Answer 1

Respuesta:

Explicación paso a paso:

a) 2 – (3 + 2) + 5 x 3 =

=2+−3+−2+15x

Combinar términos comunes:

=2+−3+−2+15x

=(15x)+(2+−3+−2)

=15x+−3

b) 2 – 3 + (2+5) x 3 =

=2+−3+21x

Combinar términos comunes:

=2+−3+21x

=(21x)+(2+−3)

=21x+−1

c) 14 - 9/ 3 + 2 =

= −5  / 3+2

=  −5 /5

=−1

d) (10+2.5) x 4 =

12.5 x 4 = 50

e) 14 - 9/3 + 2 =

=14−3+2

=11+2

=13

f) 35 - 4 × 3 + 15 ÷ 3 =

=35−12+ 15 /3

=23+ 15 /3

=23+5

=28

g) (35 – 4) x 3 + 15 ÷ 3 =

= 31x3+15÷3

= 93+5

=98

h) 5 + 3 x 1/3 =

= 8x0.3

= 2.4

i) (5 + 3) x 1/3 =

=8x1/3

= 8/3

=2.6

j) (5.3 – 4.3 + 3.5) x 6 =

=(4.5) x 6

=27

k) 5.3 – 4.3 + 3.5 x 6 =​
