Angle CBA = Angle DBC + Angle ABD
78 = Angle DBC + 47
78 -47 = Angle DBC
Angle DBC = 31
Answer:
3 5/6
Step-by-step explanation:
Lets work with the decimal part, 0.8(3)
The decimal would be 0.8333333......
let x be 0.833333....
10x would be 8.333...
100x would be 83.3333....
100x - 10x would be 75, because the repeating 3s will cancel out
90x = 75
75/90 = x
x = 75/90 = 15/18 = 5/6
The decimal is 5/6
Now we add back the whole number, 3, to 5/6
It would be 3 5/6

Overall Zane spent 178.25
2x26 = 52
3x19.26 =57.75
68.50
52 + 57.75 + 68.50 = 178.25
Solve for P over the real numbers usinf factorizing:
P^2 = 36/16
36/16 = 9/4:
P^2 = 9/4
Take the square root of both sides:
Answer: P = 3/2 or P = -3/2
