2) if silas added 5 years to his age he would be 39. how old is silas now? write as an equation and solve.

X + 5 = 39
                   -5 from both sides
x=39-5
x=34

He would be 34 years old, this equation represents it:
39-5=34
You set up the equation this way because if he added 5 years to his age that would be equivalent to +5, so to get his current age you just subtract five from 39

$2900

Step-by-step explanation:

Given: Amount lost in the month of January= $2500

The net worth at the  end of month= $400

therefore, the net worth at the beginning of the month= Amount lost in the month + Net worth at the end of the month=2500+400= 2900

the net worth at the beginning of the month= $ 2900

the final answer is $2900.

hope this helps, God bless
