Question

3. Se x = 10, calcule:
a) x+8 =
b) x-3 =
c) x + x =
d) 3x =
e) x.3=
f) x:2=
9) x: 4
h) 12+ ( x-8) =
i) (x+6):2=​

Answer 1

Resposta:

$a) \: 10 + 8 = 18 \\ b) \: 10 - 3 = 7 \\ c) \: 10 + 10 = 20 \\ d) \: 3 \times 10 = 30 \\ e) \: 10 \times 3 = 30 \\ f) \: 10 \div 2 = 5 \\ g) \: 10 \div 4 = 2.5 \\ h) \: 12 + (10 - 8) = 12 + 2 = 14 \\ i) \: (10 + 6) \div 2 = 16 \div 2 = 8$
