90 : 18
120 : 24
150 : 30
Y= kx (k being a constant)
10= k × 4 k=5/2
y= 5x/2 The answer is C.
a) a *5+5= 20
5a + 5 = 20
5a = 20 - 5
5a = 15
a = 15/5
a = 3
b) b/5 - 5 = 4
b/5 = 4 + 5
b/5 = 9
b =9*5
b = 45
The answer is A. just go by your placements
-16 - 4 = -1(16 + 4) = -1(20) = -20
Hope that helped :)
