Answer 2

To find the solution to the equation (6, 3a+2, 9a) ÷ 12 = 2.76, we need to solve for the value of 'a'.

Let's break down the equation step by step:

Step 1: Simplify the expression on the left side of the equation. (6, 3a+2, 9a) ÷ 12 can be simplified as follows: (6 + 3a + 2 + 9a) ÷ 12 (8 + 12a) ÷ 12

Step 2: Set the simplified expression equal to 2.76 and solve for 'a'. (8 + 12a) ÷ 12 = 2.76

To isolate 'a', we will first get rid of the constant term by subtracting 8 from both sides: (8 + 12a) ÷ 12 - 8 = 2.76 - 8

Simplify the left side: (12a) ÷ 12 = -5.24

Now, divide both sides by 12 to solve for 'a': a = -5.24 ÷ 12 a ≈ -0.43666666667 (rounded to several decimal places)

So, the solution to the equation is approximately a = -0.44.
