Answer:
140 ounces of water and 105 ounces of 35% salt solution.
Explanation:
Let 
be the ounces of water that need to be added and 
be the ounces of 35% solution that need to to be added.
We know that the total of ounces of water and of 35% solution must be 245 ounces:
35% of is the salt, and since no salt is added with addition of liters of water, this must be equal to the amount of salt in the final 15% solution:
we solve for and get:
We put this value into and solve for to get:
Thus we have 140 ounces of water and 105 ounces of 35% solution.

Question 2
Answer:
5C 6D
Step-by-step explanation:
5, a^2 = b^2 + c^2
6,
A is wrong because two distinct lines intersect at 1 point only or 0 (they will never intersect when they are parallel)
B & C are wrong because lines contain infinite point
E is wrong because 2 parallel lines will never intersect, as the result, their common points = 0

Answer:
sqrt(41)
Step-by-step explanation:
The new point, A' has coordinates=(-3,2). The distance between them is sqrt((-8+3)^2+(6-2)^2)=sqrt(5^2+4^2)=sqrt(41)
