Answer:

a)10  d) 10  g) 18  b)-8  e)7.2  c)10 = (-2)  f)3

Step-by-step explanation:

a)90 ÷ [(-5) + (-4)]= 90 ÷ [-9]

                           =10

(d) (57 - (-3)÷ [(-60) ÷ 10])= [60÷(-6)]

                                       =10

(g) (-25) - (-7)] ÷[(-2)-(-1)]= -18÷-1

                                    =18

(b) (-64) ÷[6-(-2)] = (-64) ÷8

                          = -8

(e) (12-48) ÷ 1-6) = -36÷ (-5)

                          = 7.2

(c) [{40 ÷ (-4)} = (-2)] = 10 = (-2)

(f) (-63) ÷ [(-20) + (-1)]​ = (-63) ÷ (-21)

                                 = 3​
