Draw out a number line with the values 0, 5, 10, 15, 20, 25, 30, etc (basically multiples of 5)

Then plot a point at 25

-----------------

Or you can draw out a number line with the multiples of 10, so with the values 0, 10, 20, 30, ...

Then plot a point at the exact midway point between 20 and 30 to represent the value 25

El precio de un ordenador portátil ha aumentado un 25% y posteriormente fue rebajado un cierto porcentaje.Calcule que porcentaje
ZanzabumX [31]

Answer:

Se requiere un 20 por ciento de descuento.

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in the same language)

Sea p_{o} el precio original del computador portatil, el nuevo precio es:

p_{1} =\left(\frac{100\,\% + 25\,\%}{100\,\%} \right)\cdot p_{o}

p_{1} = 1.25\cdot p_{o}

Si p_{2} = p_{o}, entonces el porcentaje requerido para recuperar el precio original es:

r = \left(1-\frac{p_{2}}{p_{1}} \right)\times 100\,\%

r = \left(1-\frac{p_{o}}{1.25\cdot p_{o}} \right)\times 100\,\%

r = \left(1-\frac{1}{1.25} \right)\times 100\,\%

r = 20\,\%

Se requiere un 20 por ciento de descuento.

Figure ABCD is a trapezoid. Find
Rudiy27

Answer:

x = 3

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

\frac{1}{2} (3x + 3 + 4x + 2) = 13

\frac{1}{2} (7x + 5) = 13 ( multiply both sides by 2 )

7x + 5 = 26 ( subtract 5 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3

WILL AWARD BRAINIEST!! Question is in the attached image.
professor190 [17]

Answer:

Look down at explanation

Step-by-step explanation:

First off if it is true in inches you could use a ruler to measure the bottom it works if you are desperate a lot of the time. Also the bottom of the trapezoid is 6 meters. If you didn't know the perimeter you could split the trapezoid into a rectangle and a triangle. You just have to take off the irrelevant sides when you put it together. So you take the 2 meters from the top of the trapezoid and then the bottom of the triangle is 4, so just split up the trapezoid and find the perimeter of the triangle and rectangle.
