Because Z is directly proportional to X and inversely proportional to Y, therefore

When X=10 and Y=4, Z=47.5.
Therefore
k(10/4) = 47.5
2.5k = 47.5
k = 19.
That is,

When X=13 and Y=10, obtain
Z = (19*13)/10 = 24.7
Answer: 24.7
Answer:No
Step-by-step explanation:
first values is 3x+x = 4x
second value is x(2+1) = x(3) = 3x
since 3x!=4x . answer is no.
I think if you do 11 - 6 = 5 because it say that 6 not play so you would do 8 - 2 = 6 and then you do 6 + 5 = 11 because the says in all
It is in decimal form, can you give a little more feedback as to what you are applying?
Answer:
+4 and -4
Step-by-step explanation:
(x^2)-14=2
(x^2)-14-2=0
(x^2)-16=0
(x-4)(x+4)=0 = True
