Answer:

See explanation

Step-by-step explanation:

<u>Question 1. </u>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

<u>Question 2.</u>

                   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

<u>Question 3:</u>

                  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

Twice the difference of x and 5 is -33
Elden [556K]
2*(x-5) = -33, so x-5 = -16.5, so x = -11.5

This is assuming that "the difference between a and b" is a-b, which seems to be the accepted interpretation.
