The mass of a jar of beans is 525 g. If the jar has a mass of 25 g, the beans alone must have a mass of:
beans+25 = 525
so, beans = ?
500
To find the mass of the beans alone, you can subtract the mass of the jar from the total mass of the jar and beans.
Let's label the mass of the beans as "m" (in grams), and the mass of the jar as "j" (in grams). We are given that the total mass of the jar of beans is 525 g, and the mass of the jar is 25 g.
So, we have the equation: m + j = 525
Substituting the values we know, we can rewrite the equation as: m + 25 = 525
To solve for "m", we need to isolate it on one side of the equation. We can do this by subtracting 25 from both sides of the equation:
m + 25 - 25 = 525 - 25
This simplifies to: m = 500
Therefore, the beans alone must have a mass of 500 g.
