To answer this question, you need to multiply the number inside the bracket first. Then you can move the number to the right side of the equal sign and keep the x on the left side of the equal sign. The step would be like this
2(x – 5) - 6x= -22(2x - 10) - 6x = -222x - 6x = -22 +10-4x= -12x= -12/-4x=3
Hope this helps!!!

An assembly line inspector inspected 340 machine parts. 323 of the parts passed inspection. What percent of the machine parts di

tester [92]

Answer:

5% did not pass inspection

Step-by-step explanation:

Given

$Inspected= 340$

$Passed = 323$

Required

Determine the percentage of parts that didn't pass inspection.

First, we need to calculate the number of those that didn't pass inspection.

$Failed = Inspected - Passed$

$Failed = 340 - 323$

$Failed = 17$

Next, we calculate the percentage as follows:

$\% = \frac{Failed}{Inspected} * 100\%$

The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%

So:

$\% = \frac{17}{340} * 100\%$

$\% = \frac{17 * 100\%}{340}$

$\% = \frac{1700\%}{340}$

$\% = 5\%$

<em>5% did not pass inspection</em>

Find the value of x explain how you got your answer

aliya0001 [1]

Answer:

step 1: x+50+4x=90

the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.

step 2: x+50+4x=90

x+4x=50

5x=50

x=10

then you solve the equation, x is 10

-(5n-9)+3n=-2(5n-20)<br> what is n?

11Alexandr11 [23.1K]

Answer:

$n=3.875$

Step-by-step explanation:

First, we can expand the brackets:

$-(5n-9)+3n=-2(5n-20)$ (given)

$-5n+9+3n=-10n+40$

$-2n+9=-10n+40$ (combine like-terms)

$8n=31$

$n=3.875$

Hope this helps :)
