Correct answer: "Diagonal AC is congruent to itself by the Reflexive Property of Equality."
Insert the sentence above before the sentence "Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA)".
The congruence of two angles is already proved, so you need to prove that the corresponding pair of sides is congruent. Then you have 3 pairs of congruent elements for the Angle-Side-Angle (ASA) Theorem.
The final price is $135 , because
.10 × 150 = 15
150 - 15 = 135
Answer: x=−5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4−7x=31
−4+−7x=31
−7x−4=31
Step 2: Add 4 to both sides.
−7x−4+4=31+4
−7x=35
Step 3: Divide both sides by -7.
−7x
−7
=
35
−7
x=−5
It has two solutions.
The first solution is x = -7
The second solution is x = 1
Hope this helps!
