360/9= 40
180-40= 140
140/2= 70
X=70
There are 120 6-digit numbers that can be formed
<h3>How to determine the combination of digits?</h3>
The digits are given as:
0,1,3,5,7 and 9
Since the number must be divisible by 10.
Then the number must end in 0
The other 5 digits can take any of the 0,1,3,5,7.
So, the number of combination is:
Count = 5! * 1
Expand
Count = 5 * 4 * 3 *2 * 1 * 1
Evaluate
Count = 120
Hence, there are 120 6-digit numbers that can be formed

Answer:
A. 7.5 cm
Step-by-step explanation:
3/4 = (x + 3)/(2x + 1)
3(2x + 1) = 4(x + 3)
6x + 3 = 4x + 12
2x = 9
x = 4.5
BC = x + 3
= 4.5 + 3
= 7.5 cm
