Answer:

x=o and y= -6

Step-by-step explanation:

12-2x = - 2(y-x)

or,12-2x = -2y + 2x

or, 12 = - 2y + 4x

or, 12/2= 2x - y

or, 2x - y = 6

• 2x -6= y.....eqn_1

-2x=-2y+2x -12

or,4x +2y= -12

or,4x + 2(2x-6)= -12

or, 4x+4x-12=-12

or, 8x= 0

• x= o

putting the value of x in eqn...3

o=(y-0)+6

or, o= y + 6

•y = -6

A box contains 1414 large marbles and 1111 small marbles. Each marble is either green or white. 66 of the large marbles are gree
Luba_88 [7]

Answer:

0.9739

Step-by-step explanation:

We have 1111+1414=2525 marbles, and

44 small white matbles and

1414-66=1348 big white marbles.

So we have 44+1348=1392 white marbles.

The probability to choose small marbles is P(s)=1111/2525=0,44

The probability to choose white marbles is:

P(w)=1348/2525=0,5513.

The probability to choose small and white is:

P(s and w)=44/2525=0,0174

The probability to choose small or white is:

P(s or w)= P(s)+P(w)-P(s and w)=0,44+0,5513-0.0174=0,9739

Nora bought 100 Shares of a technology stock and 200 shares of a mutual fund for $3500. Her sister, Erin, bought 300 shares of t
viktelen [127]

Answer:Suppose the cost stock is x and the cost of fund is y.

Total cost of Nora's portfolio:

100x+200y=3800.....i

Total cost of Erin's portfolio

300x+50y=5350...ii

solving the simultaneous equation by elimination method we proceed as follows:

multiplying eqn  by 3 and subtracting ii we get:

550y=6050

thus

y=6050/550

y=11

next, multiply ii by 4 and subtracting i we get:

1100x=17600

x=16

thus the cost of Technology stock was $16 and the cost of mutual fund was $11
