How to i do 7/16÷(31/2÷1/2)

Start with what's inside the parentheses.

31/2 / 1/2

When dividing fractions, you are actually multiplying the reciprocal [reciprocal: what you get when you switch the place of the numerator and denominator]

So here's what that will look like:

31/2*2/1

Now multiply the numerators [first numbers] together, and the denominators [next numbers] together.

31/2*2/1=62/2

Now divide:

62/2=31

So now you've figured out what's inside the parentheses, place that in your original equation:

7/16 / 31

Use multiplying by the reciprocal to divide:

7/16*1/31

(the reciprocal of a whole number is 1/that number)

Multiply the numerators and the denominators:

7/16*1/31=7/496

And there's your answer.

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5
