A triangle with each side length 5 inches - there's only one of these.
Hello,
The answer is x= y-13 / 2 ( everything after the x= is a fraction)
How to solve;
Start by subtracting 13 from both sides of y=2x+13, we do this to get the x on 1 side
So now we have y-13=2x
Next divide both sides by 2, we do this to get x by it self.
y-13/2=x
Now we flip the problem and there you have it!
Edit: The x does not have a Pos or neg value, The only way to know what x is, is to solve for x.
Dylan's conclusion is not valid, because Dylan did not account for the other items purchased, only bagels.

Kindly check explanation
Step-by-step explanation:
Given the following :
Assum a normal distribution :
Mean (m) = 140 mm
Standard deviation (sd) = 20 mm
The percentage of people with blood pressure between 115 and 165 mm.
Zscore = (x - m) / sd
X = 115 mm
(115 - 140) / 20
-25/20 = - 0.625 = - 0.63
P(z<-0.63) = 0.2643
X = 165 mm
(165 - 140) / 20
25/20 = 0.625 = 0.63
P(z< 0.63) = 0.7357
0.7357 - 0.2643 = 0.4714 = 47.14%
B.) The percentage of people with blood pressure between 140 and 165 mm.
Zscore = (x - m) / sd
X = 140 mm
(140 - 140) / 20
0/20 = 0 = 0
P(z<0) = 0.5000
X = 165 mm
(165 - 140) / 20
25/20 = 0.625 = 0.63
P(z< 0.63) = 0.7357
0.7357 - 0.5000 = 0.2357 = 23.57%
C.) ___ The percentage of people with blood pressure over 165 mm.
X = 165mm
(165 - 140) / 20
25/20 = 0.625 = 0.63
1 - P(z< 0.63) = 0.7357
1 - 0.7357 = 0.2643 * 100% = 26.43%
