Algebra Write an equation with a letter for the unknown. Then solve.
1. What is the mass of 2 boxes of raisins?
2. The scissors have a mass of 90 grams. What is the mass of the stapler?
Homework Helper
Three small packets of peanuts have a total mass of 30 grams. Each packet has the same mass. What is the mass of 1 packet of peanuts?
W rite an equation with a letter for the unknown.
30 ÷ 3 = m
So, 1 packet of peanuts has a mass of 10 grams.
Lesson 4
Solve Mass Problems
Divide to find the answer.
30 ÷ 3 = 10m = 10 grams
42 g
540 g
42 + 42 = x; 84 g
