Question

Evaluate the expression when a=

Answer 1

Answer:

$\frac{2}{15}$

Step-by-step explanation:

Substitute the values for a and c into the expression

- 2c + a

= - 2× $\frac{3}{10}$ + $\frac{11}{15}$

= - $\frac{3}{5}$ + $\frac{11}{15}$

= - $\frac{3(3)}{5(3)}$ + $\frac{11}{15}$

= - $\frac{9}{15}$ + $\frac{11}{15}$

= $\frac{2}{15}$
