Answer:

2x-7

Step-by-step explanation:

So you have the equation 2(x-6)+5 first you are going to want to distribute the into parentheses. This means you are going to multiply every term in the parentheses by 2. So you multiply x by 2 and -6 by 2 to 2x-12. After you are gonna add 5 to 2x-12 since 5 and -12 are like terms. After adding you will get 2x-7 as your simplified equation.

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.

A hiker is walking down a mountain. She walked​ 5,978 feet in 17 minutes. In that​ time, she descended​ 1,024 feet from the top
olya-2409 [2.1K]

Answer:

63.5 feet/minute

Step-by-step explanation:

She first descended 1,024 feet in 17 minutes

Then she descended 500 feet in 7 minutes

The total feet descended is 1,024 + 500 = 1,524 feet

The total time to descend is 17 + 7 = 24 minutes

The average rate of change in altitude is  

Altitude descended / time

1,524 feet / 24 minutes

63.5 feet /minute

stellarik [79]

Figure out 5% of 30,000: .05 x 30,000 = 1,500

Multiply 1,500 by the number years, but subtract the first year (as you don't receive a bonus) : 1,500 x 39 =  58,500

Now add the bonus with the initial salary: 58,500 + 30,000 = 88,500.

THE ANSWER IS $88,500!!! :)
