ProblemKong took 15\%15%15, percent fewer seconds than Nolan took to complete his multiplication timed test. Kong took 858585 seconds.
How many seconds did Nolan take?

Answers

kong: 15% 15x100=1,500

Nolan:85 seconds 85x2=170

then when you multiple kong by 15 and 100 it gives you 1,500 however nolan did of the seconds 85x 2 gives you 170 . in conclusion Nolan did 15x2=30 . which means Nolan did 30 seconds.

Here is a linear equation in x: 8x- 19 =-4-7x Is 5 a solution to the equation? That is,is x=5 a solution to the equation

Answers

8x-19=-4-7x
8x+7x-19+19=-4+19-7x+7x
15x=15
(15x)/(15)=(15)/(15)
x=1
To prove:
8-19=-4-7
-11=-11
Therefore x≠5

Answer:

X=5

If √6 is the geometric mean between 4 and another number, then the number is

Answers

If you have two numbers x, y.  The geometric mean is:  √xy

For 4 and x.  Geometric Mean =  √4x  and this is equal to √6

             √4x  =  √6     Square both sides.  The square root disappears.

               4x = 6 
                 x  = 6/4 = 3/2 = 1.5

The other number is 1.5.

 

What are the solutions to the equation x^2-8x=24

Answers

x^(2) - 8x = 24

Transposing the equation to give zero on the RHS:
x^(2) - 8x - 24 = 0

Since we can't factorise it directly, we must complete the square to yield any solutions:
x^(2) - 8x + ( (8)/(2))^2 - ((8)/(2))^2 - 24 = 0
(x^(2) - 8x + 16) - 16 - 24 = 0
(x-4)^2 - 40 = 0
(x-4)^2 = 40
x-4 = +/- √(40) ––> because square rooting yields a positive and negative solution.
x = 4 +/- √(40)
x = 4 +/- 2 √(10)

Correct me if I'm wrong anyone.
