D = number of dogs washed
c = number of cats washed
d = (60 - 5c) / 7.50
The 7.50 should be underneath the brackets
Since BD and AC are diagonals of rectangle ABCD . ..hence they are equal..
AC = BD
3x+4 = 5x-50
2x = 54
x = 27

I used cymath.com. I highly recommend it. It shows you the steps to the problem you want to solve!
I hope this helps! :)
The last step is to solve for z
Answer:
0.22
Step-by-step explanation:
Let the events be:
A: the person is a woman
B: the person has high blood pressure
We want to find P(B/A), that is, the probability that a person has high blood pressure given that is a woman. We can use the following theorem:
P(B/A) = P(A∩B)/P(A)
P(A∩B) is the probability that a person is a woman and has high blood pressure. Given that there are 18 women with high blood pressure and 158 persons in total (81 + 77),
P(A∩B) = 18/158
P(A) is the probability that a person is a woman. Given there are 81 women and 158 persons in total,
P(A) = 81/158
P(B/A) = P(A∩B)/P(A)
P(B/A) = (18/158)/(81/158) = 0.22
Answer:
r u trying to look for the values of D and H?
D (3)(-9) = 0
D -27 = 0
D = 27
H - 24 = 4
H = 4 + 24
H = 28
