Answer:

Yes. It works in the equation.

Step-by-step explanation:

To see if (4,16) is on the line, substitute (4,16) into the equation.

y = 4x

16 = 4*4

16 = 16

It satisfies the equation and makes it a solution.

|x-5|=3 Whats x? please help?

finlep [7]

Answer:

x = 8 or x = 2

Step-by-step explanation:

We know x - 5 = 3 or x - 5 = -3.

Possibility 1:

Step 1: Add 5 to both sides.

$x-5+5=3+5$
$x=8$

Possibility 2:

Step 1: Add 5 to both sides.

$x-5+5=-3+5$
$x=2$

Step 2: Check if both solutions apply to original equation.

$|8-5|=3$
$|3|=3$
$3=3$
$|2-5|=3$
$|-3|=3$
$3=3$

A sells to b an item at 15% profit. B sells the same item to c at 20% profit. If c pays $1656 for it. What is the price at which

andrew11 [14]

Answer:

The price at which A bought the item is $1200.

Step-by-step explanation:

Suppose, the price at which A bought the item is $x$ dollar.

A sells the item to B at 15% profit. That means, the selling price to B $= x+(0.15*x)=1.15x$ dollar.

B sells the same item to C at 20% profit. That means, the selling price to C $= 1.15x+(1.15x*0.20)=1.38x$ dollar.

Given that, C pays $1656 for the item. So, the equation will be.......

$1.38x=1656\\ \\ x=\frac{1656}{1.38}=1200$

So, the price at which A bought the item is $1200.
