The inverse of -9n is dividing by -9.

Find the arithmetic of the numbers 109, 113, 56, 87, 39, 68, 116, 79, 111, 91, 78, 121, 56
kvasek [131]
56 would be your answer because it’s the lowest number
The mean is not the same thing as median
mean=78+81+85+87=331
mean=331/4=82.75
median is the middle number, but you have a par set of numbers, so your median will be the middle numbers 78,81,85,87 , which are 81+85=166, 166/2=83
83 is your median
Your answer would be R=-5x-4+y
