Mathematics

Answer:

e= -2

Step-by-step explanation:

To solve for e, we need to get e by itself. To do this, we need to move all the numbers to one side of the equation, and all the variables to the other

9e-7=7e-11

Add 7 to both sides

9e-7+7=7e-11+7

9e=7e-4

Subtract 7e from both sides

9e-7e=7e-7e-4

2e= -4

Now all the numbers are one sides, and the variables are on the other. e is still not completely by itself, it is still being multiplied by 2. To reverse this, divide both sides by 2

2e/2= -4/2

e= -2

7, you divide 325 by 48. You get 6.77... since this is a real-world problem, you can’t have 6 and 2/3 buses so you round.
