write and solve a word problem that can be modeled by the difference -4 - 10.
My dog lost 4 ounces this year And 10 ounces last year. What is the Difference in weight loss? Or what is total weight lost?
I am not sure I'm doing this right. The answer I got to the original question is
-4 + -10 = -14 because you change the negative to positive and positive to negative. But know there is no difference? Can you help me understand the problem?
the difference between two number m and n is m-n.
So, you are comparing -14 and -10. The difference is
-4 - (-10) = -4 + 10 = 6
That is, he lost 6 more ounces this year than last year.
yea
To solve the word problem, we have to find the difference between the two weight losses: -4 ounces this year and -10 ounces last year. In other words, we need to find the total weight lost.
To do this, we add the two weight losses together:
-4 + (-10) = -4 - 10 = -14.
So the total weight lost is -14 ounces, not zero.
The negative sign indicates that the weight loss is a decrease in weight. Therefore, your initial thought was correct, and the difference or total weight lost in this case is -14 ounces.
Sure, let's break it down step by step to understand the problem better.
The given information is that your dog lost 4 ounces this year and 10 ounces last year. We want to find the difference in weight loss or the total weight lost.
To model this problem using the difference, we need to subtract the two amounts. However, we need to be careful with the signs since weight loss is usually represented as a negative change.
So, let's first write the problem statement as a subtraction:
Total weight lost = (Weight lost this year) - (Weight lost last year)
Now let's plug in the values:
Total weight lost = (-4) - (-10)
Here, we have two negative numbers because both weight losses are negative.
To solve this, we can simplify the expression:
Total weight lost = -4 + 10
Remember that subtracting a negative number is the same as adding the opposite, so -(-10) becomes +10.
Now we can calculate the total weight lost:
Total weight lost = -4 + 10 = 6
So, the total weight lost by your dog is 6 ounces. Note that since we are dealing with a weight loss, the answer is positive in this case, not negative as in your previous calculation.
I hope this explanation helps you understand the problem better!
