Answers

Answer 1
Answer: 989,867 \approx 1,000,000
999 \approx 1000

\implies (989,867)/(999) \approx (1,000,000)/(1000)
(1,000,000)/(1000) = 1000

So the answer is approximately 1000.

3rd slot-7
4th- 6
5th-  5
6th- 4
7th- 3
8th-2
9th-1

so multiply them
9*8*7*6*5*4*3*2*1= 362880

362,880 ways

We could have  9 ways to pick the leader x 8 ways to pick the second place rider x 7 ways to pick the third place rider, etc.

So

9 x 8 x 7 x .....x  3 x 2 x 1  = 9!  = 362880  ways to arrange them

How to do −8n+4(1+5n)=−6n−14 and must show all your steps

Answers

This is a very easy question. All required information's are alreadypresent in the question. It only needs step by step procedure toultimately find the value of n. Now let us look into the given equation.
-8n + 4(1 + 5n) = -6n -14
-8n + 4 + 20n = -6n - 14
12n + 4 = -6n -14
12n + 6n = -14 - 4
18n = -18
n = - 18/18
   = -1
So the value of n in the given equation is -1.

Is anyone good at elimination method? I will give 10 points to the person that answer the question. :)Jill wants to solve the following system using the elimination method:

y = x + 8
y = 3x − 11

What number should the equation y = x + 8 be multiplied by to eliminate x?

Answers

To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.
-3! 
-3y=-3x-24
y=3x-11
-2y=-35
y=17.5
