Question

Can some one put the answers out

Answer 1

Explanation:

1. -5(a - 9) = -5a + 45

2.
`(-8.3-(+2.7))/((1)/(5) ) = (-8.3-2.7)/(0.2) =(-11)/(0.2)=-55`

3.13p + 13 - p = (13p - p) + 13 = 12p + 13

4. -11b - 3(-4b + 1) = -11b + 12b - 3 = b - 3

5.

`-2n+(1)/(6)-4(1)/(2)n = (-2n-4(1)/(2)n)+(1)/(6) = [-(4)/(2) n-((8)/(2)+(1)/(2) )n]+(1)/(6) = -(4)/(2) n- (9)/(2) n+(1)/(6) =-(13)/(2)n\\+ (1)/(6)`

7.
`-(3)/(5)(20r-5)-(-6r) =-12r+3+6r = (-12r+6r)+3=-6r+3`

8.
`-(5)/(6)x+(4)/(9)+(2)/(3)x+(1)/(3)=(-(5)/(6)x+(2)/(3)x)+((4)/(9)+(1)/(3))=(-(5)/(6)x+(4)/(6)x)+((4)/(9)+(3)/(9))=-(1)/(6)x+(7)/(9)`
