Question

I really help worth these question.

Answer 1

`(7)/(3)`

Explanation:

Given that,

p = -6,

q = 6

r = -19

Plug in the above values to evaluate the expression,
`((q)/(2) - (r)/(3))/((3p)/(6) + (q)/(6))`

`((6)/(2) - ((-19))/(3))/((3(-6))/(6) + (6)/(6))`

`((3)/(1) - ((-19))/(3))/((-3)/(1) + (1)/(1))`

`((9 -(-19))/(3))/(3 + 1)`

`((28)/(3))/(4)`

`(28)/(3)*(1)/(4)`

`(28*1)/(3*4)`

`(7*1)/(3*1)`

`(7)/(3)`
