We should know so we know how to help

Answer 4

Equation:
\[\frac{2}{5}(3x-8)\]
Expand. This is done by multiplying each of the numbers inside by the outside number
\[\frac{2}{5}(3x-8)\]\[=\frac{2}{5}\times3x+\frac{2}{5}\times-8\]
Go from there

Answer 5

i am in 7th

Answer 6

Right that gives us 1.2x or 6/5x.

2/5 * -8 = ?

Answer 7

-3.2 i think

Answer 8

Yep, so that gives us -3.2 or -16/5.

So our answer's gonna be 6/5x -16/5

Answer 9

OK
this is basic math, you should know how to deal with parenthesis
like: 6(5+4) = either 6*5 + 6*4 or 6*9
but in case of variables it's different
like: 3(7+x) , you need to multiply 7 by 3, and multiply x by 3
3(7+x) = 21 + 3x
