Answer 1

Resposta/Explicação passo-a-passo:

b)10xy-6xy-3xy

10 - 6 -3 = 1

c)5ab+7ab-2ab

5 + 7 - 2 = 10

d)-7,5abc+7,5abc

-7,5 + 7,5 = 0

e)10 bc-12 bc+5bc+4bc

10 - 12 + 5 + 4 = 7

g)2x+3x

2 + 3 = 5

h)6y-4y+5y

6 - 4 + 5 = 7

i)3a-6a-a

3 - 6 = -3

(essa eu não tenho certeza)

j)7b+4b-6b

7 + 4 - 6 = 5

k)8xy-4xy+4xy

8 - 4 + 4 = 8

l)-3p-7p+18p

-3 - 7 + 18 = 8
