Hi!
The answer is the fourth one: y=3x
Hope this was helpful to you!!!
:)))
Y = k/x for some fixed number constant k
7 = k/9
k = 63
so Y = 63/x
14 = 63/x
14 x = 63
x = 63/14 = 9/2
Answer:
Final cost of the item is $19.55
Step-by-step explanation:
Expression representing the final cost of an item with original price = $p and discount = 15% will be,
Final cost = (p - 0.15p)
If the original price p = $23
By substituting p = 23 in the expression given,
Final cost after discount = 23 - (0.15)23
= 23 - 3.45
= $19.55
Therefore, final cost of the item is $19.55
64= 2.5x
64/2.5=
25.6 ounces is the weight of a case
