| 1) Moorthi collected 66 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 47 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 Q 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 – Q = 47

| 2) Parveen bought a box of pushpins. She put 32 pushpins on the bulletin board and had 65 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 H to represent the number of pushpins in the box.
H = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left H – 32 = 65

| 3) When Raj divided his stamp collection evenly onto 45 pages, there were 64 stamps on each page. Which equation, when solved, will tell how many stamps are in Raj's stamp collection
Answer: 3 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve: You can use the variable L to represent the total number of stamps.
L = total number of stamps
(total number of stamps) ÷ (number of pages) = number of stamps per page L ÷ 45 = 64

| 4) Balaji found 22 pretty agates near a lake. Pavi found some agates as well. When they put all of their agates together, Balaji and Pavi had 67 agates. Which equation, when solved, will show how many agates Pavi 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 Pavi found.
67 = total number of agates
(number of agates Balaji found) + (number of agates Pavi found) = total number of agates 22 + F = 67

| 5) Indra bought 27 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 M 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 27 × M = 66 |
| 6) Anand collected 64 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 30 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 I 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 – I = 30

| 7) Nandini bought a box of pushpins. She put 42 pushpins on the bulletin board and had 68 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 O to represent the number of pushpins in the box.
O = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left O – 42 = 68
