Answer 1

Respuesta:

Explicación paso a paso:

a) 7x(3+8)/7

=7x11/7

=77/7

=11

b)100/4x5

=100/20

=5

c)2.1-(3.5 + 2.1)+(5+3.5)

=2.1-5.6+8.5

=-3.5+8.5

=5

d)[20-(8-3)]-(9-4)

=(20-5)-5

=15-5

=10

e)3-0.5x2+4

=3-1+4

=2+4

=6

f)[(3+4)x5]-5+2x5

=(7x5)-5+10

=35-5+10

=30+10

=40

g)4.6+[20.7-(11.6+9.1)]

=4.6+(20.7-20.7)

=4.6+0

=4.6
