given equation,

3x+2y=1 ------------>(1)

x=5y+6 ------------>(2)

from (1) and(2),

3(5y+6)+2y=1

or, 15y+18+2y=1

or, 17y=1-18

or, 17y= -17

or, y= -17/17

:. y= -1 and x=5y+6=5×(-1)+6= -5+6=1

::: x= 1

:::y= -1 ans.

Hay 12 canicas en una bolsa y 6
Genrish500 [490]

Answer:

50%.

Step-by-step explanation:

Dado que hay 12 canicas en una bolsa y 6 de ellas son verdes, para determinar la probabilidad de que si se elige una canica al azar, esta sea verde, se debe realizar el siguiente cálculo:

6 / 12 = X

0.5 = X

0.5 = 50/100

50/100 = 50%

Así, hay un 50% de probabilidades de que, eligiendo una canica al azar dentro de la bolsa, la canica elegida sea verde.

What is (1.2 x 10^-2) x (3 x 10^5)
liraira [26]

Answer:

B. 3.6 x 10^3

Step-by-step explanation:

(1.2 x 10^-2) x (3 x 10^5)

When we multiply terms with powers , we multiply the factors out front and add the exponents

a * 10^b  * c* 10^d = ac * 10^(b+d)

(1.2 x 10^-2) x (3 x 10^5)   = (1.2* 3) * 10^(-2+5)

                                         = 3.6 * 10 ^3

You reflect triangle PQR, with coordinates P(-4, -4), Q(-1, -3), and R(-3, -1), across the x-axis, across the y-axis, and across
notka56 [123]

Answer:

  P'( 4, -4)

Step-by-step explanation:

The double reflection across the x-axis does nothing, so the net effect is a single reflection across the y-axis. That effect is to negate the x-coordinate:

  reflection across y-axis: (x, y) ⇒ (-x, y)

  Then P(-4, -4) ⇒ P'(4, -4)
