The total is 275 because 100% divided by 20% is 5 and if 20%= 55 then that means that 55 goes into 100% 5 times so you multiply 55 by 5 to get 275. Hope I helped! Please rate me as the brainliest!

The average of the first five multiple of 7 is
Black_prince [1.1K]

Answer:

b. 21

Step-by-step explanation:

The first five mutiples of 7 are:<em> 7, 14, 21, 28, 35. </em>You can get these by multiplying 7 to any integer.

  • 7x1 = 7
  • 7x2 = 14
  • 7x3 = 21
  • 7x4 = 28
  • 7x5 = 35

In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.

Let's add first.

7+14+21+28+35 = 105

Let's divided 105 by 5, which is the number of the multiples of 7.

105÷5 = 21

<em>The answer is 21.</em>

qaws [65]

Answer:

x=-2

Step-by-step explanation:

x-27 = 7x -15

subtract x from both sides

-27=6x-15

add 15 to both sides

-12=6x

divide both sides by 6

-2=x

x=-2
