Question 357129: The function H described by H(x)=2.75+71.48 can be used to predict the height in cm of a woman whose humerus is x cm long Predict teh height of a woman whose humerus is 30cm long
I believe that I am making this harder than it really is but I am so stumped
30(x)=2.75x+71.48
30(x)=74.55
x=2.485
Am I anywhere close

Simply plug in x=30 to get


H%2830%29=2.75%2830%29%2B71.48=82.5%2B71.48=153.98


So her height is 153.98 cm (which is about 5 feet 1 inch)
