1 nickels =$0.05
1 dime= $0.1
let the number of nickels be x and that of dimes be y.
total number of coins is given by:
x+y=42
hence:
y=42-x.......i
total amount of cash will be:
0.05x+0.1y=3.30.........ii
substituting i in ii we get:
0.05x+0.1(42-x)=3.30
0.05x+4.2-0.1x=3.3
-0.05x=-0.9
x=-0.9/(-0.05)
x=18
hence the the number nickels is x=18, the number of dimes will be y=42-x=42-18=24
P = The kitchen is clean → TRUE
Q = The bedroom is clean → FALSE
1) If P is true, then Q is true. → False statement
2) Statement Q is true if and only if P is true. → False statement
3) Both p and q are true. → False statement
4) Statement P or Q is true. → True statement ⇒ Statement P is true.
The answer is: The statement "Statement P or Q is true" is true.
There you go! I really hope this helped, if there's anything just let me know! :)

A Because whenever you’re adding integers that have the same thing you keep the same signs in at the absolute value of each number
