Answer:
The baby weighs 30 pounds.
Siva
explains
The
baby and the man
weigh 162 pounds more than the canine and not baby and man weigh 162
lbs, their weight becomes 162+9 = 171 lbs.
The dog only weighs 9 lbs and if we add 162 the combined weight of baby
and man becomes 171 lbs.
Ai answer
Let's denote the weights of the man, the baby, and the dog as M, B, and D, respectively.
The given information can be translated into equations:
1. M + B + D = 180 (The total weight of the man, baby, and dog is 180 pounds.)
2. B + M = D + 162 (The baby and the man weigh 162 pounds more than the dog.)
3. D = 0.7B (The dog weighs 70% less than the baby.)
Now, let's solve these equations to find the weight of the baby (B):
Substitute equation (3) into equation (2):
B + M = 0.7B + 162
Combine like terms:
0.3B + M = 162
Substitute equation (1) into the above equation:
0.3B + (180 - B - D) = 162
Substitute equation (3) into the above equation:
0.3B + (180 - B - 0.7B) = 162
Combine like terms:
0.3B + (180 - 1.7B) = 162
Combine like terms again:
-1.4B + 180 = 162
Subtract 180 from both sides:
-1.4B = -18
Divide by -1.4 to solve for B:
B = 12.8571
So, the baby weighs approximately 12.8571 pounds.
