Question

Please help me

3m/5 + a = b − 2m/5


A.5/3a − b


B.3/5a − b


C.3/5b − a


D.m = b − a

Answer 1

add 2m/5 to both sides

Answer 2

\[\frac{ 3m }{ 5 } + a = b - \frac{ 2m }{ 5 }\]
Add \[\frac{ 2m }{ 5 }\] to both sides
\[\frac{ 3m }{ 5 } + a +\frac{ 2m }{ 5 }\ = b - \frac{ 2m }{ 5 }\ +\frac{ 2m }{ 5 }\]
\[-\frac{ 2m }{ 5 }\ +\frac{ 2m }{ 5 }\] cancel out
Thus
\[\frac{ 5m }{ 5 } + a = b \]
Divide 5m by 5
\[m + a = b \]

Answer 3

yes :)

Answer 4

thank you both

Answer 5

I got 1 @edyscape

Answer 6

@mathessentials I got 1

Answer 7

explain

Answer 8

5m/5 I got just 1

Answer 9

5m/5 = m

Answer 10

you can cancel the 5
you CANT cancel the m - it's only in the numerator!

Answer 11

\[\frac{ 5m }{ 5 } =\frac{ 5 * m }{ 5 } = 1 * m = 1m = m \]
If you want 1 then you have to do this
\[\frac{ 5m }{ 5m } =\frac{ 5 * m }{ 5 * m } = 1 * 1 = 1 \]

Answer 12

the answer is d

Answer 13

@edyscape so it would be D.? @killerdime20

Answer 14

yes

Answer 15

Yes, it is D because
\[m + a = b\]
\[m + a -a = b - a\]
\[m = b - a\]
