Which expression has a value of 15 when n = 7? 1: 43 minus 5 n
2: 3 n minus 5
3: 6 n minus 28
4: 19 minus StartFraction 28 Over n EndFraction

is the expression with the 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:

Substitute the value of n & simplify,

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 & simplify,

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 & simplify,

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 & simplify,

Since the value of the expression is 15 which is equal 15.

Hence expression has the value of 15 when n = 7.

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
