Justin 100/12.61 = 7.93 m/s
shawn 200/26.38 = 7.58 m/s
shawn is faster
Note: The expression is missing. Consider the expression is 
.
Given:
The expression is
To find:
Factor form of the given expression by using GCF.
Solution:
We have,
Factors of each term:
The common factors are 2, 2 and 2. So,
Taking out the greater common factor (GCF) in the given expression, we get
Therefore, the required expression is 
and the correct option is C.
The answer is 1.5 I think
To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.
Multiply equation 1 by 2
This will give 4x-2y=14
Now we can get rid of y by subtracting 2 from 1
This will give x=9
Plug back in to either equation, i will use equation 2
3(9)-2y=5 simplify
-2y=-22 solve
Y=11
