Which interval contains the median number of cars in line?
Drivers pay a toll to pass over a busy bridge, and
there are many toll booths that collect money. The city
manager counted the total number of cars waiting to
pay their tolls at 15-minute intervals during the day for
a total of 50 observations. The histogram below shows
the results.
10-20 cars
20-30 cars
30-40 cars
40-50 cars
Bridge Toll Booth Traffic
20

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
