Step-by-step explanation:
25.2 + 800 - 427.43 x 2.4 ÷ 13
825.2 - 1025.832 ÷ 13
200.632 ÷ 13
= 15.44
Answer:
8
Step-by-step explanation:
plug in the number 4, it would be 5•4-12
Do 5•4=20
20-12=8
Percent change=change/original times 100
change=20-16=4
original=20
change=4/20 times 100=0.2 times 100=20
answer is 20%

Parallelograms have two pairs of equal angle measurements. For instance, Parallelogram 1 has angle pairs measuring 80°80° and 100°100°.
9. B
The statement is false. If a flowchart proof is difficult to construct, then a two-column proof should be used.
10. B
A long-term goal when writing a proof would be to prove a statement. A short-term goal would be to apply a postulate or theorem that helps to prove the statement.
11. C and B
1 and 4
2 and 3
12. B
Yes, L and V are vertical angles.
13. 39
14. B
Only Amy proved the theorem because she used postulates and theorems to construct a logical argument to show that the interior angles in a triangle add up to 180°180°.
