14a - (2a +9)=2/3 (12a-18)

Dmitrij [34]

Answer: a=-0.75

Step-by-step explanation:

14a - (2a +9)=2/3 (12a-18)

14a - 2a -9=2/3 * 6(2a-3)

12a-9=2*6/3 (2a-3)

12a-9=2*2(2a-3)

12a-9=4(2a-3)

12a-9=8a-12

4a-9=-12

4a=-3

a=-3/4

a=-0.75

A company manufactures cell phones. In August, a random sample of 125 cell phones was inspected, and 3 phones were found to be d

german

Answer:

192

Step-by-step explanation:

To find how many phones are expected to be defective, we need to represent the values in a fraction.

$\dfrac{x}{8000}=\dfrac{3}{125}$

x = number of defective phones

Now we can solve this using algebra.

To get the value of x we need to multiply both sides by 8000 to leave x alone.

$x=\dfrac{3}{125}(8000)$

$x=0.024(8000)$

$x=192$

So around 192 cell phones are expected to be defective out of 8000 phones.

Find the value of x and y

tankabanditka [31]

Answer:

x = 3, y = 10.

Step-by-step explanation:

The 2 triangles are similar so the corresponding sides are in the same ratio.

x/6 = 4/8

x/6 = 1/2

x = 6/2 = 3.

y/5 = 8/4 = 2

y = 5*2 = 10,

Which equation represents a line which is parallel to the line x-8y=48 x−8y=48?

Daniel [21]

When the slopes of two lines are equal,they are parallel.
$x - 8y = 48 \\ - 8y = - 1x + 48 \\ y = \frac{1}{8}x + 6$
so the equation of the parallel line to this one is :
$y = \frac{1}{8} x$
hope this helps
