Step-by-step explanation:
A would be 12. If your sister is 6 years older than your brother your brother is 4
if your brother is 1/3 your age 4 times 3 you are 12
The answer is A. 3.19, all you have to do it multiply 3.19x5 then add the 2.95 hope this helps

9b+6=-30 subtract 6 from both sides
9b=-36 divide both sides by 9
b=-4
