What do i do do i subtract 168 and 23 and 7

first we need to add the total sum of the number of people seen. 168+23+7=198

then 198 divided by 60 is 3.3 and if your wondering why it isnt an answer without a decimal, then just think of three buses and one more bus filled with 20 or 30 people.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
