Answer:
is the expression with value of 15 when n = 7.
Step-by-step explanation:
To find the expression whose value is 15, substitute the value of n = 7 in each given expression.
Expression 1:
Substituting the value of n,
Simplifying,
Since the value of the expression is 8 which is not equal 15.
Hence expression does not have value of 15 when n = 7.
Expression 2:
Substituting the value of n,
Simplifying,
Since the value of the expression is 16 which is not equal 15.
Hence expression does not have value of 15 when n = 7.
Expression 3:
Substituting the value of n,
Simplifying,
Since the value of the expression is 14 which is not equal 15.
Hence expression does not have value of 15 when n = 7.
Expression 4:
Substituting the value of n,
Simplifying,
Since the value of the expression is 15 which is equal 15.
Hence expression has the value of 15 when n = 7.
Upon substituting n = 7 into each of the four mathematical expressions given in the question, the expression '19 - 28/n' evaluates to 15. Hence, '19 - 28/n' is the answer.
To find out which expression equals to 15 when n = 7, we substitute n = 7 into each of the given expressions and evaluate them:
Therefore, the expression '19 - 28/n' evaluates to 15 when n = 7.
