Answer:

Step-by-step explanation:

This weird notation just means we are going to put one equation inside the other, and then solve.

Makes more sense when you write it like this:

g ( f ( x ) )

To solve, we are going to take the 3, plug it into the f ( x )

g ( f ( 3 ) )

^ This makes it a lot easier to understand what we have to do.

----------------------------------------------------------------------------------------------------------

Ok, so now we evaluate f ( x ) at 3.

4 ( 3 ) - 2

f( x ) = 10

Then we plug it into g ( x )

4 ( 10 ) - 1

= 39

Here's how it looks in total:

4 ( 4 ( 3 ) - 2 ) - 1 = 39

Slightly more complicated, but that's why i broke it down step by step.

Answer: It will take 10 minutes.

Explanation:

Cone A: 2.5mL x 10 minutes = 25 mL of ice cream falls in 10 minutes. 30mL-25mL=5mL

Cone B: 1.5mL x 10 minutes = 15 mL of ice cream falls in 10 minutes. 20mL-15mL=5mL

in 10 minutes, they’ll both be at 5mL

Answer:

The number of 43 cent stamps Esmeralda bought is 19.

Step-by-step explanation:

Given:

Esmeralda bought 12.22 worth of 43 cent stamps and 81 cent stamps. The number of 81 cent stamps was 14 less than the number of 43 cent stamps.

Now, to solve the equation 0.43 s + 0.81 ( s − 14 ) = 12.22 for s and to find the number of 43 cent stamps.

Let the number of 43 cent stamps be $s.$
