| 1) Chidambaram collected 68 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 36 seashells left. Which equation, when solved, will show how many seashells washed out to sea
Answer: 4 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable S 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 – S = 36

| 2) When Karna divided his stamp collection evenly onto 46 pages, there were 62 stamps on each page. Which equation, when solved, will tell how many stamps are in Karna's stamp collection
Answer: 1 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable O to represent the total number of stamps.
O = total number of stamps
(total number of stamps) ÷ (number of pages) = number of stamps per page O ÷ 46 = 62

| 3) Sriram found 38 pretty agates near a lake. Indra found some agates as well. When they put all of their agates together, Sriram and Indra had 65 agates. Which equation, when solved, will show how many agates Indra 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 Indra found.
65 = total number of agates
(number of agates Sriram found) + (number of agates Indra found) = total number of agates 38 + R = 65

| 4) Indra bought a box of pushpins. She put 50 pushpins on the bulletin board and had 66 left. Which equation, when solved, will tell how many pushpins were in the box
Answer: 1 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable B to represent the number of pushpins in the box.
B = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left B – 50 = 66

| 5) Poovazhagi bought 25 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: 2 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 light bulbs in each package. 66 = number of light bulbs
(number of packages) × (number of light bulbs in each package) = number of light bulbs 25 × U = 66 |
| 6) Aravindh collected 66 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 44 seashells left. Which equation, when solved, will show how many seashells washed out to sea
Answer: 1 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable T to represent the number of seashells washed out to sea.
66 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 66 – T = 44

| 7) When Sriram divided his stamp collection evenly onto 35 pages, there were 64 stamps on each page. Which equation, when solved, will tell how many stamps are in Sriram's stamp collection
Answer: 1 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable M to represent the total number of stamps.
M = total number of stamps
(total number of stamps) ÷ (number of pages) = number of stamps per page M ÷ 35 = 64

| 8) Murugan found 24 pretty agates near a lake. Keerthi found some agates as well. When they put all of their agates together, Murugan and Keerthi had 68 agates. Which equation, when solved, will show how many agates Keerthi found
Answer: 1 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 Keerthi found.
68 = total number of agates
(number of agates Murugan found) + (number of agates Keerthi found) = total number of agates 24 + A = 68

| 9) Nandini bought a box of pushpins. She put 43 pushpins on the bulletin board and had 65 left. Which equation, when solved, will tell how many pushpins were in the box
Answer: 2 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable Q to represent the number of pushpins in the box.
Q = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left Q – 43 = 65

| 10) Mithra bought 23 packages of light bulbs. She bought 64 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 E to represent the number of light bulbs in each package. 64 = number of light bulbs
(number of packages) × (number of light bulbs in each package) = number of light bulbs 23 × E = 64 |
