What is the expression and value of "six less than the quotient of a number and two, increased by ten"when n=20 7 (n)/(2)-6+10 when n=20 the value is 14. 6-(n)/(2)+10 n=20 the value is 6. (n)/(2)-6+10 when n=20 the value is 17. 6-(n)/(2)+10 when n=20 the value is 3.

To solve this problem, we need to translate the given expression into a mathematical expression and then evaluate it when $n=20$.<br /><br />The expression "six less than the quotient of a number and two, increased by ten" can be written as:<br /><br />$\frac{n}{2} - 6 + 10$<br /><br />Now, let's substitute $n=20$ into the expression:<br /><br />$\frac{20}{2} - 6 + 10$<br /><br />Simplifying the expression:<br /><br />$10 - 6 + 10$<br /><br />$= 14$<br /><br />Therefore, the value of the expression $\frac{n}{2} - 6 + 10$ when $n=20$ is 14.
