Answer:
12
Step-by-step explanation:
x=ky
note:that k is a constant
'I have no alpha symbol in my keyboard'
you must express the equation in x=y but where = sign is put the alpha symbol first
since x=18 and y=3.6 we can find the value of the constant 'k'
18=3.6k
k=5
then find the value of y
y=?
x=60
so
5y=60
y=12
