Describe the relationship between n and 4 that will make the value of the expression 7xn4greater than7

valina [46]

Answer:

As per the statement: the value of the expression 7 x n/4 greater than 7.

To describe the relationship between n and 4.

"greater than" symbol is represented by '>'

The value of expression $7 \times \frac{n}{4}$ grater than 7 is;

$7(\frac{n}{4}) > 7$

Divide by 7 both sides we get;

$\frac{n}{4} > 1$

Multiply both sides of an equation by 4 we get;

$n > 4$

Therefore, the relationship between n and 4 is, $n > 4$
