A car trip is 1/2h shorter that a bus trip. How long is the car trip if the bus trip is 3/4h?

1/4h

Step-by-step explanation:

If the time for the car trip is x, then given that a car trip is 1/2h shorter than a bus trip, it means that adding 1/2h to the time for a car trip gives the time for the bus trip.

Hence, the time for the bus trip

= (1/2 + x)h

since the bus trip is 3/4h, it means that

1/2 + x = 3/4

collecting like terms,

x = 3/4 - 1/2

= 3/4 - 2/4

= 1/4

Hence the car trip is 1/4h.

i have no answer for this maybe o 7 units

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.
