Answer:
a = 6
Step-by-step explanation:
Hello!
Solve:
- 4(3a - 4) = 56
- 3a - 4 = 14 (factoring out 4)
- 3a = 18 (adding 4 to both sides)
- a = 6 (dividing by 3)
Another way:
- 4(3a - 4) = 56
- 12a - 16 = 56 (distributive property)
- 12a = 72 (moving like terms)
- a = 6 (dividing by 12)
Distributive Property of Multiplication:
The process of distributing the outside factor to the terms in the parenthesis.
Example:

Answer: $38.66
You find the amount that is taxed by multiplying 0.08 by $35.80 which is $2.86 and adding that to the original amount.
1% is 1.68, so 3/4% will be 1.26.
_____
3/4 of 8 is 6, so 3/4 of 16 is 12. It's all a matter of decimal point management.
