Answer:
Option A is correct.
4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5
Step-by-step explanation:
Given the expression: 
If n = -5
then, by substituting in given expression we get;
Option A:
4n + 8
Substitute the value of n = -5 we have;
Option B:
2n + 2
then;
2(-5) + 2 = -10 + 2 = -8
Option C :
then;
Option D:
n + 8
then;
-5 + 8 = 3
Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5
Answer:
x = 9/4
Step-by-step explanation:
Locate point G on segment DE so that DG = 1 and GE = 4. CG is parallel to AD, so ΔCGE ~ ΔABC. Corresponding sides are proportional.
AB/BC = CG/GE
x/1 = 9/4
x = 9/4
_____
<em>Additional comment</em>
Using the given triangles, you can write the proportion statement as ...
(9+x)/x = 5/1
We judge this to take more steps to solve, so we prefer the method shown above.
Answer:
81.167~
Step-by-step explanation:
You can find the mean (or average) of a set of numbers by adding them together and dividing the sum by the amount of values there are.
In this case, there are 6 values.
The total sum of the six values is 487.
To receive the mean, divide 487 by 6.
Answer:
Because the coin is tossed 7 times and you get 2 outcomes (head or tail) for each one.
Kim is X
Jordan= x+7
So J x 4=200
This means 4(x+7) = 200
x=43
43+7=50
50 x 4=200
so Kim is 43 and Jordan is 50.
