| 1) Ponnalagu bought 50 packages of light bulbs. She bought 68 light bulbs in all. Which equation, when solved, will tell how many light bulbs were in each package
Answer: 2 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable X to represent the number of light bulbs in each package. 68 = number of light bulbs
(number of packages) × (number of light bulbs in each package) = number of light bulbs 50 × X = 68 |
| 2) Balaji collected 68 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 34 seashells left. Which equation, when solved, will show how many seashells washed out to sea
Answer: 2 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 seashells washed out to sea.
68 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 68 – O = 34

| 3) When Karna divided his stamp collection evenly onto 34 pages, there were 66 stamps on each page. Which equation, when solved, will tell how many stamps are in Karna's stamp collection
Answer: 2 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable A to represent the total number of stamps.
A = total number of stamps
(total number of stamps) ÷ (number of pages) = number of stamps per page A ÷ 34 = 66

| 4) Aravindh found 25 pretty agates near a lake. Pavi found some agates as well. When they put all of their agates together, Aravindh and Pavi had 70 agates. Which equation, when solved, will show how many agates Pavi found
Answer: 2 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.
70 = total number of agates
(number of agates Aravindh found) + (number of agates Pavi found) = total number of agates 25 + I = 70

| 5) Panimalar bought a box of pushpins. She put 48 pushpins on the bulletin board and had 60 left. Which equation, when solved, will tell how many pushpins were in the box
Answer: 4 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable I to represent the number of pushpins in the box.
I = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left I – 48 = 60

| 6) Tamilselvi bought 36 packages of light bulbs. She bought 66 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 F to represent the number of light bulbs in each package. 66 = number of light bulbs
(number of packages) × (number of light bulbs in each package) = number of light bulbs 36 × F = 66 |
| 7) Aravindh collected 67 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 28 seashells left. Which equation, when solved, will show how many seashells washed out to sea
Answer: 2 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable K to represent the number of seashells washed out to sea.
67 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 67 – K = 28

| 8) When Kalai divided his stamp collection evenly onto 37 pages, there were 66 stamps on each page. Which equation, when solved, will tell how many stamps are in Kalai's stamp collection
Answer: 3 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable W to represent the total number of stamps.
W = total number of stamps
(total number of stamps) ÷ (number of pages) = number of stamps per page W ÷ 37 = 66

| 9) Barathan found 35 pretty agates near a lake. Mithra found some agates as well. When they put all of their agates together, Barathan and Mithra had 70 agates. Which equation, when solved, will show how many agates Mithra 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 Mithra found.
70 = total number of agates
(number of agates Barathan found) + (number of agates Mithra found) = total number of agates 35 + V = 70

| 10) Savithri bought a box of pushpins. She put 39 pushpins on the bulletin board and had 63 left. Which equation, when solved, will tell how many pushpins were in the box
Answer: 4 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 pushpins in the box.
P = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left P – 39 = 63
