Question

Me ajudem por favor !!

1)resolva as equações abaixo:

A)1/27=3× b)100×=1000 c)35×+1=27 d)0,001×=1/100 ?

Answer 1

A) $3x= \frac{1}{27} \\ x = \frac{1}{27} /3 \\ x= \frac{1}{27}* \frac{1}{3} \\x= \frac{1}{81}$

B) $x= \frac{1000}{100} \\x=10$

C) $35x=27-1\\35x=26\\x= \frac{26}{35}$

D) $x= \frac{1}{100} /0,001\\x= \frac{1}{100}* \frac{1}{0,001} \\x= \frac{1}{0,1} \\x= \frac{10}{1} \\x=10$
