Charlie’s weight is 5 times as great as the weight of his little sister, Tali. If the total weight of the two children is 132 pounds, how much does each Child weigh?
To find the weight of the ostrich, we can use algebraic equations. Let's assume the weight of Mark's pet dog is "x" pounds. According to the problem statement, the ostrich weighs 3 times as much as Mark's dog, so the weight of the ostrich is 3x pounds.
Now, we know that the combined weight of the ostrich and the dog is 448 pounds. So we can add the weights of the ostrich and the dog and set it equal to 448 pounds:
3x + x = 448
Simplifying the equation, we have:
4x = 448
To find the weight of the ostrich, we need to solve for x. We can do this by dividing both sides of the equation by 4:
x = 448 / 4
x = 112
So, the weight of Mark's pet dog is 112 pounds. To find the weight of the ostrich, we can substitute this value back into the equation for the ostrich's weight:
3x = 3 * 112 = 336
Therefore, the ostrich weighs 336 pounds.
