Lol seems like elementary but 17.50 minus 9.50 equals 8 so the basic change is 8. X'D I cant believe this is college X'D
The answer is A I believe but I might be wrong.
When there are variables with exponents on the bottom you have to subtract the ones on the bottom from the ones on the top. Then if the exponent is negative you have to flip it.
4) n=12 this is because 45/4=11.25 and dividing 135 by 11.25 equals to 12
5) n=2.5 this is because 5/2=2.5 and multiplying 1 by 2.5 equals to 2.5
hope this helps :)
Product is multiplying. when you multiply a letter with a number you don't put any symbols so it would be 8c
