Solve the equation <br> 3x-y=28<br> 3x+y=14
Elis [28]

Answer:

  (x, y) = (7, -7)

Step-by-step explanation:

You can eliminate y by adding the two equations:

  (3x -y) +(3x +y) = (28) +(14)

  6x = 42 . . . . simplify

  x = 7 . . . . . . divide by 6

You can eliminate x by subtracting the two equations:

  (3x +y) -(3x -y) = (14) -(28)

  2y = -14 . . . . simplify

  y = -7 . . . . . . divide by 2

The solution is (x, y) = (7, -7).

Team D used a recipe that consists of 20 cups of sand, 2 cups of flour, and 3 cups of water. How does the percent of sand in Tea
spayn [35]

Answer:

80%

Step-by-step explanation:

Given:

Team D used a recipe that consists of 20 cups of sand, 2 cups of flour, and 3 cups of water.

Question asked:

How does the percent of sand in Team D's recipe compare to that of the other teams ?

Solution:

Team D used a recipe that consists of sand = 20 cups

Team D used a recipe that consists of  flour =  2 cups

Team D used a recipe that consists of  water = 3 cups

Total number of cups together = 20 + 2+ 3 =25 cups

Now we will have to find percent of cups of sand out of the total number of cups.

By using formula of percentage,

Percent = \frac{Value}{Total \ value}\times100

             =\frac{20}{25} \times100\\=\frac{2000}{25} =80\%

Therefore, 80% of sand in Team D's recipe compare to that of the other teams.

If you were to roll the dice one time what is the probability it will NOT land on a 2?
Nikitich [7]

Answer:

5 / 6

Step-by-step explanation:

Given that:

Probability that a dice rolled once will not land on 2

Probability = required outcome / Total possible outcomes

Total possible outcomes = (1, 2, 3, 4, 5, 6)

Required outcome = 2

P(not land on 2) = 1 - p(land on 2)

P(land on 2) = 1/6

P(not land on 2) = 1 - 1/6

P(not land on 2) = 5/6
