Answer:

6(64/27)-11(16/9)

=6×64/27-11×16/9

=128/9-176/9

=128-176/9

=-48/9=-5 3/9=-5 1/3

Answer 2

Answer:

-23

Step-by-step explanation:

we multiply 6 with 64/27 we get 384/81

then we multiply 11 with 16/9 we get 176/99

so the equation is 384/81 -176/99 +4k/3 - 20 = 0

we transport it to the other side  

4k/3 = 20 -384/81 +176/99 =  20- 384/9 +176/11

4k/3 = 20 - 384/9 +16 = 36 - 384/ 9

4k = 36 - 384 / 9 * 3 = 36 - 384 / 3 = 36 - 128

4k = -92

k = -92/4 = -23
