1 An airport employee checked a group of passengers through security on Thursday. On Friday, she checked three times as many passengers, and on Saturday she processed 5,000 passengers through security. In the 3 days, she processed 15,000 passengers. How many did she process on Friday? 10005000300020007500

7,500

Step-by-step explanation

x + 3x + 5,000 = 15,000

     4x  - 5,000 = 10,000

    4x =  10,000

               /4

x =        2,500

On friday, she checked 3x, so she processed 2,500 x 3 = 7,500 passengers.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
