g(x) = 0.4x - 1.8

Since the output, or g(x), is 4.6, substitute that number in for g(x).

4.6 = 0.4x - 1.8

Add 1.8 to both sides of the equation.

4.6 + 1.8 = 0.4x - 1.8 + 1.8

6.4 = 0.4x

Now, divide 6.4 by 0.4.

The answer is x = 16. The output is also x.

Travka [436]

Answer:

Using 5.25 cups of flour would make 3 batches of cookies. He made 180 cookies.

Step-by-step explanation:

To see how many batches you make all you do is take the 5.25 and divide it by 1.75 because thats how much it takes to make 1. When you divide it you get 3. If there are 5 dozen in each batch thats 60 cookies because 1 dozen is 12. Then,since he made 3 batches you multiply the 60 by 3 and you get 180.

Hope this helps!
