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
<span>PK=5x and KN=x2−14
</span>PK = KN
so
5x = x^2 - 14
x^2 - 5x - 14 = 0
(x -7)(x+2) = 0
x+2=0,x = -2
x-7=0;x = 7
so answer for x is 7
PK=5x = 5(7) = 35
KN=x^2−14 = 7^2 - 14 = 49 - 14 = 35
and
PN = PK + KN
PN = 35 + 35
PN = 70
answer
C. 70
