<span>The answer is 7. Seven is a prime number, which means that its multiples are 1 and itself (7): 7 = 1 * 7. To find out which one is a factor of 7, we should divide each of them by 7. 1/7 will be a decimal number and 7/7 = 1, which is a whole number. Thus, 7 will be a multiple of 7 and also a factor of 7.Hope this helps. Let me know if you need additional help!</span>
First, let's find the solution.
-2x + 3y = 8
Add 2x to both sides.
3y = 2x + 8
Divide both sides by 3.
y = 2/3x + 8/3
4x + 2/3x + 8/3 = -2
14/3x + 8/3 = -2
Subtract 8/3 from both sides.
14/3x = -14/3
Multiply both sides by 3/14.
x = -1
y = 2/3(-1) + 8/3
y = -2/3 + 8/3
y = 6/3, or 2.
The solution is (-1, 2) which lies in Quadrant II, because its outline is (-, +).
Answer:
.82 x 4 = $3.28
.82 = 1/4 pound, so you multiply by 4 (the reciprocal of 1/4) to get a whole.

Answer:
(a)
(b)
(c)NO
Step-by-step explanation:
GIVEN: Solution A is an 
acid solution. Solution B is a 
acid solution.
TO FIND: (a) Find the amount of Solution A (in mL) that must be added to 
of Solution B in order to produce a 
acid solution. (b) Find the amount of Solution A and Solution B (in mL) that can be combined in order to form a 
solution that is 
acid. (c) Does there exist a combination of Solution A and Solution B that is 
acid.
SOLUTION:
(a)
Let total amount of solution A added be 
Total amount of mixture 
As resulting solution is acid solution.
Amount of acid in final solution is sum of acid in both solutions
(b)
Let amount of Solution A be 
Amount of solution B 
As resulting solution is acidic solution
Amount of acid in final solution is sum of acid in both solutions
Amount of solution B 
(c)
No as concentration of final solution can not be greater than one with higher concentration.
