Heyyyy. How r uuu
I’m sooo bored
Answer:
After Two Hours.
Step-by-step explanation:
A simple way to do it is to:
1. Add 50+55, it is equal to 105. This is after one hour, so we know that it's more than this.
2. Add 50+55 to 105, This is after two hours, and we get 210, so we know that it has to be equal to 2 hours.
The easiest way to do this is to divide $460.000 by 100 and then multiply the anwser by 3. So...
$460.000÷100=$4600
$4600x3=$13800
3%=$13800
C) It doesn’t satisfy either the top or bottom equations.
When we plug them into the top equation:

Simplify:

Because the statement of -23 = -15 is wrong, the solution pair is wrong for the top equation.
When we plug them into the bottom equation:

Simplify:

9 = -8 is not a valid statement, so the pair doesn't satisfy both of the equations.
The answer is A ,because 18 divided by 2 is 9 then subtract that from the sum of 22 and 9 which is 31. Hope this helps!
