Answer 1

Resposta:

Explicação passo a passo:

a)1×(1+7)-16:(1+3)=

a)1×(1+7)-16:(1+3)=

1×8-16:4=

8-4= 4

b)7×(9+5)-12:(4+2)=

b)7×(9+5)-12:(4+2)=

7×14-12:6=

98-2= 100

c)2×(7+1)-32:(7+9)=

2×(7+1)-32:(7+9)=

2x8-32:16=

16-2= 14

d)9×(3+7)-30:(9+6)=

9×(3+7)-30:(9+6)=

9x10-30:15=

90-2= 88

e)4×(6+1)-10:(1+9)=

4×(6+1)-10:(1+9)=

4x7-10:10=

28-1= 27

f)2×(4+6)-27:(3+6)=

2×(4+6)-27:(3+6)=

2x10-27:9=

20-3= 17

g)9×(1+3)-15:(9+6)=

9×(1+3)-15:(9+6)=

9x4-15:15=

36-1= 35

h)3×(6+3)-10:(2+8)=

3×(6+3)-10:(2+8)=

3x9-10:10=

27-1= 26

i)7×(8+3)-30:(9+6)=​

7×(8+3)-30:(9+6)=​

7x11-30:15=

77-2= 75

Espero ter ajudado ^^
