Step-by-step explanation:

Q1. when 3b-4a is evaluated for a=0.5 and b=-0.333333333. what is the answer?

Once

Q2. solution for equation  

Q3. which is not equivalent to

Just try all the values.

None of them makes the equation equivalent.

Q4. if a<0 and b<0 which of the following is not positive

B. a+b

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
