iren [92.7K]

Answer:

Theresa is 58.82 in tall

Step-by-step explanation:

Let 

x----------> Paul and Steve heights

y----------> Theresa height


we know that

1 1/2-------> 3/2---> 1.5

1 1/3-------> 4/3----> 1.33

 Paul says he is 16 inches shorter than 1 1/2 times Theresa's height

x=1.5y-16-------> equation 1


Steve says he's 6 inches shorter than 1 1/3 times Theresa's height

x=1.33y-6------> equation 2


equals 1 and 2

1.5y-16=1.33y-6

1.5y-1.33y=-6+16

0.17y=10----------> y=58.82 in


x=1.5y-16------> 1.5*(58.82)-16------> x=72.24 in


the answer is

Theresa is 58.82 in tall
