Which value for x makes the sentence true?

Marianna [84]

Step-by-step explanation:

$11x - 6 = 7x + 2$

First, let's move all of the terms with an $x$ to the left-hand side of t he equation, and everything else to the right-hand side of the equation.

$11x - 7x = 2 + 6$

$4x = 8$

Next, let's divide both sides by $4$ to isolate the $x$ variable by itself on the left-hand side of the equation:

$\frac{4x}{4} = \frac{8}{4}$

$x = 2$

1/2(x-4)=1/3(x+2) Helppp plsss will give brainilist

melamori03 [73]

Answer:

x= 16

Step-by-step explanation:

combine multiplied terms into a single fraction

$\frac{1}{2} (x-4)=\frac{1}{3} (x+2)$

$\frac{1(x-4)}{2} =\frac{1}{3} (x+2)$

Multiply by 1

$\frac{1(x-4)}{2} =\frac{1}{3} (x+2)$

$\frac{x-4}{2} =\frac{1}{3} (x+2)$

Combine multiplied term into a single fraction

$\frac{x-4}{2} =\frac{1(x+2)}{3}$

Multiply by 1

$\frac{x-4}{2} =\frac{x+2}{3}$

Multiply all terms by the same value to eliminate fraction denominators

$6*\frac{x-4}{2} 6(\frac{x+2}{3} )$

cancel multiplied terms that are in the denominator

$3(x-4)=2(x-2)$

Distribute

$3x-12=2(x+2)$

Distribute

$3x-12=2x+4$

Add 12 to both sides of the equation

$3x-12+12=2x+4+12$

Simplify

$3x=2x+16$

Subtract 2x from both sides of the equation

$3x=2x=2x+16-2x$

Simplify

$x=16$

The mean is 36

And, the standard deviation is 10

We take the sample of 16 individuals and the same would be randomly chosen

We need to find out that whether the given statement is true or false

So,

The given statement is true as the random variable means the average percent that could be consumed each day by a person

−5x−5y= −30 10x+3y= −3

dusya [7]

Answer:

x = -3, y = 9

Step-by-step explanation:

-5x - 5y = -30

x - y = 6

x = -y + 6

10x + 3y = -3

10(-y + 6) + 3y = -3 (plug in x from the previous equation)

60 - 10y + 3y = -3

60 - 7y = -3

-7y = -63

y = 9

x = -y + 6

x = -(9) + 6

x = -3
