Answer:
see explanation
Step-by-step explanation:
73.
18 = 3x (divide both sides by 3 )
6 = x ( multiply both sides by
)
6 = 3x [
×
= 3 ]
divide both sides by 3
x = 2
74.
24 = 2x ( divide both sides by 2 )
12 = x ( multiply both sides by
)
12 = 2x ( divide both sides by 2 )
x = 6
75.
9 × x = 18
( divide both sides by 9
)
x = 2
76.
2 = x × ( multiply both sides by
)
2 = 4x ( divide both sides by 4 )
x =
Answer:
The solution of the system of equations is the point (-3,0)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Adds equation A and equation B
Find the value of y
The solution of the system of equations is the point (-3,0)
The parts that are missing in the proof are:
It is given
∠2 ≅ ∠3
converse alternate exterior angles theorem
<h3>What is the Converse of Alternate Exterior Angles Theorem?</h3>The theorem states that, if two exterior alternate angles are congruent, then the lines cut by the transversal are parallel.
∠1 ≅ ∠3 and l║m because we are: given
By the transitive property,
∠2 and ∠3 are alternate interior angles, therefore, they are congruent to each other by the alternate interior angles theorem.
Based on the converse alternate exterior angles theorem, lines p and q are proven to be parallel.
Therefore, the missing parts pf the paragraph proof are:
