2(3x - 4) + 10 = 5(x + 4)solving equations from book (geometry common core)​

Mathematics
1 answer:
Aleks [24]3 years ago
7 0

Answer:

x = 18

Step-by-step explanation:

Given

2(3x - 4) + 10 = 5(x + 4) ← distribute parenthesis on both sides

6x - 8 + 10 = 5x + 20, that is

6x + 2 = 5x + 20 ( subtract 5x from both sides )

x + 2 = 20 ( subtract 2 from both sides )

x = 18

Tonya and Pearl each completed a separate proof to show that alternate interior angles AKL and FLK are congruent. Who completed
zalisa [80]

Answer:

Tonya proof is correct
and Pearl proof is wrong

Step-by-step explanation:

AKL and GKB are obviously congruent. But the reasons given are different, One of the justification is Vertical Angles Theorem, and the other is Adjacent Angles.

But the correct justification is the Vertical Angles Theorem, because the angles are Vertically away from each other, or the angles are at opposite sides of each other. Which is when Vertical Angles Theorem is applied.
Making Tonya correct since that was the answer he given.

The definition of Adjacent Angles is incorrect, this Theorem is used when the angles are Adjacent to each other. When the angles are on the same line as the other angle, is when the definition of Adjacent Angles is applied. Not in this situation
