The retail price is: $39
Step-by-step explanation:
The original price is $50. With a markdown of 22$, what is the new or retail price?
Subtract 22% of the original price from the original prices:
$50 - (50 * 22%) =
50 - (50 * .22) =
50 - 11 = $39
Proof:
11/50 = .22 or 22%

Answer:
Assuming the height is still 1 your answer would be 700
Step-by-step explanation:
<span>Simplifying
2x + -1y = 9
Solving
2x + -1y = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
2x + -1y + y = 9 + y
Combine like terms: -1y + y = 0
2x + 0 = 9 + y
2x = 9 + y
Divide each side by '2'.
x = 4.5 + 0.5y
Simplifying
x = 4.5 + 0.5y
Hope this helps :)

Average speed for Jaden’s train
= 130 km / (75/60) hours
= 130 km / 1.25 hours
= 104 km/h
Dani’s train travels from 15:15 to 18:30, which is 3 hours and 15 mins.
3 hours and 15 mins = 3.25 hours
Average speed of Dani’s train
= 312 km / 3.25 hours
= 96 km/h
Difference
= 104 - 96
= 8 km/h
