Hamster heaven charges an annual fee of $20 plus $2.50 for each day of hamster activities you attend. Hamster fun world charges
GarryVolchara [31]

Answer: I wouldn’t be able to make a linear system right now, but it would be better to use Hamster Fun if it were long-term, and Hamster Heaven if it were short-term.

Step-by-step explanation:

HH (Hamster Heaven) charges 20$ plus one a day, and HF (the other) charges 35 plus one a day, so if you went for 80 days for either one:

HH: 20 + (2.50 x 80) =

20+200: 220

HF: 35 + (1 x 80)= 115

If it were for only a day or two, it would be more efficient to use Hamster Heaven.

HELP HELP ME PLS I AM RUNNING OUT OF TIME!!!! HERE IS MY PROBLEM:
kramer

Answer:

Step-by-step explanation:

To write fractions with a common denominator, you will most likely need to scale some numbers up! I will explain how.

Let's try it with the fractions

2

3

and

3

12

12 is larger than 3, so we will have to multiply the 3 by some number to equal 12. (We are really finding the Least Common Multiple of the two denominators!) To do this, you have to multiply the 3 by 4, because 3x4=12. But now the numerator doesn't match the denominator. When you scale the denominator up, you have to scale the numerator up too! So the 2 must be multiplied by 4 also.

Now you have the following:

8

12

and

3

12

These fractions now have common denominators! Now they're all set for adding or subtracting fractions.

Try another:

2

6

and

3

5

: The least common multiple of 6 and 5 is 30. (the product of the denominators)

Transform each fraction by multiplying by "1":

2

6

⋅

5

5

=

10

30

and

3

5

⋅

6

6

=

18

30

One last problem:

4

9

and

7

6

What is the least common multiple of 9 and 6? Could you use 54? Absolutely, but it is not the LEAST number that you could use. How about 18? YES!

4

9

⋅

2

2

=

8

18

and

7

6

⋅

3

3

=

21

18

Ready to go...

Hope this helped!
