Expressions with Multiplication & Division.
Evaluate each each expression for x = 3
7x ?
18/x ?
7x means to multiply: 7 times 3 = ?
18/x means to divide: 18 divided by 3 = ?
To evaluate the expressions for x = 3, we substitute x with 3 in each expression and perform the multiplication and division.
1. 7x:
Substitute x with 3:
7(3)
Perform the multiplication:
7 * 3 = 21
Therefore, 7x evaluates to 21 when x = 3.
2. 18/x:
Substitute x with 3:
18/3
Perform the division:
18 / 3 = 6
Therefore, 18/x evaluates to 6 when x = 3.
To evaluate each expression for x = 3, we simply substitute x with 3 in the given expressions and perform the necessary operations.
Expression 1: 7x
To evaluate 7x for x = 3, we substitute x with 3:
7 * 3 = 21
Therefore, for x = 3, the value of 7x is 21.
Expression 2: 18/x
To evaluate 18/x for x = 3, we substitute x with 3:
18/3 = 6
Therefore, for x = 3, the value of 18/x is 6.
