40%*2=80 I hope I helped!
Since the discount is 20%, we know that $24 is 80% or 4/5 of the original price of the shoes. Divide the $24 by 20%, and you get $6. Add that to $24, and you get the original shoe price: $30. You can verify by Multiply 30 by 80%, which comes out to the discount price-$24.
You have to rotate it around (0,1) by 90 degrees

c or a
Answer:
d = 5t + 20
Step-by-step explanation:
d represents the distance and t represents the time, in hours
Let he equation which model this situation ⇒ d = a t + b
Where a and b are constant.
Let the gas station is the starting point
So, at gas station t = 0 , d = 20
∴ 20 = 0 * a + b ⇒ b = 20
When he reaches home 2 hours later notes that he has traveled 30 miles.
and with substituting with b = 20
∴ 30 = 2 * a + 20
2a = 30 - 20 = 10 ⇒ a = 10/2 = 5
∴ d = 5t + 20
The equations that can be used to model this situation <u>d = 5t + 20</u>
