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.
No, its only a repeating decimal is the numbers repeating are the same each time

Mrs Hamilton's commision
175000 x 0.04 (4%) = 7000
Mrs Hamilton received 4725
7000 x 0.01 = 70 (1%)
4725 / 70 = 67.5%
She received 67.5% of her total commission
David's Computer = C
Working
1080 x 0.8 (80%) =864
864 x 1.08 (108%) = 933.12
The computer cost $933.12 dollars
Suzanne's sweater = B
$40 / 100 = 0.4 (1%)
40 - 25 = 15 (difference)
15 / 0.4 = 37.5%
Suzanne received a discount of 37.5%
The unit rate is 
pounds per person.
Step-by-step explanation:
Given,
Quantity of candy Pablo have = 
pounds
Number of people = 4
