How many hours did they drive in all explain why

The Jacobys drove 19 1/2 hours from Monday to Thursday.

Step-by-step explanation:

I started your problem by simply adding all of the hours up.

However, if you're like me, then you might not have a calculator that can work with fractions at hand right now or be able to add them up without second-guessing yourself on your own.

So, if you run into this problem then you can take the fraction part of the problem and just work it like a division problem.

3/4 = .75

1/4 = .25

Then, you can take the respective decimals, and bring them back to their whole number.

5.75

4.75

2.25

6.75

Then just add them all up:

5.75+4.75+2.25+6.75= 19.5

Now, if you need to revert it back to a fraction it could get tricky again. Luckily, this time we got an easy one! .5 which equals 1/2.

So, your answer would be 19 and 1/2.

*** If this answer is wrong I sincerely apologize. I believe it is correct but we all make mistakes.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
