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>

11. Find mZGJK.<br><br> Ġ<br><br> (5x + 8) H<br><br> (7x-16)
s2008m [1.1K]

Answer:

<h2>x = 2</h2>

Step-by-step explanation:

To find x, we need to solve the equation

G=H

Where G=5x+8 and H=7x-16.

Replacing expressions, we have

5x+8=7x-16\\16+8=7x+5x\\24=12x\\x=\frac{24}{12}\\ x=2

Now, we can find the value of each expression.

G=5x+8=5(2)+8=10+8=18\\H=7x-16=7(2)-16=14-16=-2
