The expression that represents the points of Smith Elementary School scored is x - 30
Step-by-step explanation:
Let us revise some words that means operations in mathematics
- The sum ⇒ add (the sum of x and y is x + y)
- The difference ⇒ subtract (the difference between x and y is x - y)
- The product ⇒ multiply (the product of x and y is x × y)
- The quotient ⇒ divide (the quotient of x divided by y is x ÷ y)
- Less than ⇒ minus (x less than y by n is x = y - n)
- More than ⇒ plus (x is more than y by m is x = y + m)
∵ Smith Elementary School scored 30 less points in their
track meet than Jones Elementary School
- That means the score of Smith Elementary School is less than
the score of Jones Elementary School by 30
∵ Jones Elementary School scored x points
- Subtract 30 from x to find the score of Smith Elementary School
∴ Smith Elementary School scored = x - 30
The expression that represents the points of Smith Elementary School scored is x - 30
