Determine whether the systems have one solution, no solution, or infinitely many solutions. 3x-2y=3; 6x-4y=1

Alik [6]

The equation has no solution.

<h3>How to solve the equation?</h3>

The equation given is illustrated as:

3x-2y=3 .... i

6x-4y=1 ..... ii

Multiply equation i by 6

Multiply equation ii by 3

18x - 12y = 18

18x - 12y = 3

Subtract the equations.

This will give 0. Therefore, the equations gas no solution.

saul85 [17]

Answer: Team A will choose one of 36 possible lineups.

Step-by-step explanation: Given that Team A and Team B are playing the game of tug-of-war.

Team A has 3 males and 3 females that decides to line up male, female, male, female, male, female.

We are to find the number of possible lineups that Team A can make.

According to the given information,

number of options for the first position = 3,

number of options for the second position = 3,

number of options for the third position = 2,

number of options for the fourth position = 2,

number of options for the fifth position = 1

and

number of options for the sixth position = 1.

Therefore, the number of possible lineups by Team A is

$n=3\times3\times2\times2\times1\times1=36.$

Thus, Team A will choose one of 36 possible lineups.

In Juan's coin bank there are nickels (n),

alukav5142 [94]

Answer:

The answer is 8 quarters, 16 nickles, and 32 dimes

Step-by-step explanation:

First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.)
Then we slowly start to solve: 10/4d + 10d + 25/4d = 600
10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d)
75d= 600 x 4
d=600 x 4/75 (same here put everything over 75)
d=32
So then n= 2 x 32/4 = 16
Then n would be equal to : 1/4d= 1/4 x 32 = 8
So your answer would be 8 quarters, 16 nickles, and 32 dimes.

Hope this helped :)
