This is Confusing my friend...j=1. Hope I helped

Step-by-step explanation:

Rewrite the equation

Cancel out the common factor

Numerators MUST be equal sinse the expression on each side of the equation has the same denominator

−2x−(−5−4x)=−5(2x−7)

hoa [83]

Answer:

x = 2.5

Step-by-step explanation:

- 2x - ( - 5 - 4x ) = - 5 ( 2x - 7 )

- 2x + 5 + 4x = - 10x + 35

- 2x + 4x + 10x = 35 - 5

12x = 30

x =  $\frac{5}{2}$  = 2.5

Check the answer:

L.H.S. = - 2(2.5) - [ - 5 - 4(2.5) ] = 10

R.H.S. = - 5 [ 2(2.5) - 7 ] = 10

Answer:

The t distribution is used, because we have the standard deviation for the sample.

Step-by-step explanation:

When to use the z or the t distribution?

When we have the standard deviation for the population, we use the z distribution.

When we have the standard deviation for the sample, we use the t distribution.

In this question:

We have the standard deviation for the sample, which means that the t distribution is used.

What value of x is in the solution set of 3(x – 4) > 5x + 2?

bonufazy [111]

We have to simplify and get the value of x from this inequality given:

Given inequality,

$3(x - 4) > 5x + 2$

Now let's simplify by using distributive property,

$3x - 12 > 5x + 2$

We need to find x, so let's isolate x to the letter side of the inequality for calculation at ease.

$3x - 12 - 5x - 2 > 0$

$- 2x - 14 > 0$

Now, dividing -2 from both sides.

Note : As we are dividing a negative number from both sides, the sign of the inequality will be reversed.

$\dfrac{ - 2x - 14}{ - 2} > \dfrac{0}{ - 2}$

$x + 7 < 0$

Now subtracting -7 from both sides,

$x + 7 - 7 < 0 - 7$

$x < - 7$

Or, Interval of the equal $(- \infin, -7 ]$
