Answer:
2. [tex]\frac{1}{2}x+125=450[/tex]
Step-by-step explanation:
We can use x to mean the number not known. Let's start by using [tex]\frac{1}{2}[/tex] of a number which would be [tex]\frac{1}{2}x[/tex] because the number here is signified by x. Then you would add 125 to that answer which would be shown by [tex]\frac{1}{2}x+125[/tex]. All of it equals 450, so it would be written as [tex]\frac{1}{2}x+125=450[/tex]
