Answer: X - 5 ÷ 15
Step-by-step explanation: The first step to algebra is to collect like terms. Since X is an a variable, we cannot solve X - 5. But we can solve 5 + 10, since those are both numbers. 5 + 10 is 15. So therefore, your simplified expression would be X -5 ÷ 15.
Hope this helps! Please correct me if I'm wrong! :D
Our original value is $1,800. Every 7 years that value doubles, so at 7 years, our value would be $3,600. At 14 years, the value would be $7,200. At 21 years, the value would be $14,400. At 28 years, the value would be $28,800. At 35 years, the value would be $57,600. At 42 years, the value will be $115,200.
I hope this helps!
