Answer:

B, C

Explanation:

So basically what this question is asking is "how much food is she giving to both the animals combined per day?"

It says she feeds them both a certain amount of grams a day, but doesn't tell us how many grams, so we'll use the variables k and d.

k will represent the amount of food that Ariane feeds her kitten,

and d will represent the amount of food she gives to the dog.

Keep in mind that it never attaches any numbers to these variables so our answer will still contain k and d.

Okay, now we'll break down the timing:

So she feeds her kitten 2 times every morning and 2 times every evening, which gives us a total of 4 times per day.

She also feeds the dog 1 time in the morning and 1 time in the evening, giving us 2 a day.

So now we just need to combine these timings with the variables.

she feeds the kitten 4 times daily, so we will multiply the amount by k to get 4*k or 4k.

We'll do the same with the dog and get 2*d or 2d.

Now we have an equation:

4k + 2d

She gives the kitten food (k) 4 times a day and gives the dog food (d) 2 times a day.

Now, we can deconstruct the answer choices and see if they match up with our equation.

A- 4(k+2d):

This equation looks like ours, but has parentheses, which means we have to multiply that 4 by everything inside them.

After doing that, we get:

4*k + 4*2d, or

4k+8d.

Close, but we only have 2d, so this one is not equal

B- 2d+4k

This one is pretty straightforward.

Our equation is 4k+2d, which means that they are equal.

C- (2k+d)+(2k+d)

In this one, we can simply combine like terms to get 2k+2k+d+d or

4k+2d.

This one is equal to ours.

D- (k+d)2

Just like in A, we will multiply everything inside the parentheses by 2, getting

2k+2d.

We need 4k, so this one is not equal.

Answer:

B and C

Explanation:

To help sum it up a little...

She feeds her kitten a total of 4 times in a day and her dog twice in a day.

To know how much food the animals had in a day you need to multiply the

amount of food they had for each time they were given food by the amount of times they were fed.

grams of food × amount of times fed

I hope that makes it easier to understandI tried to make it simple
