Let no. of pens be x.
Pens : x
Pencils: x+8
Total: 2x+8
Student takes 1 pen and 5 pencils.
Remainder: 2x+8 - 5 -1 = 2x+2
2x+2 = 26
2x= 24
x = 12 (original no. of pens)
x+ 8 = 20 (original no of pencils)
There are 12 pens at first and 20 pencils.
After 1 pen is taken, 11 pens are left.
After 5 pencils are taken, 20-5=15 pencils are left.

Answer: Expression :2.54 x
Number of centimeters in 12 inches : 30.48
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>1 inch = 2.54 cm
</em>
So, to estimate the number of centimeters in x inches:
2.54 x
Where "x" is the number of inches.
To estimate the number of centimeters in 12 inches, we simply replace the variable "x" (number of inches) by the number 12.
Mathematically speaking:
2.54 (12)= 30.48 centimeters
