Answer:
Therefore, when you know x, just substitute x into the equation, we can find out w.
w = x + 2,439
Explanation:
Allow me to revise your question:
The total weight of a truck and its load is w pounds. Let x be the weight of the load . When it's empty the truck weighs 2,439 pounds. In this equation tells how to find w when you know x?
My answer:
Given:
- w is the total weight of a truck and its load
- Let x is the weight of the load
We know that when it's empty the truck weighs 2,439 pounds, it means the weight of a truck is 2,439 pounds.
So we can form the equation:
w = x + 2,439
Therefore, when you know x, just substitute x into the above equation, we can find out w.
For example, we know x = 2,000 pounds, so the total weight (w) is:
w = 2,000 + 2,439 = 4,439 pounds.
Hope it will find you well
