The sum of three numbers is 855. One of the numbers, x, is 50% more than the sum of the other two numbers. What is the value of
Snowcat [4.5K]

Answer:

The value of x = 513

Step-by-step explanation:

Let x, y, and z be the three numbers

Given

x+y+z=855

Assuming x be the number which is 50% more than the sum of the other two numbers.

i.e.

(150)% of (y+z) = 1.5(y+z)

                y + z = x/1.5

As we know that

x + y + z = 855

substituting y + z = x / 1.5 in the equation

x+\frac{x}{1.5}=855

Multiply both sides by 1.5

x\cdot \:1.5+\frac{x}{1.5}\cdot \:1.5=855\cdot \:1.5

1.5x+x=1282.5

2.5x=1282.5

Divide both sides by 2.5

\frac{2.5x}{2.5}=\frac{1282.5}{2.5}

x = 513

Therefore, the value of x = 513

Find the zeros of polynomial x^2-3
Yakvenalex [24]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The required zeroes are ~

\boxed{ \boxed {\sqrt{3}} \:  \:  and  \:  \: \boxed{- \sqrt{3} }}

\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}

Let's equate the given polynomial with 0, to find its roots ~

that is ~

  • {x}^{2}  - 3 = 0

  • {x}^{2}  - ( \sqrt{3} ) {}^{2}  = 0

  • (x +  \sqrt{3} )(x -  \sqrt{3} ) = 0

there are two cases,

Case # 1 - when (x + √3) = 0

  • x +  \sqrt{3}  = 0

  • x =  -  \sqrt{3}

and

Case # 2 - when (x - √3) = 0

  • x -  \sqrt{3}  = 0

  • x =  \sqrt{3}
