Answer:
y = 4
Step-by-step explanation:
Given that y varies jointly with x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 16 when x = 4 and z = , that is
16 = k × 4 × = 2k ( divide both sides by 2 )
8 = k
y = 8xz ← equation of variation
When x = 2 and z = , then
y = 8 × 2 × = 16 × = 4
Answer:
A -) E -) I -) F -) C -) H -) K -) Escape!
Step-by-step explanation:
I calculated it, so shouldn't be wrong but tell me if it is.
60 divided by 48 equals 1.25
