3 answers

21,600 = 3.6c + 7.5t + 0.3m can be written as 0.3m = 21,600 - 3.6c - 7.5t
Can you explain?
Certainly!

The equation 21,600 = 3.6c + 7.5t + 0.3m represents a situation where the value of 21,600 is equal to the sum of 3.6 multiplied by the value of c, 7.5 multiplied by the value of t, and 0.3 multiplied by the value of m.

To solve for m, we want to isolate the variable m on one side of the equation.

We can start by subtracting both 3.6c and 7.5t from both sides of the equation to get rid of those terms. This gives us:

21,600 - 3.6c - 7.5t = 0.3m

Now, we still have 0.3 multiplied by m on the right side of the equation. To isolate m, we need to get rid of the coefficient 0.3. We can do this by dividing both sides of the equation by 0.3, like this:

(21,600 - 3.6c - 7.5t)/0.3 = m

Simplifying further, we get:

72,000 - 12c - 25t = m

So, the equation to solve for m is m = 72,000 - 12c - 25t.
