| 1) Jeevini bought 35 packages of light bulbs. She bought 69 light bulbs in all. Which equation, when solved, will tell how many light bulbs were in each package
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 light bulbs in each package. 69 = number of light bulbs
(number of packages) × (number of light bulbs in each package) = number of light bulbs 35 × A = 69 |
| 2) Aravindh collected 65 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 37 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 G to represent the number of seashells washed out to sea.
65 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 65 – G = 37

| 3) Swathi bought a box of pushpins. She put 27 pushpins on the bulletin board and had 62 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 C to represent the number of pushpins in the box.
C = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left C – 27 = 62

| 4) Kalai found 46 pretty agates near a lake. Amutha found some agates as well. When they put all of their agates together, Kalai and Amutha had 67 agates. Which equation, when solved, will show how many agates Amutha 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 Amutha found.
67 = total number of agates
(number of agates Kalai found) + (number of agates Amutha found) = total number of agates 46 + H = 67

| 5) When Selvan divided his stamp collection evenly onto 30 pages, there were 70 stamps on each page. Which equation, when solved, will tell how many stamps are in Selvan's stamp collection
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 total number of stamps.
A = total number of stamps
(total number of stamps) ÷ (number of pages) = number of stamps per page A ÷ 30 = 70

| 6) Jeevini bought 29 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: 4 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable W 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 29 × W = 64 |
| 7) Selvan collected 64 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 42 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 J to represent the number of seashells washed out to sea.
64 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 64 – J = 42

| 8) Selvanayaki bought a box of pushpins. She put 41 pushpins on the bulletin board and had 68 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 D to represent the number of pushpins in the box.
D = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left D – 41 = 68

| 9) Raj found 20 pretty agates near a lake. Keerthi found some agates as well. When they put all of their agates together, Raj and Keerthi had 61 agates. Which equation, when solved, will show how many agates Keerthi found
Answer: 3 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.
61 = total number of agates
(number of agates Raj found) + (number of agates Keerthi found) = total number of agates 20 + E = 61

| 10) When Selvan divided his stamp collection evenly onto 29 pages, there were 67 stamps on each page. Which equation, when solved, will tell how many stamps are in Selvan's stamp collection
Answer: 3 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable I to represent the total number of stamps.
I = total number of stamps
(total number of stamps) ÷ (number of pages) = number of stamps per page I ÷ 29 = 67
