Mkey [24]3 years ago

What is did to solve this problem was i wrote this down to get this figured out. 
7x + 3y - 2 + 6x - 1 + y^2 

The first thing I did to this problem was i took 6x and change it to a -6x because I'm subtracting it from 7x which 7x - 6x is just x cause there is an understood 1 next to it. So i rewrote the problem as x + 3y - 2 - 1 + y^2

So then i took the -2 and subtract it to 1 which is -3

So the answer I have is x+3y-3+y^2 

Hope this helped! :)

snow_tiger [21]

Answer:

  • 5 runs

Step-by-step explanation:

Initial number is 64 players

<u>Number of players reduce twice every run and will be equal to 2 to reach the grand final</u>

  • 64*(1/2)^x = 2
  • (1/2)^x = 1/32
  • 2^-x = 2^-5
  • -x = -5
  • x = 5

Number of runs is 5

64 > 32 > 16 > 8 > 4 > 2

stealth61 [152]

Respuesta:

3x² + 5x - 2

Dado que :

Área del rectángulo, A = largo * ancho

Dimensión = 3x - 1; x + 2

Área = (3x - 1) * (x + 2)

Área = 3x² + 6x - x - 2

Área = 3x² + 5x - 2

How you know that the values of the digit in the numbers 1500,000 and 100,500 ate not the same
Sliva [168]

In this number 1500,000,

1 is at million place and 5 is at hundred thousand place

So, the value of 1 = 1 (1,000,000) = 1 million

And the value of 5  = 5 (100,000 ) = 500,000 = Five hundred thousand

In the second number 100,500

1 is at hundred thousand place and 5 is at hundred place

The value of 1 = 1 (100,000) = 100,000 = Hundred thousand

And the value of 5  = 5 (100 ) = 500 = Five hundred

Since the digits 1 and 5 both are at different places in both the numbers so 1,500,000 and 100,500 are not the same.
