B=A+5
10A+B=3(A+B)
Replace the B’s in the bottom equation with A+5s, because we know that’s the same thing from the top equation

10A+A+5=3(A+A+5)
11A+5=3(2A+5)
11A+5=6A+15
5A=10
A=2
Then B is 5 more than that so B=7
Your number is 27
**To double check**
When we double check this and see 7 is 5 more than then 2. Then 27 is three times what we get when we add the digits (2+7=9).

Answer:

  1. <u>0.25</u>
  2. <u>0.85</u>

Step-by-step explanation:

P (Triangle or Square) :

Find the value of each variable
