Ive got a soulution
the number is 3 times the sum of its digits
45 is added=4+5=9so,a common numbers in 3rd and 9th table
9,18,27,36,45...
27+45=72
2+7=9

4+5=9
Answer:
B. x = 5 and y = -13
Step-by-step explanation:
Subtract the constant on the left:
... (x +yi) = (9 -4i) -(4 +9i)
... = (9 -4 +i(-4-9))
... = 5 -13i
Matching real and imaginary parts, we see that ...
... x = 5, y = -13
First you can subtract 6h-8h =-2h
4-2h=60
-4-2h=-4
------------
2h=56
Now divide and you get 56/2 =28

Answer: 31.50 dollars</h3>
Work Shown:
30% of 45 = 0.30*45 = 13.50
You save $13.50 and the sale price is 45 - 13.50 = 31.50 dollars
An alternative is to compute
0.70*45 = 31.50
This works because if you save 30%, then you have to pay the remaining 70%
