Function M described by M(x)= 3x+16 can be used to predict the circumference of the waist of a male in x inches who is obese .
Predict the circumference of a male’s waist whose inches are 49
would this be 3(49)+16=163 I hope I did this right

3x + 16 = 49
3x = 49  16
3x = 33 Divide both sides with 3
x = 11
