21 = 5n-2(n-3)

21 = 5n-2n+6

21-6 = 3n

n=15/3

n=5

5=n because you multiply -2 times n then -3 then you add -2n with 5n then subtract 6 from both sides and finally divide by 3

⦁ Show (2.3)(5.06) as a fraction multiplication problem and explain why the answer is in thousandths (three decimal places). 
astra-53 [7]

we have

(2.3)(5.06)

we know that

2.3=\frac{23}{10}

5.06=\frac{506}{100}

so

(2.3)(5.06)=(\frac{23}{10})(\frac{506}{100})

=\frac{11,638}{1,000}

=11.638

the answer is in thousandths, because the denominator of the multiplication of the two fractions is one thousand
