Answer: (5, 12)

Step-by-step explanation:

Just graph the linear equations and find where they intersect.

Algebraically, you can set them equal to each other

-3x-3=2x+2

-x-3=2

-x=5

x=5

Plug x=5 to any equation

y=2(5)+2

y=12

12x15y=4140; x+y= ? <br> solve.
Semenov [28]

Answer: The number of $12 tickets and $15 sold are 120 and 180 respectively.

Step-by-step explanation:

The given equation is:

12x + 15y = 4140             .....(1)

Where,

x stands for $12 tickets and y stands for $15 tickets

According to the question:

x + y = 300           ....(2)

Now solving equation 1 and 2.

From equation 2:

x = 300 - y

Now putting this expression in equation 1.

12x + 15y = 4140

12(300 - y) + 15y = 4140

3600 - 12y + 15y = 4140

3600 + 3y = 4140

3y = 4140 - 3600

3y = 540

y = 180

And,

x = 300 - y = 300 - 180 = 120

The number of $12 tickets sold = x = 120

The number of $15 tickets sold = y = 180

Thus, the number of $12 tickets and $15 sold are 120 and 180 respectively.

If the perimeter of an equilateral triangle is 30 ft, what is the area?
Sergio039 [100]
Divide the perimeter by 3 to find the side length.
Since the formula for the are of a triangle is
1/2 * b * h the height must be found.
If a perpendicular line is drawn from the apex of the triangle, a right triangle is formed with a base of 5 and a hypotenuse of 10. Also since it originally was equilateral the base angle is 60 degrees. The rules for finding lengths of sides of equal. Triangles is long leg = sqrt3 * short leg
the height is the long leg so the height is 5sqrt3.
A=(1/2)(10)(5sqrt3)= 25sqrt3

Jada created the two-way table below to describe the performance of her basketball team this season.
kykrilka [37]

Answer:

The correct option is 1, 4 and 6.

Step-by-step explanation:

The given two-way table is

                          WIN          LOSS          TOTAL

HOME GAMES     6               10               16

AWAY GAMES      3                8                11

TOTAL                   9              18               27

Total number of home games won by team is 6 and total number of away games won by team is 3. It means the team is twice as likely to win a home game as they are an away game.

The correct option is 1.

Total number of home games = 16.

Home game won by team is

\frac{6}{16}=\frac{3}{8}

Option 2 is incorrect.

Total games = 27

Total games won by the team = 9

Total part of games won by team is

\frac{9}{27}=\frac{1}{3}

Option 3 is incorrect.

The team played a total of 27 games.

Option 4 is correct.

The team won a total of 9 games.

Option 5 is incorrect.

Total home games loose by team = 10

Total away games loose by team = 8

The team lost more home games than away games.

Option 6 is correct.

Therefore the correct option is 1, 4 and 6.
