Answer:

30%

Step-by-step explanation:

The stock gained by 6. So 6/20. Next we want to turn the denominator (20) into 100 through multiplication. 20 * 5 = 100. Multiply the bottom AND top by 5 which equals 30/100. Thus the percentage is 30%

Answer:

30%.

Step-by-step explanation:

Divide the increase by the original price x 100%.

26-20/20, then do 6/20. 6/20 is also equivalent to 30/100 so the percentage would also be 30%.

Hope that helps. x

Kellen bought new fish for her home aquarium. She bought 4 turquoise guppies and 3 sunburst tetra GLO fish and spent a total of
FromTheMoon [43]

Answer: A single turquoise guppy costs $3.69

Step-by-step explanation:

Let us use "x" to represent the amount a single turquoise is sold and use "y" to represent that of the Glo fish.

Since Kellen bought 4 guppies and 3 glo fishes for $41.73:

4x + 3y = 41.73 --------eqn 1

Similarly, Danielle purchased 3 guppies and 5 Glo fish for $56.02:

Therefore 3x + 5y = $56.02 -----eqn2

The 2 equations are;

4x + 3y = 41.73 (eqn 1)

3x + 5y = 56.02 (eqn 2)

We then solve the simultaneous equations using substitution method:

From eqn 1,

4x + 3y = 41.73

4x = 41.73 - 3y

x = (41.73 - 3y)/4

Substitute x for (41.73 - 3y)/4 in eqn2.

3[(41.73 - 3y)/4 + 5y = 56.02

11y + 125.19 = 224.08

11y =98.89

y = 98.89/11

y = $8.99

So, 1 Glo fish costs $8.99

Then, substitute "y" for 8.99 in equation 1

4x + (3×8.99) = 41.73

4x + 26.97 = 41.73

4x = 41.73 - 26.97

4x = 14.76

x = 14.76/4

x = $3.69

Therefore 1 turquoise guppy costs $3.69

First, let's find the value of X:

2x + 4x + 3x = 81

9x = 81

x = 9

Then, multiply it by the biggest side which is 4:

9 x 4 = 36

Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x −
zloy xaker [14]

Answer:

  • Only one solution
  • (x, y) = (-0.8, -3.6)

Step-by-step explanation:

You know there is only one solution because the ratio of x- and y-coefficients is different in the two equations. That means the lines will have different slopes, so must intersect in exactly one point.

__

The y-coefficients are opposites, so you can eliminate the y-variable by adding the equations:

  (2x -y) + (3x +y) = (2) + (-6)

  5x = -4

  x = -4/5 = -0.8

Substituting this into the second equation, we have ...

  3(-0.8) +y = -6

  y = -3.6 . . . . . . . add 2.4 to both sides

The solution is (x, y) = (-0.8, -3.6).

__

You can also find the solution by graphing (or using a graphing calculator).
