Solve by elimination 2x-3y=2 -2x-y=-26

Kisachek [45]

Answer:

x= 10, y= 6

Step-by-step explanation:

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

-2x -y= -26 -----(2)

(1) +(2):

2x -3y -2x -y= 2 -26

-4y= -24

y= -24 ÷(-4)

y= 6

Substitute y= 6 into (1):

2x -3(6)= 2

2x -18= 2

2x= 18 +2

2x= 20

Divide both sides by 2:

x= 20 ÷2

x= 10

In a 56 pound mixture of sand and gravel, 14 pound is gravel. How much gravel is there in a 1-pound mixture? 445 lb 313 l

Ivenika [448]

Divide the amount of gravel in the 5/6 pound mixture:

1/4 / 5/6 = 1/4 * 6/5 = 6/20 = 3/10 pounds

Let B1W2 denote the outcome that the first ball drawn is B1 and the second ball drawn is W2. Because the first ball is replaced

Sati [7]

Answer:

$\{B_1B_1, B_1B_2, B_1W_1, B_1W_2, B_1W_3, \\B_2B_1, B_2B_2, B_2W_1, B_2W_2, B_2W_3, \\$

$W_1B_1,W_1B_2, W_1W_1, W_1W_2, W_1W_3, \\W_2B_1, W_2B_2, W_2W_1,W_2W_2, W_2W_3, \\W_3B_1, W_3B_2, W_3W_1, W_3W_2, W_3W_3\}$

Step-by-step explanation:

$\text{If an urn contains two blue balls} (denoted \:B_1 \:and \:B_2) \text{and three white balls}$ , $(denoted \:W_1, W_2, \:and\: W_3)$

If One ball is drawn, its color is recorded, and it is replaced in the urn. Then another ball is drawn and its color is recorded.

The 25 Possible outcomes of this experiment are listed below:

$\{B_1B_1, B_1B_2, B_1W_1, B_1W_2, B_1W_3, \\B_2B_1, B_2B_2, B_2W_1, B_2W_2, B_2W_3, \\$

$W_1B_1,W_1B_2, W_1W_1, W_1W_2, W_1W_3, \\W_2B_1, W_2B_2, W_2W_1,W_2W_2, W_2W_3, \\W_3B_1, W_3B_2, W_3W_1, W_3W_2, W_3W_3\}$
