Answer:

x = 9

Step-by-step explanation:

The line splits the sides of the triangle in proportion (the ratios of the pieces is the same for both sides).

Setup:

\frac{8}{3x+1}=\frac{2}{x-2}

"Cross multiply."

2(3x+1)=8(x-2)\\6x+2=8x-16\\18=2x\\9=x

Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
inn [45]

Answer:

Númer total de ladrillos= 256

Step-by-step explanation:

<u>Dada la siguiente información:</u>

Total de pisos= 16

Total de ladrillos por piso= 16

<u>Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:</u>

Número total de ladrillos= total de ladrillos^2

Número total de ladrillos= 16^2

Númer total de ladrillos= 256

En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

For 4 days, you give a patient 1 1/2 oz of medication 5 times per day. How much medication did you give the patient over the 4 d
Lelu [443]
You multiply 1 1/2 by 5 (because you give it to them 5 times a day) and you get 7 1/2 then you have to multiply that by 4 (because you’re calculating how much over 4 days) and you get 30oz .

HOTS... Just solve this questions <br>​
AfilCa [17]

Answer:

Step-by-step explanation:

8.  B is the midpoint of AD

A (x,y)

D( -1,3)      B (  (x-1)/2, (y+3)/2)  and B ( 1,1)

then (x-1)/2=1, x-1=2   ( +1)  ,  x= 2+1,  x=3

        (y+3)/2=1, y+3=2 ( -3)     y=2-3,  y= -1

then A (3, -1)

9. (-8,3)

    (s,3)      the midpoint  (0,u)

then    (s-8)/2=0,   s=8

           (3+3)/2=u,   u=6/2,   u= 3

10.  a=1   ( the y coordinate is  the same as the midpoint

  A(3,1)

   B(x,y)    the midpoint (5,1)

   (3+x)/2=5,   3+x=10 ,   x=10-3,  x=7

    (y+1)/2=1,  y+1=2,y=2-1,     y=1

B(7,1)
