Answer:

mean=average which means you add all of the numbers and divide by the number of numbers there are, which sounds pretty confusing, but i'll show you! 9+7+11+10+8=45, now you divide 45 by 5, which is how many numbers there are that we had to add. 45 divided by 5 is 9, which means the MEAN/average is 9!

Step-by-step explanation:

hope this helps!

72.2 is incorrect :( i don’t know how to solve this (Geometry)

Triss [41]

AC and DB are the same length. Set the two to equal each other and solve for y.

9y + 1 = 8y +17

Subtract 8y from both sides:

y + 1 = 17

Subtract 1 from each side:

y = 16

Now you know Y you can find the the length of DB:

DB = 8y +17 = 8(16) +17 = 128 + 17 = 145

EB is half of DB:

EB = 145 / 2

EB = 72.5

-10x—16=14 -16x -6 = 14

Alla [95]

Answer: No solution

Step-by-step explanation:

-10x-16=14

-16x-6=14

-10x-16=-16x-6

-10x+16x-16=-16x+16x-6

6x-16=-6

6x-16+16=-6+16

6x=10

x=10/6

x=5/3

-16(5/3)-6=

-80/3-6*3/3=

-80/3-18/3=

(-80-18)/3=-98/3 $\neq$ 14

Hence, there is no solution
