h is a variable. Basically, h can be any number. For example,

Just replace h with any number you want

13 x 1 = 103
13 = 103, this is false because 13 does not equal 103.

Answer 24

ok the one that i was wondering about thirteen multiplied by h is one hundred and four can u explain that one

Answer 25

Okay, so lets focus on the first part of this word problem.

It's saying thirteen is being multiplied by h. Basically, h is a variable. H can be any number, we don't know what h is currently, but we do know it's being multiplied by h.

So, "Thirteen multiplied by h," would be: 13 x h <--

Now this is equal to 104.

13 x h = 104 <-- Because the equation tells us 13 times h is equal to 104.

Answer 26

how do you come up with h is equal to 104 ?

Answer 27

Because, " thirteen multiplied by h is EQUAL TO ONE HUNDRED AND FOUR."

Answer 28

so do i have to find a number that is multiplied by 13 to make 104

Answer 29

Yes! :D You're getting it!

Answer 30

13 x h = 104
13 x 1 = 13 <-- this is not 104
13 x 2 = 26 <-- this is not 104.

Answer 31

ok so would it be 8

Answer 32

Yes! Because 13 x 8 = 104!!! :D

Answer 33

because 13 x 8 1s 104

Answer 34

Mhm. You see, it's easy!

Try this one:

5 x y = 25

Answer 35

ok 5x5=25

Answer 36

Yes! So y is just any number that can be multiplied by 5 to equal 25.
