I am not sure what you mean by placing the first digit, but I am going to assume you need help with this division problem.
We are dividing 315 by 9
First figure out how many times 9 goes into 31.
3 times right?
Now do 9 * 3
9 * 3 = 27
Subtract 27 from 31
31-27= 4
Now how many times does 9 go into 45?
5 times
Putting the 3 and the 5 together, we can conclude that the answer is 35

2/3x=8 X=12
3/2x=6 X=4
Step-by-step explanation:
Answer: 4m
Step-by-step explanation:
Note : midpoints divide a line into two equal parts.
To calculate the length of SA;
We can consider the large triangle QRS with
Two midpoints :
A on the line QS, QA = 4m ;
and B on the line RS with RB = 3m
Fron the definition of midpoint :
QS = QA + AS
where QA = AS
QS = 2QA = 2AS
Therefore,
QA = QS
4m = 4m
Is it 22.5 b/c 22.5 *2 = 45 and 22.5 +22.5= 45. or do u mean both numbers have to be the same
I know my math and your answer is going to be A.
