If we have a number represented by n, we have 20 is equal to, so 20=something. That something is "5 less than twice a number". 5 less than something means something-5, and something-5=20. Since 5 is less than twice a number, and twice a number is n+n=2n, we have 2n-5=20
Actually solving the problem, we can start by adding 5 to both sides, resulting in 2n=25. Next, we can divide both sides by 2 to get n=12.5
In an equilateral triangle all the sides are equal. This means that all the angles add up to 180 degrees.
Divide 180 by 3 and you get 60.
You want an exterior angle so you cut the angle in half ( it is now 30 )
Because the base and the line are parallel (form right angle if drew line connecting them) x is equal to
90-30=60
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.
