Medal and fan reward for ----help!!

Answer 1

\[\frac{ c+3d }{ -9 } =\frac{ -4c-e }{ -6 } \]
\[c+3d = -9 \frac{ -4c-e }{ -6 } = -9* \left( \frac{ -(4c+e) }{ -6 } \right) =-9*\frac{ 4c+e }{ 6 } =-3* \frac{ 4c+e }{ 2 }\]

Answer 2

\[c + 3d = -3*\frac{ 4c+e }{ 2 }\]

Answer 3

none of the above?

Answer 4

@gerryliyana it would be D, right?

Answer 5

Nooo

Answer 6

hold on my connection is poor

Answer 7

\[(c+3d)*2 = -3(4c+e) = -12c - 3e\]
\[2c + 6d = -12c - 3e\]
\[2c+12c = -6d - 3e\]

Answer 8

\[14c = -6d - 3e\]

Answer 9

\[c = \frac{ -6d-3e }{ 14 }\]

Answer 10

or
\[c = \frac{ -3e-6d }{ 14 }\]

Answer 11

it would be B

Answer 12

Yay, one more.

Answer 13

it's b

Answer 14

you are muslim, right?

Answer 15

Answer 17

7klm-10l+m-4=4l+7m+2
7klm = 4l+7m+2 + 10l -m+4
7klm = 4l+10l+7m - m+ 2+4
7klm = 14l +6m+6
k = ( 14l +6m+6)/7lm

Answer 18

It must be C

Answer 19

its correct

Answer 20

ok
