What is the value of x in the equation 34x+2=54x−6 ?

elixir [45]

Answer:

The value of x in the equation is: $x=\frac{2}{5}$

Step-by-step explanation:

Given the equation

$34x+2=54x-6$

Subtract 2 from both sides

$34x+2-2=54x-6-2$

$34x=54x-8$

Subtract 54x from both sides

$34x-54x=54x-8-54x$

$-20x=-8$

Divide by both sides by -20

$\frac{-20x}{-20}=\frac{-8}{-20}$

$x=\frac{2}{5}$

Therefore, the value of x in the equation is: $x=\frac{2}{5}$

Answer:

Step-by-step explanation:

Given the data:

13 15 14 16 12

The point estimate of the population mean will be :

ΣX/ n

X = Given data points

N = sample size

ΣX = (13 + 15 + 14 + 16 + 12) = 70

N = 5

Hence,

ΣX/ N = 70 / 5

Point estimate of population mean = 14
