schepotkina [342]

Answer:

Nancy paid 2.98 per gallon of gasoline.

Step-by-step explanation:

Mean of four numbers a ,b, c, and d is 8 and mean of seven
Nana76 [90]

Answer:

  • 17 1/3 or 17.33

Step-by-step explanation:

<u>Mean of four numbers a, b, c, and d is 8:</u>

  • (a + b + c + d)/4 = 8  
  • ⇒ a + b + c + d = 32

<u>Mean of seven numbers x, y, z, a, b, c and d is 12:</u>

  • (x + y + z + a + b + c + d)/7 = 12

<u>Substitute the sum of 4 numbers:</u>

  • x + y + z + 32 = 7*12
  • x + y + z = 84 - 32
  • x + y + z = 52

<u>Mean of x, y and z is:</u>

  • 52/3 = 17 1/3 or 17.33

vekshin1

Answer:

The correct answer is C) 10z(x − 2y)

Step-by-step explanation:

To find this, we look for the greatest common factor of those two numbers. Each can be divided by 10 and each have a z. So we divide each term by 10z and put that on the outside of the parenthesis.
