Answer:
Given: It is given that  and .
To Prove: ABCD is a parallelogram.
Statements                                                                            
1.  and            
Reason: Given                                      
2.  are alternate interior angles      
Reason: Def of alternate interior angles
3.                                                 
Reason: Alternate interior angles are congruent
4.                                                              
Reason: Reflexive property
5.                                                  
Reason: SAS congruency theorem
6.                                                        
Reason: Corresponding Parts of Congruent triangles are Congruent (CPCTC)
7. ABCD is a parallelogram                                  
Reason: Parallelogram Side Theorem

Answer:
Step-by-step explanation:
Well is she wanted to make $80 “b” she would have to garden for 16 hours to make a maximum of $80
“C” if she wanted to make it out of babysitting she would have to work the same for 8 hours if she babysit 
Workout : b part = 10+10+10+10+10+10+10+10 Key:10=2
 :c part = 20+20+20+20. Key:20=2

Answer:
I am on my phone and this is kinda confusing and I don't know if your asking 10x^5 or 10^5 but the answer would be 
100,000 if it is 10 to the 5th power
If it is 10x to the 5th power then it's 100,000x
