Answer and Step-by-step explanation:

To solve for r,

You must take all the values away from r to the other side of the equal sign. We do this using our operations: Addition, Subtraction, Multiplication, and Division.

First, we see that -3.54 isn't connected to r directly, so we can add that to both sides of the equation to get rid of -3.54 on the left side of the equation.

2.5(r - 4.4) + -3.54 + 3.54 = 6.46 + 3.54

2.5(r - 4.4) = 10

Next, we see that 2.5 is multiplying the expression (r - 4.4). We would need to divide both sides of the equation by 2.5.


(2.5(r - 4.4))/(2.5) =(10)/(2.5)

r - 4.4 = 4


Finally, we must add 4.4 from both sides to get r by itself.

r - 4.4 + 4.4 = 4 + 4.4

r = 8.4

The answer is 8.4

I hope this helps!
