Question

If a=3 find the value of 7a/2-6

Answer 1

Answer:

The value of $\frac{7a}{2}-6$ is $\frac{3}{2}$.

Step-by-step explanation:

The value of the expression on substituting a = 3 is:

$\frac{7a}{2}-6=\frac{7\times3}{2}-6=\frac{21}{2}-6=\frac{21-12}{6} =\frac{9}{6}=\frac{3}{2}$

Thus, the value of $\frac{7a}{2}-6$ is $\frac{3}{2}$.
