Answer:

x > 1

Step-by-step explanation:

15 - 1 = 14

The inequality is 15 - 1 < 14, but this is incorrect. 14 can not be less than 14. In order for the left side to be less than 14, the x value (currently representing 1) should be larger than what it currently is to make the statement true.

Therefore, x>1

yuradex [85]

Answer:

the value of c = 32.13

Step-by-step explanation:

all you had to do was take one of the options and divide it by 2.1 and you'll know you have to right answer when it equals 15.3 but just remember if you are dividing by a smaller number the numerator has to be a bigger number to be able to equal whatever is on the other side of the equals symbol.
