DETAILS SOWRECMATH3 10.5.006. MY NOTES ASK YOUR TEACHER Using signed numbers, write an equation that describes each of these story problems. (a) Little Bo-Peep loses 5 sheep every week from her very large flock, and they never come home! Eight weeks ago, how did the number in her flock compare with the present number? (Remember to use signed numbers.) O -5x -8 = n, (n = +40). She had 40 more sheep than at present. O -5x -8 = n, (n = -40). She had 40 fewer sheep than at present. O +5 x +8 = n, (n = -40). She had 40 fewer sheep than at present. O -5x +8 = n, (n = +40). She had 40 more sheep than at present. O +5 x -8 = n, (n = -40). She had 40 fewer sheep than at present. (b) Godzilla has been losing 30 pounds a month by watching his diet and by exercising. If he continues at this rate, how will his weight in 7 months compare with his present weight? (Remember to use signed numbers.) O +7 x -30 = n, (n = -210). He will weigh 210 pounds less than at present. O +7 x +30 = n, (n = +210). He will weigh 210 pounds more than at present. -7x -30 = n, (n = +210). He will weigh 210 pounds more than at present. +7 x +30 = n, (n = -210). He will weigh 210 pounds less than at present. O -7x -30 = n, (n = -210). He will weigh 210 pounds less than at present
