Hi I need help to figure out... since I am not too sure about them. Hope it not too much nor confusing. Would greatly appreciate it..
1- What is the value of a ?
(1) a + b = 7 + b
(2) a2 = 49
a) Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.
b)Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.
c)Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.
d)EITHER statement BY ITSELF is sufficient to answer the question.
e)Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.
2-A household subscribes to a calling plan which charges 10 cents per minute for all domestic telephone calls and 35 cents per minute for all international calls. If 180 minutes of phone calls were made from the household, how many of these minutes were international calls?
(1) The total cost of domestic calls made from the household was $10.00.
(2) The total cost of all telephone calls from the household was $38.00.
a) Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.
b)Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

d)EITHER statement BY ITSELF is sufficient to answer the question.
e)Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.
3-What is the value of y^2 ?
(1) ( x + 3)( x - 3) = x^2 - y^2
(2) ( x + 3)( x + 3) = x^2 + y^2
a) Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.
b)Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.
c)Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.
d)EITHER statement BY ITSELF is sufficient to answer the question.
e)Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.
4-Is x > y ?
(1) x^2 > y^2
(2) 3 x - 7 > - 3
a) Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.
b)Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

5-Jack has a jar full of dimes and nickels, the total value of which is $10.00. What is the value of the nickels in the jar?
(1) There are exactly 65 dimes in the jar.
(2) There are 5 more nickels than dimes in the jar.
a) Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

6- Edmund works at a constant rate and assembles 18 clocks in 3 hours. How much less time would be needed to assemble the same number of clocks if both Edmund and Heinrich were working simultaneously and Heirich works at a constant rate and assembles 18 clocks in H hours where H > 0?
(1) Both Edmund and Heinrich assemble the same number of clocks every hour.
(2) It takes Edmund and Heinrich, working simultaneously, half as long to assemble the clocks as it takes Heinrich working alone.
a) Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.
