| 3) Ponnalagu bought 30 packages of light bulbs. She bought 61 light bulbs in all. Which equation, when solved, will tell how many light bulbs were in each package
Answer: 3 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable O to represent the number of light bulbs in each package. 61 = number of light bulbs
(number of packages) × (number of light bulbs in each package) = number of light bulbs 30 × O = 61 |
| 4) Aravindh found 22 pretty agates near a lake. Chithra found some agates as well. When they put all of their agates together, Aravindh and Chithra had 70 agates. Which equation, when solved, will show how many agates Chithra found
Answer: 4 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable a to represent the number of agates Chithra found.
70 = total number of agates
(number of agates Aravindh found) + (number of agates Chithra found) = total number of agates 22 + V = 70

| 5) Kumar collected 60 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 35 seashells left. Which equation, when solved, will show how many seashells washed out to sea
Answer: 3 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable P to represent the number of seashells washed out to sea.
60 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 60 – P = 35

Answer: 3 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable J to represent the number of light bulbs in each package. 69 = number of light bulbs
(number of packages) × (number of light bulbs in each package) = number of light bulbs 37 × J = 69 |
| 9) Balaji found 33 pretty agates near a lake. Pavi found some agates as well. When they put all of their agates together, Balaji and Pavi had 63 agates. Which equation, when solved, will show how many agates Pavi found
Answer: 4 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable a to represent the number of agates Pavi found.
63 = total number of agates
(number of agates Balaji found) + (number of agates Pavi found) = total number of agates 33 + M = 63

Answer: 3 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable U to represent the number of seashells washed out to sea.
69 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 69 – U = 30
