The mean is the average.
Let A = mean
A = (18 + 14 + 9 + 6 + 3)/5
A = 50/5
A = 10
Ellie's mean time is 10 seconds.
I know the 3rd question the answer is rectangle
Answer:
The solution to the equation is
x = -4
Step-by-step explanation:
We want to find the solution to the equation
(1/4)x - 1/8 = 7/8 + (1/2)x
First, add -(1/2)x + 1/8 to both sides of the equation.
(1/4)x - 1/8 - (1/2)x + 1/8 = 7/8 + (1/2)x - (1/2)x + 1/8
[1/4 - 1/2]x = 7/8 + 1/8
x(1 - 2)/4 = (7 + 1)/8
-(1/4)x = 8/8
-(1/4)x = 1
Multiply both sides by -4
x = -4
Answer:
We conclude that the distance between the two numbers on a number line will be: 322
Step-by-step explanation:
Given the numbers
-212
-534
There can be a lot of ways to determine the distance between the two numbers on a number line like counting every number between them.
But, we can use a more efficient method in terms of determining the distance by taking the absolute value of the difference between those numbers.
so
Distance between the numbers:

Apply rule: -(-a) = a


Apply absolute rule: 

Therefore, we conclude that the distance between the two numbers on a number line will be: 322
