Answer:
[tex]\frac{2}{15}[/tex]
Step-by-step explanation:
Substitute the values for a and c into the expression
- 2c + a
= - 2× [tex]\frac{3}{10}[/tex] + [tex]\frac{11}{15}[/tex]
= - [tex]\frac{3}{5}[/tex] + [tex]\frac{11}{15}[/tex]
= - [tex]\frac{3(3)}{5(3)}[/tex] + [tex]\frac{11}{15}[/tex]
= - [tex]\frac{9}{15}[/tex] + [tex]\frac{11}{15}[/tex]
= [tex]\frac{2}{15}[/tex]
