Question

ad/c+ae/b=3(-15)/-5+3(4)/12=?????

Answer 1

$$
\tt
\Large\Large~~ad/c+ae/b\\
\Large=\frac{-3\times(-15)}{-5}+\frac{3\times 4}{12}\\
\Large=-3\times (3)+\frac{3\times 4}{3\times 4}\\
\Large=-9+1\\
\Large=-8
$$
Does this make sense?

Answer 2

not at allllllllllll ):

Answer 3

Your're trying to solve this, right?
$$
=\frac{-3\times(-15)}{-5}+\frac{3\times 4}{12}\\
$$

Answer 4

no

Answer 5

the numbers I gave go where the letters are in the problem I gave

Answer 6

you replace letters w/numbers.. your format of how ur wording things I completely don't understand

Answer 7

So a=3, b=12, c=-5, d=-15, and e=4?
And you're trying to solve this equation?

$$
=\frac{3\times(-15)}{-5}+\frac{3\times 4}{12}\\
$$

Answer 8

Do you agree that these are the same?

$$
\tt
\Large~~ad/c+ae/b\\
\Large=\frac{a\times d}{c}+\frac{a\times e}{b}\\
$$

Answer 9

don't understand ur format sorry

Answer 10

I am writing d/c as \( \dfrac{d}{c}\)
This is a fairly common way too write a fraction.
So, for example, 3/2 is the same as \( \dfrac{3}{2}\)
Still doesn't make sense?

Answer 11

no

Answer 12

ok, let's keep your format

ad/c+ae/b

=3(-15)/-5+3(4)/12, but (-15)/-5 = 3

So this becomes 3(3) +3(4)/12 = 9 + 3(4)/12

So far ok?

Answer 13

no. I got this next. 3(-15)/-5+3(4)/12=
-45/-5+12/12=
540/60

Answer 14

you don't distribut like terms. this is order of operations with rational numbers.. alg 1 homework

Answer 15

I have 10 questions if u don't care to stay on the line helping with all ten pleaseee?????

Answer 16

Close.

-45/-5 + 12/12
= -45(-12)/60 + 60/60
=(-45(-12)+60)/60
=(540 + 60)/60
=600/60
=10

Answer 17

Does this make sense?

Answer 18

whatd u do in the 2nd line????

Answer 19

yeah

Answer 20

I'm finding a common denominator, which is the common denominator between -5 and 12, which is 60.

Answer 21

oh ok yeah it makes sense, I have to copy that down real quick. then could u help with more please I have 9 questions more. if u help me with all ten ill give a best response

Answer 22

I would have done it a little different for that line. I would have done like this:

-45/-5 + 12/12
= -45/-5 + -5/-5
=(-45-5)/-5
=(-50)/-5
=10

Working with -5 is easier than that big number 60

Answer 23

tooi still understand it lol (: thanks. next question?

Answer 24

yep

Answer 25

bc/d-be/a=12(-5)/-15-12(4)/3 common denominator -15

Answer 26

you there?

Answer 27

just got back

Answer 28

yes, common denominator is -15.Good.

Answer 29

how do u solve it????? lol

Answer 30

ok so you have,

=12(-5)/-15-12(4)/3
=12(-5)/-15-12(4)(-5)/-15

Right?

Answer 31

yeahhh

Answer 32

But let's make this easier. Let's simplify before finding a common denominator:

=12(-5)/-15-12(4)/3
=12/3-4(4)

Do you see why?

Answer 33

no

Answer 34

=12(-5)/-15-12(4)/3

For the first term, -5/-15 = 1/3

and for the second term, 12/3 = 4

Answer 35

ok?????

Answer 36

So, instead of 12(-5)/-15, we can write 12/3

Instead of 12(4)/3, we can write 4(4)

Combine this and we get 12/3 - 4(4) = 4-16=-12

Answer 37

No need for finding denominators now

Answer 38

no I don't think u can take 5/15 12 times 5 =? divided by 15 you lost me on first step

Answer 39

i don't think your doing it right. no offense but i think you might be misinterpreting my questions

Answer 40

i could take a pic and post???

Answer 41

12(-5)/-15 = 12 times -5/-15 = 12 times 1/3 = 12 times 1/3 = 12/3 = 4

You know that "ab/c" is the same as "a times b/c right"?

Go ahead and post it.

Answer 42

camera keeps blurring cant. you really aren't making sense. maybe you could draw steps and answer??

Answer 43

with fraction bar --- instead of /

Answer 44

12(-5) 12
______ = ___ = 4
-15 3

Is this better?

Answer 45

yes ! (:

Answer 46

But does it make sense?

Answer 47

yeah but u messed up on writing the problem

Answer 48

ok, Tell me the correct problem
