subtraction property of equality
It would be 20 no? because there if it is x = x then x = 20 so 20 = x
same thing for all
(70*6000 = 420000) (6000*70 = 42000)
Bolded is the answer.
Answer:
y = 90
Step-by-step explanation:
If y varies jointly as x and z, then;
y = kxz
If y = 18 when x = 2 and z = 3
18 = k(2)(3)
18 = 6k
k = 18/6
k = 3
To get y when x = 5 and z = 6
y = kxz
y = 3(5)(6)
y = 15*6
y = 90
Hence the value of y is 90
