Jane has three boxes she needs to ship. Box X weighs kg more than Box Y and Box Z weighs kg more than Box Y. She measured the total weight of all the boxes and it was found to be kg. Which equation can be used to find the weight, w of Box Y?
A=3w-15 1/4=55 1/4
B=w-24 1/2=50 3/4
C= 3w + 15 3/4 = 55 3/4 (my answer)
D=w+22 1/2 = 48 3/4
You forgot the weight of the boxes.
sorry 3 1/2 for box x box y and 7 are 12 1/4 kg more than box y and total weight is 55 3/4
it’s A
To find the weight of Box Y, let's go step by step:
1. Let's assume the weight of Box Y is "w" kg.
2. It is given that Box X weighs kg more than Box Y. So the weight of Box X is (w + kg).
3. Similarly, it is given that Box Z weighs kg more than Box Y. So the weight of Box Z is (w + kg).
4. The total weight of all three boxes is kg. So the equation can be written as: w + (w + kg) + (w + kg) = kg.
Simplifying the equation:
3w + 2kg = kg
Now, let's look at the given answer choices:
A) 3w - 15 1/4 = 55 1/4
B) w - 24 1/2 = 50 3/4
C) 3w + 15 3/4 = 55 3/4
D) w + 22 1/2 = 48 3/4
Looking at the equation we derived (3w + 2kg = kg), we can see that the correct answer should have a similar form.
Option C) 3w + 15 3/4 = 55 3/4 fits the form of our equation, so it is the correct answer.
Therefore, the equation that can be used to find the weight of Box Y is C) 3w + 15 3/4 = 55 3/4.
