Step-by-step explanation:
Perimeter of the given triangle = x + x + x + 7 = (3x + 7) units.
For this, we use the given info plus a bit of multiplying and subtraction
part 1)
we know that she's 25 y/m
so 5 minutes simply means 25 × 5

now we simply subtract this from 1000 (the original distance)

part 2)
the total time taken is even easier to find
all we have to do is divide 1000 by 25

Answer:
Original Price = $23
Step-by-step explanation:
$5.75 is the price after a discount of 75%
Let the original price be x and x is 100% of the price
5.75 = 100%x - 75%x
5.75 = 25%x
The new price is 25% of the original because you are subtracting 75%
25% is also written as 0.25
5.75 = 0.25x
x = 5.75/0.25
x = 23
The original price is 23
