Step-by-step explanation:
Last one because it has an odd number of negative signs
<span>20 p/2 pounds = 20p/200p = 1/10</span>
Step-by-step explanation:



=> Solution in the set {-2,-1,0,1,2} is {-2,-1,0,1}
Hope you've understood the solution.
Consider factors of 42, then if the factors can be added or subtracted.
42 = 42 * 1
42 = 21 * 2
42 = 14 * 3
42 = 7 * 6
Since none of these can be added or subtracted to equal 15, no intergers satisfy these criteria.
