Answer:
-1/6
Step-by-step explanation:
5a+2/3=-1/6
5a=-1/6-2/3
5a=-1/6-4/6
5a=-5/6
a=(-5/6)/5
a=(-5/6)(1/5)
a=-5/30
simplify
a=-1/6
(I crossed simplify)
Next cross multiply;
3b = 1
b = 1/3
To check if the statement is true just substitute the value of b in the equation;
3b = 1
3(1/3) = 1
1 = 1
A. 0.250006, 0.250007, 0.250008
b. 0.3330001, 0.3330002, 0.3330003
(28 : 100) *6 = 1.68 (tax)
28 + 1.68 = 29.68 (total cost)
