Answer 1

Respuesta:

9.4

-8.265

-2.45

7.31

Explicación paso a paso:

1.25 + .40×2.3 -1.05 =

1.25 +(.4x2.3) -1.05 =

1.25 +9.2 -1.05 = 9.4

-2.4 ×3.6 +.75÷2=

(-2.4x3.6) + (.75÷2) =

-8.64 + .375 = -8.265

(((-7.5)÷2) ×1.8) +4.3 =

(-7.5÷2) x1.8 +4.3 =

((-3.75) x1.8) + 4.3 =

(-6.75) + 4.3 =

-6.75 + 4.3 = -2.45

5.25-2.1+8.3÷2=

(5.25-2.1) + (8.3÷2) =

(3.15) + (4.16) = 7.31
