Answer:

t = 5

Step-by-step explanation:

  1. Subtract 4 from each side, so it now looks like this: 3t = 15
  2. Divide each side by 3 to cancel out the 3 next to t. It should now look like this: t = 5

I hope this helps!

(A journey by bus takes 45 minutes at 60 km per hour. How fast must a car go to do the same
Vlad [161]

Answer:

The car must drive at 108 km/h to cover the same journey.

Step-by-step explanation:

Given that:

Time taken by bus journey = 45 minutes = \frac{45}{60} = 0.75\ hour

Speed of bus = 60 km/h

Distance of the journey = Speed * Time

Distance of the journey = 60 * 0.75 = 45 km

The car needs to cover 45 km in 25 minutes.

25 minutes = \frac{25}{60}\ hour

Distance = Speed * Time

45 = \frac{25}{60}*Speed

Speed = 45*\frac{60}{25}

Speed = 108 km/h

Hence,

The car must drive at 108 km/h to cover the same journey.

What is the solution in the equality -3x-42&gt;3?
Umnica [9.8K]
-3x-42>3
-3x>45
x<-15

I chose x<-15 because through the process of elimination, if it was an equality, x=-15. Since it is an inequality, when dividing both sides by a negative, the sign switches.
