Alex has 3 pens in his pencil case. This is 25% of the number of pens that he has How many pens does Alex have altogether?​

12 pens

Step-by-step explanation:

25% basically means 25/100 which is simplified to 1/4. Now if 3 pens are 1/4 of all the pens, then you multiply 3 by 4 to give you 12 pens in all.

Alex has 12 pens altogether !

Step-by-step explanation:

- 25% = 25/100

- 25% × 4 = 100%

- 3 × 4 = 12

E5x-32=96. No solutions found. Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : e^5*x-32-(96)=0. Step by step solution : Step 1 :Equation at the end of step 1 : e5x - 128 = 0. Step 2 : Solving a Single Variable Equation : 2.1 Solve e5x-128 = 0. 

Simple anwser would be 0
