Two lemon creams plus four fudge cookies have 450 calories. Four lemon creams plus two fudge cookies have 420 calories. How man
Gnoma [55]

Answer:

Each fudge cookie has 80 calories.

Each lemon cream has 65 calories.

Step-by-step explanation:

We will let \ell represent the calories in lemon creams and f represent the calories in fudge cookies.

Two lemon creams and four fudge cookies together have 450 calories. So, we can write the following equation:

2\ell+4f=450

And four lemon creams plus two fudge cookies together have 420 calories. So, we can write the following equation:

4\ell+2f=420

We now have a system of equations. We can solve this by elimination.

For the first equation, we can multiply both sides by -2. This way, the \ell will cancel when we add the two equations together.

So, the first equation becomes:

-4\ell-8f=-900

Add this to the second equation. Hence:

(-4\ell+4\ell)+(-8f+2f)=(-900+420)

Simplify:

-6f=-480

Divide both sides by -6. Hence:

f=80

So, there are 80 calories in one cookie.

We can use the first equation again to find the amount of calories in one cream. We have:

2\ell+4f=450

Substituting 80 for f yields:

2\ell+320=450

Then it follows that:

\ell=65

So, there are 65 calories in each lemon cream.

shepuryov [24]

Answer:

3168

Step-by-step explanation:

Here, we have s combination problem as we are selecting. The question is quite straightforward.

What the director needs to do is simply select 10 males from the total 15 males and also select 8 females from the total 11 females and add the results.

To select 10 from 15, we simply compute as 15C10 which equals 3003 ways

To select 8 from 11, we simply compute 11C8 which equals 165 ways

We simply add both to get the numbers of possible casts which is 3003 + 165 = 3168 possibilities
