Answer:
x=6
Step-by-step explanation:
-5(x - 2) = -20
first multiple 5 by x and -2
-5x 10 = -20
subtract 10 from 10 and -20
-5x=-30
then divide 5
x=6
Step-by-step explanation:
From the table we can make comparison between the distance travelled and the time taken. It can be seen that the time increases as the distance decrease.
If the car travels 700 miles in 0.5seconds and 600miles in 1.5secs, we can calculate the speed of the car using the formula;
v = change in distance/change in time
v = ΔS/Δt
v = 700-600/0.5-1.5
v = 100/-1
v = -100mi/hr
Since Speed = Distance/Time
-100 = 480/Time
Time = 480/-100
Time = -4.8s
Hence it will take the car 4.8seconds to travel 480miles.
Answer:
G(t)=12-2t
Step-by-step explanation:
Okay, first we need to find out how many gallons he lost, so we multiply 2 by 3 and get 6 gallons used.
Next, now knowing 6 gallons are left and 6 have been used we now add to get 12 gallons originally.
Then, now that we have the rate of change and the starting number we put together the equation to the way that best suits the question
Last, to check our work plug six into t next to the two and solve to get six gallons used,
I hope this helps you
