Question

calcular los valores de las sigiente expresiones cuando a=-10,b=15,c=-7 y d=2
a: a+b-(c+d) d: a-d-(a-c+d)+(b-a)
b: a-b-(c-d) e: a+5b-(c+d)°-(a+c)
c: a+d-(b-c) f: (a+b)+(c-d)-a+b)

ayuden me porfavor siii

Answer 1

a) -10 + 15 - (-7 + 2) =-10 +15 - (-5) = -10 +15 +5 = 10 b) -10 -15 - (-7 - 2) = -10 -15 - (-9) = -10 -15 +9 = -16 c) -10 +2 - (15 - -7) = -10 +2 - (15 + 7) = -10 +2 - (22) = -10 +2 -22 = -30 d) -10 -2 - (-10 - -7 + 2) + (15 - -10) = -10 -2 - (-10 +7 +2) + (15 + 10) = -10 - 2 - (-1) + 25 = -10 -2 +1 + 25 = !4 e) -10 + 5 (15) - (-7 +2)0 - (-10 + -7) = -10 + 75 - (-5)0 - (-17) = -10 +75 -1 +17 = 81 f) (-10 + 15) + (-7 -2) - (-10 + 15) = -5 + -9 - (5) = -5 -9 -5 = -19
