Question

Evaluate the expression shown for x = 9. -5/6 x +7

Answer 1

Substitute 9 for x in -5/6 x +7
(-5/6) (9) + 7
Now solve
(-5/6) (9) + 7
-7.5 + 7 = -0.5

Your answer is -0.5 or -1/2

Answer 2

`-(1)/(2)`

Explanation:

Here, the given expression,

`-(5)/(6)x+7`

Put x = 9 in this expression,

`=-(5)/(6)(9) + 7`

`=-(5(9))/(6) + 7`
`\because (a)/(b)* c=(ac)/(b)`

`=-(45)/(6)+7`

`=(-45+42)/(6)` ( adding fractions )

`=(-3)/(6)`

`=-(1)/(2)`
