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: 
Step-by-step explanation:
You have the equation 
.
Then, to solve for the variable 
from the equation you need:
Make the subtraction of the right side of the equation:
(As the denominators are 1 and 
, the least common denominator is )
Multiply to both sides:
Add 
to both sides:
And finally divide both sides by 
:
The answer would be ay-xb
11 minutes = 1 km
11 x 5 = 55 minutes
1 x 5 = 5 km.
She can walk 5 km in 55 minutes.
