Here's our equation:
Factor out the left side
(-2x - 3) - 4 = 3/4 (-8x - 12)
Simplify
-2x - 7 = 3/4 (-8x - 12)
Factor out the right side
-2x - 7 = -6x - 9
Add 7
-2x = 6x - 2
Add 6x to isolate the variable
4x = -2
Divide by 4
x = - 1/2
Here is how I simplified both sides initially. I'll only be showing the right side because this is a LOT of typing.
Begin with 3/4 (-8x - 12)
Use rule to multiply
3(-8x-12)/4
Factor 3(-8x-12)
(-8x - 12) = (-4 * 2x - 4 * 3)
Simplify (-4 * 2x - 4 * 3)
-3 * 4 (2x+3)
- 12 (2x + 3)
Now that we've factored 3/4 (-8x - 12), we're left with- 12 (2x + 3)/4.
12/4 =3, giving us -3(2x + 3)
Distribute and simplify, then you're done.

I'll have to ask you to excuse my handwriting- I had to write pretty fast.
Anyway, I hope this helps!

Answer:
B
Step-by-step explanation:
A rational number can be expressed in the form
← where a and b are integers
From the set
3 is rational as it can be expressed as
and = 3 ← rational
, and ← are irrational numbers
Thus there are 2 rational numbers out of the 5 given, thus
P( rational ) = → B
Answer:
To find the average of a set of fractions,add all fractions, then divide the sum by the number of fractions as follows: Convert the integers and mixed numbers to improper fractions.
Step-by-step explanation:
Exact Form:
b = 3/2
Decimal Form:
b = 1.5
Mixed Number Form:
b = 1 1/2
