Determine single-digit values of M for which the products M*5 end in 5.  They are M={1,3,5,7, ...}.  Note, for example, that 7*M5 ends in 5, the last digit of 385.  Even values of M (as in {2,4,6,8,...} do not have products that end in 5, and thus must be eliminated.

Next, note that if N=5, then M*5 becomes 75, and that 75 multiplied by 5 comes out to 385, which is the desired product.  

Noting that L times N*5 (that is, L times 55) = 385, L has to be the same as M, and is in fact 7.  Then L times N*5 comes out to 385.

In summary:  N=5, M=7 and L=7.

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

<h3>\frac{a + bc}{wd + f}  = g</h3>

<u>First of all cross multiply</u>

That's

g( wd + f ) = a + bc

<u>Multiply the terms at the left side of the equation</u>

We have

gwd + fg = a + bc

<u>Send fg to the right side of the equation</u>

That's

gwd = a + bc - fg

<u>Divide both sides by dg to make W stand alone</u>

<h3>\frac{gwd}{dg}  =  \frac{a + bc - fg}{dg}</h3>

We have the final answer as

<h2 /><h2>w =  \frac{a + bc - fg}{dg}</h2>

Hope this helps you

Ecuación 2:<br> 10x + 20y = 8000<br> ayudaaa
Elenna [48]

Answer:

y = 300

x = 200

Step-by-step explanation:

Esta pregunta parece incompleta, parece que acá tenemos un sistema de ecuaciones:

x + y = 500

10*x + 20*y = 8000

Estas ecuaciones tienen que resolverse en conjunto, y de acá sacaremos un par de puntos (x, y) que son solución para ambas ecuaciones.

El primer paso para resolver esto es aislar una variable en una de las ecuaciones, en este caso podemos aislar x en la primera ecuación y así obtener:

x = 500 - y.

Ahora podemos reemplazar eso en la segunda ecuación y obtener:

10*(500 - y) + 20*y = 8000.

Ahora resolvemos esto para y.

5000 - 10*y + 20*y = 8000

10*y = 8000 - 5000 = 3000

y = 3000/10 = 300.

Y sabíamos que:

x = 500 - y = 500 - 300 = 200

Entonces la solución es:

y = 300

x = 200
