Question

m+18/m = 5/2

Answer 1

Hi

Answer 2

I know you have to do cross multiplication .

Answer 3

hello.

Answer 4

Well, you can do cross multiplication, but only if you set it up that way

Answer 5

Yea if you cross multiply you'd get
2(m+18)=5m
2m+36=5m
36=3m
m=12

Answer 6

m+18 5
---- = -
m 2

Answer 7

I see. Remember me telling you about using parentheses?

Answer 8

Yes I remember.

Answer 9

(m+18)/m = 5/2

Answer 10

Otherwise, it looks like something else

Answer 11

I become stuck at 2m+36=5m . . Yeah I forgot to put it again. :P

Answer 12

But now I understand it. Thanks.

Answer 13

When you originally posted the problem, this is what I saw:\[m + \frac{18}{m} = \frac{5}{2}\] That is why you must use parentheses

Answer 14

ohhhh. Sorry. Again. and one more.
4(d+4) = 3(2d+2)
which becomes 4d+16=6d+2
then becomes 10d+16=2 . . Then you would subtract. 2=16?

Answer 15

which becomes -14? then divide it by 10d?

Answer 16

You made a subtraction mistake

Answer 17

Answer 18

Actually, you made several mistakes

Answer 19

Was I supposed to add?

Answer 20

Oh... -.-

Answer 21

4(d+4) = 3(2d+2)
4d + 16 = 6d + 6

2d = 10

d = 5

Mmkay. If you help on this last one. which I think I got right.
5(f-9) = -3(11-f)
Isn't it 6?

Answer 31

5f-45 = -33+3f
2f = 12
f = 6

Correct
