Step-by-step explanation:
a + b = 90
a + c = 180
a) If a = x, the. we can write
x + b = 90 and x + c = 180
or
b = 90 - x
c = 180 - x
b) c - b = (180 - x) - (90 - x)
= 180 - x - 90 + x
= 90
Answer: 3/8
Step-by-step explanation:
Formula is,
P(A|B) = P(A and B) / P(B)
= (3/10) / (4/5)
= 3/8
I think is C or B
Because
3(x-2) = a+ 3x
3x 6 = a + 3x
3x+3x= 6
So
6=a + 6x
