Answer:X=21
Step-by-step explanation:
115+38+x = 174
153+ x= 174
X=174-153
X=21
The lunches cost 8.79 dollars per student and guessing that the teacher and student tickets cost the same, the passes are 17.83 dollars.
Answer:
<h2>Add 24 and 40</h2>
Step-by-step explanation:
3(8 - 2x) + 40 = 34 <em>use the distributive property a(b + c) = ab+ ac</em>
3(8) + 3(-2x) + 40 = 34
24 - 6x + 40 = 34 <em>combine like terms</em>
-6x + (24 + 40) = 34 <em>Answer: Add 24 and 40</em>
-6x + 64 = 34 <em>subtract 64 from both sides</em>
-6x = -30 <em>divide both sides by (-6)</em>
x = 5
Let's just start with x=20 and then do some algebra to it to make it all complicated
x = 20
2 * x = 2 * 20
2x = 40
2x - 13 = 40 - 13
2x - 13 = 27

See explanation
Step-by-step explanation:
16. Two parallel lines are cut by transversal. Angles with measures
and
are alternate exterior angles. By alternate exterior angles, the measures of alternate exterior angles are the same:

Then

17. Two parallel lines are cut by transversal. Angles with measures
and
are alternate interior angles. By alternate interior angles, the measures of alternate interior angles are the same:

Then

18. Two parallel lines are cut by transversal. Angles with measures
and
are alternate exterior angles. By alternate interior angles, the measures of alternate exterior angles are the same:

Then

19. The diagram shows two complementary angles with measures
and
. The measures of complementary angles add up to
then

Hence,

Check:

20. Angles
and
are vertical angles. By vertical angles theorem, vertical angles are congruent, so

Hence,

21.
and
are supplementary. The measures of supplementary angles add up to
so

Therefore,
