x+120, per question. Or, 3x 240=x+120; Whence 2x 360, by transposition, etc. (5.) Let x be the number required. which the ship overtakes the boat. Then 5 is the miles sailed by the ship, And 3x+13, the miles sailed by the boat. When 5x=3x+13, per question, Therefore x = 480. (15.) Let 9x and 7x be the parts. Then 9x+7x= 2000, per question. And x 125. Therefore 9x=1125; (16.) Let x be the sum. (17.) Let x be the number of hours travelled. Then 10x is the distance travelled by A. And 8x the distance travelled by B. Also, 10x200; And 8x160. (18.) Let x be the man's age. Or, 5x = 240; Therefore x = 48. (19.) Let x be the number. Then xx96, per question, 4x1920, by clearing of fractions, Therefore x = 1920. (20.) Let x be the length of the post. Whence 35x=7x+ 15x + 455, (21.) Let x be the number. Then(x+10) 66, per question, Whence 3x+30= 330, by clearing of fractions. Therefore = 100. The answer is misprinted 91, instead of 100. |
