Is the following conditional true?

2 answers:

7 0

Yes, it is true. Ex. 3 x 9 = 27, 2 + 7 = 9.

If you happen to have a larger number say, 639, you might have to add the digits together multiple times before you have your answer so, 6 + 3 + 9 = 18, then 1 + 8 = 9, so it is divisible by 9.

What is the value of the expression 1/2 (m-2/3n) when m=3/2 and n= 1/2 ?

yawa3891 [41]

Answer:

B. $\frac{7}{12}$

Step-by-step explanation:

$m=\frac{3}{2}\\n=\frac{1}{2\\} \\\frac{1}{2} (m-\frac{2}{3} n)=\frac{1}{2} (\frac{3}{2} -\frac{2}{3} .\frac{1}{2} )\\=\frac{7}{12}$

So B is the correct answer.
