Simplify the expression 2p + 3/4p + 6 - p - 3 1/2

lozanna [386]

Answer:

The simplified expression is "7p/4 + 2 1/2" or "1.75p + 2.5".

Step-by-step explanation:

2p + 3/4p + 6 - p - 3 1/2
=> (2p - p + 3/4p) + (6 - 3.5)
=> 1.75p + 2.5

Hence, the simplified expression is "7p/4 + 2 1/2" or "1.75p + 2.5". Any of these would work.

Solve for x: 5/x^2-4+2/x=2/x-2

IRINA_888 [86]

$\dfrac{5}{x^2 - 4} + \dfrac{2}{x} = \dfrac{2}{x - 2}$

$\dfrac{5}{(x + 2)(x - 2)} + \dfrac{2}{x} = \dfrac{2}{x - 2}$

$\dfrac{5}{(x + 2)(x - 2)} \times x(x + 2)(x - 2) + \dfrac{2}{x} \times x(x + 2)(x - 2) = \dfrac{2}{x - 2} \times x(x + 2)(x - 2)$

$5x + 2(x + 2)(x - 2) = 2x(x + 2)$

$5x + 2(x^2 - 4) = 2x^2 + 4x$

$5x + 2x^2 - 8 = 2x^2 + 4x$

$5x - 8 = 4x$

$x - 8 = 0$

$x = 8$

Now we look at the common denominator.

It is x(x + 2)(x - 2).

x cannot be zero, -2 or 2 because that would cause a zero in the denominator.

Since we get x = 8, and x = 8 does not have to be excluded from the domain, the answer is x = 8.

Answer: x = 8

7% of 500 is 35 so add 35 to 500 and you get 535.
