Question 200294: Multiple Choice: Match the reason with the proof given below.
Prove: If a*c = b*c and c ≠ 0, then a = b
1 a*c = b*c
2 a*c*(1/c) = b*c*(1/c)
3 a*[c*(1/c)] = b*[c*(1/c)]
4 a*1 = b*1
5 a = b
9.Choose the reason for line 1 of the proof
Identity Property for Multiplication
Associative Property for Multiplication
Property of Reciprocals
Multiplication Property of Equality

Question 199905: Hello, I need some help here. The following problem is getting me all messed up and I am not sure what I am doing wrong. The problem is: I have to
Solve the system of equations using the substitution method.
If the answer is a unique solution, present it as an ordered pair: (x,y). If not, specify whether the answer is "no solution" or "infinitely many solutions" and state how you arrived at that conclusion.
-7x + y = 4
2x + 8y = 0
Please help me!!!!!

Question 199542: What property is violated here?
“THE MISSING DOLLAR” SaveAs: TheMissingDollar
Three men went to stay at a motel, & the man at the desk charged them $30.00 for their room. They split the cost, paying $10.00 each.
Later, the manager tells the desk man that he overcharged the men – that the actual cost should have been $25.00. The manager gives the bellboy five one-dollar bills, and tells him to give it to the men.
The bellboy figures – these guys didn’t give me a tip, & there’s no way I can evenly split five dollars three ways, so he stuck $2.00 in his pocket, & returned $3.00 to the men.
Now, each man has paid $9.00 to stay in the room; [3 men] [$9.00 each] = $27.00.
The bellboy pocketed $2.00; [$27.00] + [$2.00] = $29.00.
[$29.00] – [$30.00] = - $1.00.
WHAT HAPPENED TO THE MISSING DOLLAR ?

Question 196046: Factor completely:
x^2 - 5x - 7x + 35 = x^2 - 12x + 35
2x^2 + 11x + 5
x^4y - 16y = x^4 - 15y
Thank you so much!: Factor completely:
x^2 - 5x - 7x + 35 = x^2 - 12x + 35
2x^2 + 11x + 5
x^4y - 16y = x^4 - 15y
Thank you so much!
