What is the equation that represents the relationship between the number of trees planted (s) and the hours worked (h) if 8 trees are planted per hour?

Back

s = 8h

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 5n, 5 is the coefficient.

Front

What expression represents 'twice a number'?

Back

2b

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. In the expression 5n + 9, 9 is the constant.

Front

How do you evaluate the expression 9x + 4y when x=4 and y=8?

Back

Substituting the values: 9(4) + 4(8) = 36 + 32 = 68.

Front

If a student can plant 8 trees per hour, how many trees can they plant in 7 hours?

Back

56 trees (8 trees/hour * 7 hours = 56 trees).

Front

What is the value of the coefficient in the expression 5n + 6 - 2?

Back

5

Front

In the expression 5n + 9, what is the variable?

Back

n is the variable.

Front

What is the difference between a term and an expression in algebra?

Back

A term is a single mathematical entity (like 5n), while an expression is a combination of terms (like 5n + 9).

Front

What does it mean to evaluate an expression?

Back

To evaluate an expression means to calculate its value by substituting the variables with given numbers.
