Answer:
9 = 3^2
15 = 3 x 5
20 = 2^2 x 5
24 =2^3 x 3
A = 2^3 x 3^2 x 5 =8 x 9 x 5 = 360
Step-by-step explanation:
I don't know if you do this the same way I did, but..
The first step is to subtract 9 on both sides, like this.
13w + 9 = 178
-9 -9
You'll end up with:
13w = 169
I don't know if you need the answer or not but I'll help you out.
For the second step, divide both sides by 13w.
13w = 169
/13w /13w
w = 13
Hope this helped!
Answer:

Step-by-step explanation:
Given

Required
Determine the remainder
Write down the first digit i.e. 1. So, we have:

--------------------------------

Multiply that 1 by the divisor (1) i.e. 
Write down the result under the next digit i.e. (under 2)


--------------------------------

Sum 2 and 1 i.e 


--------------------------------
Multiply that 3 by the divisor (1) i.e. 
Write down the result under the next digit i.e. (under -3)


--------------------------------
Sum -3 and 3 i.e 


--------------------------------

Multiply that 0 by the divisor (1) i.e. 
Write down the result under the next digit i.e. (under 3)


--------------------------------

Sum 3 and 0 i.e 
Since there is no other computation to do, the result of the last sum is the remainder.
So:
