Question

Plz help its 7th grade distributive proprty

Answer 1

[(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

Answer 2

a = 3.9

Explanation:

Isolate the varible by dividing each side by factors that don't contain the variable.
