Solve 3y + 11 = - 16​
astra-53 [7]

Answer:

y=-9

Step-by-step explanation:

So we have the equation:

3y+11=-16

To solve for y, subtract 11 from both sides. The left will cancel:

3y=-27

Divide both sides by 3. The left again cancels:

y=-9

So, the answer is -9.

And we're done!

I hope this helps!

Tom travels along the M1 from Leicester to London which is a distance
Gemiola [76]

Tom did not break the 70mph speed limit of M1.

To know if Tom breaks the <em>speed limit </em>of the M1, we must first calculate Tom's speed and compare it to M1's speed limit.

Using the formula below,

  • s = d/t............... Equation 1

Where:

  • s = Tom's speed
  • d = distance from Leicester to London
  • t = time taken to travel from Leicester to London

From the question,

Given:

  • d = 143 miles
  • t = 8:25 to 10:15 = 2 hours 10 munites = (2+10/60) = (2+0.17)
  • t = 2.17 hours.

Substitute these values into equation 1

  • s = 143/2.17
  • s = 65.899 mph.

Hence, Since Tom's speed is less than the M1 speed limit, Tom did not break the 70mph speed limit of M1.
