Answer:
[(2/3)(9a)] + [(2/3)(6)] = 27.4
a = 3.9
Explanation:
Let's start with the first portion of the equation: (2/3) * (9a)
Rewrite (2/3) * (9a) as => (2/3) * (9a/1); multiplying the numerator with the numerator, as well as the denominator with denominator, you should get (18/3a) => 6a
Onto the second part of the equation.... quite simple: (2/3)(6) = 12/3 = 4
Putting it all together, the entire equation is equal to 27.4
Finding the value of a: the new equation is 6a + 4 = 27.4
Subtract 4 from the total value of 27.4, and you should get 23.4
After this, your equation should be 6a = 23.4
Now, to finally find the value of (a), divide 23.4 by 6
This should leave you with a = 3.9
