You do not need to flip the inequality sign when solving the following -5 ≤ 4r + 3.

Yes.

For inequality equation, you only flip the sign when you divide a negative number into both sides, here you will divide 4 on each side, so you won't flip the sign.

Consider the given parallelogram KLMN.

Prove: $\angle N \cong \angle L, \angle K \cong \angle M$

Statement Reason

1. $KL \parallel NM, KN \parallel LM$ Definition of parallelogram

2. $\angle K+ \angle N = 180^\circ$ Same Side interior angle theorem

$\angle L+ \angle M = 180^\circ$

$\angle K+ \angle L = 180^\circ$

3. $\angle K+ \angle N=\angle K+ \angle L$ Substitution property

$\angle L+ \angle M=\angle K+ \angle L$

4. $\angle N = \angle L$ Subtraction property of equality

$\angle M = \angle K$

Subtraction property of equality tells us that if we subtract some number from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.

5. $\angle N \cong \angle L$ Angle Congruence Postulate
