How can one 1/4x − 3 = 1/2x + 8 be set up as a system of equations?

1 answer:

3 0

You can set y = to each side of the equation, then multiply by the denominator and put into standard form.

Left side:
.. y = 1/4x -3
.. 4y = x -12 . . . . multiply by 4
.. 4y -x = -12 . . . subtract x

Right side:
.. y = 1/2x +8
.. 2y = x +16 . . . multiply by 2
.. 2y -x = 16 . . . subtract x

These equations correspond to selection B.

What is the discount of a guitar with an original price of $95 and a discount of 15%.

maks197457 [2]

Answer:

$80.75 dollars

Step-by-step explanation:

Given the following question:
Initial price = $95
15% discount

In order to find the answer, we have to find 15% of 95.

$\frac{15\times95}{100} =15\times95=1425\div100=14.25$
$95-14.25=80.75$
$g=80.75$

The guitar (after a 15% discount) costs "$80.75 dollars."

Hope this helps.

Answer: The side length is 3 yards.

Step-by-step explanation:

To find the area of a square, you have to square one of it's side lengths since they all share the same length. Since we know the area, and we need to find the side length so we just need to find the square root of the area.

$\sqrt{9}$ = 3
