What is the number halfway between 8516 and 8586?
madam [21]

Answer:

<u>8551</u>

Step-by-step explanation:

  • The midpoint of two numbers can be found by finding the mean of the two numbers
  • Midpoint = 8516 + 8586 / 2
  • We clearly see both numbers start with the digits '85' therefore their midpoint will also start with '85'
  • The remaining two digits on those two numbers should be added and divided by 2
  • ⇒ 16 + 86 / 2 = 102/2 = 51
  • Midpoint = <u>8551</u>

6x+6=-5+3x+17<br><br> I need help
yanalaym [24]

Answer:

Get all the terms with x on the left. Get all the terms without x on the right. Simplify by adding and subtracting the terms without x and adding and subtracting the terms with x. Finally divide to get the value of x.

Step-by-step explanation:

6x+6 =- 5+3x+17

6x+6 -6 =- 5+3x+17 -6

6x = 5+3x+11

6x = 3x + 16

6x - 3x = 3x + 16 -3x

3x = 16

3x / 3 = 16 / 3

x = 15/3 + 1/3

x = 5 1/3

x = 5.33333...
