They are both correct becuase lets say it was a shirt that was $30 and it was 30% off. For Jasani it would be 30 * 0.7 which equals $9 then you would subtract this 30 - 9 = 21. For Hanna it would be 30 - 0.3(30) which equals $21. So in the end they are both correct!
Answer:
Step-by-step explanation:
7 books.................................3 magazines
14 books.................................6 magazines
21 books................................9 magazines
28 books..............................12 magazines
of course we ca do it
7/3=28/x
x=(3*28)/7=12
I belive this is the answer
x³ = 27/125; and
x = 3/5.
explanation:
Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us
x³.
The current voltage is 27/125; this gives us the equation
x³ = 27/125.
To solve this, take the cubed root of both sides:
∛(x³) = ∛(27/125)
x = (∛27)/(∛125)
x = (∛(3*3*3))/(∛(5*5*5))
x = 3/5
Answer:
-2,-2 minimum
Step-by-step explanation:
I just had a test on this
minimum because it is a minimum point it starts at the bottom
-2,-2 that is where the vertex is which is the point at the minimum
