If a divides c,

then 'a' is a factor of 'c'.

Also,

If 'b' divides c,

then 'b' is also a factor of 'c'

therefore,

'a' and 'b' are factors of 'c'

Hence, a and b divides 'c'

so, c = a*b

and ab will also divide c.

Hence, proved.

Find the slope of the line passing through the points (5, 7) and (5, -9)​
Fantom [35]

Answer:

undefined

Step-by-step explanation:

To find the slope, we can use the slope formula

m = (y2-y1)/(x2-x1)

   = (-9-7)/(5-5)

Three times the quantity five less than x, divided by the product of six and x
Elden [556K]

Answer:

\frac{3(x-5)}{6x}

Step-by-step explanation:

we know that

The phrase "Three times the quantity five less than x" means 3 multiplied by the difference of x minus 5

3(x-5)

The phrase "the product of six and x" means the number 6 multiplied by x

6x

therefore

The phrase" Three times the quantity five less than x, divided by the product of six and x" is equal to the quotient of 3(x-5) and 6x

\frac{3(x-5)}{6x}

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.
