Answer:

k = -4
Step-by-step explanation:
Given system of equations are,
-3x-3y = h
-4x + ky = 10
We have to find the values of h and k such that system of equations has no solution.
The standard form of system of equation in two variables can be given by,


And condition for the system of equations has no solution is given by,

So, by comparing the standard form of equations with given equations, the condition such that system has no solution can be written as,


=> k = -4
and 



So, the value of h and k for above given system of equations is
and k = -4.

Answer:
h
Step-by-step explanation:
- Density of alcohol=79g/ml
- Density of water=100g/ml
We know
- if a object has higher d ensity than water then it would sink in water and if it has lower density than water then it float over water
Clearly
So alcohol would float over water
