Assuming that what you want me to solve is how much she paid for "extra use", the answer is she paid 20 times for the extra charge
47 - 32 = 15
20x .75 = 15

Step-by-step explanation:
Combining like-terms gives us 
Hope this helped!
I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132
Answer:
Step-by-step explanation:
Given that a survey found that women's heights are normally distributed with mean 63.4 in and standard deviation 2.2 in.
Let X be the random variable representing women heights.
P(58<X<80)
Z for 58 = -2.454
Z for 80 = 7.545
P(-2.454<Z<7.545) = 0.4945+0.5=0.9945
