Answer:
3x+2x+a=180 degree(being linear pair)
5x+25=180
5x=180-25
x=155/5
x=31
Step-by-step explanation:
This isnt a multi choice.. so you have to divide here.
P=21..........................
16
Since there is one "successful" outcome (rolling a 5) out of six possible outcomes (rolling a 1, 2, 3, 4, 5, or 6), the probability of rolling a 5 on one roll is P(roll one 5)=16.
Step-by-step explanation:
18(3x+1) = 54x+18
(6*9x) + (6*3) = 54x + 18
3(18x+2) = (6*9x)+(6*1)
(9*6x) - (9*2) = 18(3x-1)
54x+6 = (6*9x)+(6*1)
54x-18 = 18(3x-1)
