Question

5v-4\10=4\5

Answer 1

\[\frac{ 5v-4 }{ 10 }=\frac{ 4 }{5 } ?\]

Answer 2

\[5v-4\div10=\frac{ 4 }{ 5 }\]

Answer 3

or \[5v-\frac{4 }{ 10 }=\frac{ 4 }{ 5 }\]

Answer 4

ok

Answer 5

the first one

Answer 6

\[5v = \frac{ 4 }{5 } + \frac{ 4 }{ 10 }\rightarrow 5v = \frac{ 4*2 }{5*2 } + \frac{ 4 }{10 }\rightarrow v=\frac{ 12 }{10 } * \frac{ 1 }{5}\rightarrow v= \frac{ 6 }{ 25 }\]

Answer 7

is this a new problem?

Answer 8

yes

Answer 9

did you understand the last one?

Answer 10

yes

Answer 11

\[12-\frac{ 4 }{ 5 }(x+15)+4\]

Answer 12

\[12-(\frac{ 4x }{5 } + 12) + 4\rightarrow 12-\frac{ 4x }{5 }-12+4\rightarrow4-\frac{ 4x }{ 5 } or \frac{ 20-4x }{5 }\]

Answer 13

I'm assuming the expression is just supposed to be simplified.

Answer 14

ok

Answer 15

is this what you needed?

Answer 16
