Which inequality is true when n=4?

Nadusha1986 [10]

To find out which inequality is true, we need to plug in n=4.

$2n>6$
$2(4)>6$
$8>6$

And since 8 is really greater than 6, this inequality is true! :)

$n+3$
 $4+3 < 7$
$7 < 7$

7 is not less than 7. So this inequality is false.

$9- n \geq 13$
$9-4 \geq 13$
$5 \geq 13$

5 is not greater than or equal to 13, so this inequality is false

$\frac{n}{12} \geq 3$
$\frac{4}{12} \geq 3$
 $\frac{1}{3} \geq 3$

And 1/3 is not greater than 3, so this inequality is also false.

I NEED THIS DONE, PLEASE SHOW ALL WORK!! PICTURE 1 IS FOR QUESTION 3 AND PICTURE 2 IS FOR QUESTION 2. THANK YOU

Artemon [7]

Answer:

See explanation

Step-by-step explanation:

Question 1. Write two-column proof.

Statement Reason

1. $4x=8(x-2)$ Given

2. $4x=8x-16$ Distributive Property of Equality

3. $4x-8x=8x-8x-16\\ \\-4x=-16$ Subtraction Property of Equality

4. $x=4$ Division Property of Equality

Question 2.

Statement Reason

1. $m\angle SQR = 55^{\circ}$ Given

2. $m\angle PQS = 35^{\circ}$ Given

3. $m\angle SQR+m\angle PQS=m\angle PQR$ Angle Addition Postulate

4. $m\angle PQR=55^{\circ}+35^{\circ}\\ \\m\angle PQR=90^{\circ}$ Substitution Property of Equality

5. $\angle PQR$ is a right angle Definition of a right angle

6. $\triangle PQR$ is a right triangle Definition of a right triangle

Question 3:

Statement Reason

1. $\angle 1$ and $\angle 2$ are supplementary Given

2. $m\angle 1+m\angle 2=180^{\circ}$ Definition of supplementary angles

3. $m\angle 1=27^{\circ}$ Given

4. $27^{\circ}+m\angle 2=180^{\circ}$ Substitution Property of Equality

5. $27^{\circ}-27^{\circ}+m\angle 2=180^{\circ}-27^{\circ}\\ \\m\angle 2=153^{\circ}$ Subtraction Property of Equality
