Solve for x : 12x+5=10x−11 .(1 point)
x=
-16.5
So x = ???
x = -16.5
Are you sure?
I apologize for the mistake in my previous responses. Let's correctly solve for x in the equation 12x + 5 = 10x - 11.
12x + 5 = 10x - 11
Subtract 10x from both sides:
12x - 10x + 5 = 10x - 10x - 11
2x + 5 = -11
Subtract 5 from both sides:
2x + 5 - 5 = -11 - 5
2x = -16
Divide by 2 to solve for x:
x = -16 / 2
x = -8
Therefore, x = -8. Thank you for your patience.
After riding on the bus, Tran walked 30 minutes to get to her friend’s house. Her total travel time was 4 times as long as the bus ride. What equation does this situation model? Use t for the time of the bus ride.
Let's denote the time of the bus ride as t.
The total travel time is 4 times as long as the bus ride.
The time Tran spent walking is 30 minutes.
Therefore, the equation that models this situation is:
t + 30 = 4t
This equation states that the total travel time (t + 30) is equal to 4 times the duration of the bus ride (4t).
So I put 4t?
No, in the equation t + 30 = 4t, t represents the time of the bus ride. The equation t + 30 = 4t represents the situation where the total travel time (t + 30 minutes) is 4 times as long as the bus ride (t minutes).
You do not need to replace t with 4t in this equation. The equation as it stands correctly models the relationship between the bus ride time and the total travel time.
