Charlotte's speed in meters per second is 2.5 meters per second.
What I did:
9 k per hour= (9/60)=per minute
9/60=0.15=15 m/m
0.15/60=0.025
0.025=2.5 m/s.
That is why Charlotte's speed in meters is 2.5 m/s.
The first step to solving this is to eliminate the opposites.
-5 × (-5) - ((3 - 4) × 2)
Calculate the difference from the expression in the parenthesis.
-5 × (-5) - (-1 × 2)
Multiply the numbers on the left side of the expression
25 - (-1 × 2)
Any expression multiplied by -1 equals the opposite,, which will change the expression to the following:
25 - (-2)
When there is a "-" sign in front of the parenthesis,, you must change the sign of each term in the parenthesis. This rule will make the expression look like the following:
25 + 2
Finally,, add the numbers together to get your final answer.
27
This means that the correct answer to your expression is 27.

Answer:
k = -5
Step-by-step explanation:
I think you mean GCF, or greatest common factor, in which case, yes, this is always true. An odd number has no factors of 2 or multiples of 2, so there is no way a factor of an odd number can be divisible by 2. Even if the even number has no odd factors, That would simply mean they have no common factors greater than 1, so the GFC would just be 1.
