Answer:
82
Step-by-step explanation:
Plug in the variables into the equation and solve for B but remember your order of operations when solving multiplication/division before addition/subtraction.
B = 4*25-9*2
B = 100-18
B = 82
2:3 2:3 3:4 8:7 8:7 3:4 2:3 8:7 3:4
A=[1,4,5,7], B=[1,7,9,12]
AnB= [1,7]
