Answer:

x = -35

Step-by-step explanation:

  1. Add 3 to each side, so it now looks like this: 2/5x = -14
  2. Divide each side by 2/5 to cancel out the 2/5 next to x. It should now look like this: x = -35

I hope this helps!

Answer:

x =-35

Step-by-step explanation:

2/5x−3=−17

Add 3 to each side

2/5x−3+3=−17+3

2/5x = -14

Multiply each side by 5/2

5/2 * 2/5x = -14 * 5/2

x = -35

A car takes 4 hours to cover a distance, if it travels at a speed of 60 mph.
Katena32 [7]

Hello!

In order to solve this equation,we must first find out what distance is being traveled in 4 hours. If we travel 4 hours, at a constant speed of 60 miles,we must multiple those two numbers to find the distance travelled.

60x4 is 240.

This means we must divide 240 by 3 hours to find our constant rate of speed.

240 divided by 3 is 80.

This means, we would need to travel 80 mph to arrive to the same location in three hours.

x=80.

Hope this helps & good luck.

solniwko [45]

Answer:

7/12 + 2q/3

Step-by-step explanation:

11/12 - 1/3

= 11/12 - 4/12

=(11-4)/12

= 7/12

All the picture:

11/12  - 1q/6 + 5q/6 - 1/3

= 11/12 - 1/3 - 1q/6 + 5q/6

= 7/12 + 4q/6

= 7/12 + 2q/3
