Sever21 [200]
Okay. So, she buoyant 5.65 lbs of roast beef for $4.50. Multiply both of those numbers to get 25.425 or 25.43 when rounded to the nearest hundredth. So the total cost was $25.43. However, we now have to divide the amount by 6.5. 25.43/6.5 is 3.912 and other odd numbers or 3.91 when rounded to the nearest hundredth. The cost per sandwich was $3.91.

X+5+4-5=x+54<br>Help !!!​
max2010maxim [7]
  • Simplify both sides of the equation

=>x+5+4−5=x+54

=>x+5+4+−5=x+54

=>(x)+(5+4+−5)=x+54(Combine Like Terms)

=>x+4=x+54

=>x+4=x+54

  • Subtract x from both sides

=>x+4−x=x+54−x

=>4=54

  • Subtract 4 from both sides

=>4−4=54−4

=>0=50
