"The sum of 4 and a number, divided by 2 is less than -6."​

, n < -16

Step-by-step explanation:

To write this into an inequality you need to recognize keywords. The first keyword is "sum" this means the two numbers must be added; so the first part of the inequality is 4+n. Then, it says the sum is "divided by" 2; this means both numbers must be put over two like . Finally, this is "less than" negative. Therefore, this must be an inequality with a sign opening towards -6. So the final answer is .

To solve the inequality isolate the variable. Multiply both sides by 2, so the new inequality is . Next, subtract 4 from both sides. The answer is n < -16.

step-by-step explanation:

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
