Answer:
Tyler's - (-5 - 3y) + (3y) = -5
Han's - (x) + (-5 - x) = -5
Step-by-step explanation:
If we are going to use Tyler's first step then we would use x = - 5 - 3y and substitute it in the original simultaneous equation x + 3y = -5, becoming (-5 - 3y) + (3y) = - 5 giving an exact answer of - 5.
But if we are using Han's first step then we will still substitute into the original simultaneous equation but in 3y. It would become
x + (-5 - x) = - 5 which also gives us an exact answer of -5.
Thus proving that both first steps show the same solution of -5.

Answer:
z = -4050
Step-by-step explanation:
x × y × z
90 × 45 × z
4050 = -z
4050 = -z \ × -1
-4050 = z
Answer:
11.29.
Step-by-step explanation:
We are given that The mean length of six-year-old rainbow trout in the Arolik River in Alaska is 478 millimeters with a standard deviation of 38 millimeters.
We are also given that these lengths are normally distributed.
So, The highest value is at mean .(Refer the attached figure).
Formula : 
The 54th percentile of the lengths is 11.29.
