Well.
3+2 = 5
And 2x = 6 is a simple equation.

Our main goal is to isolate the x (get the x to be alone)
Our first step is to divide both sides by 2
2x = 6
—- —-
2 2

Both 2’s on the left side cancel out. (Disappear)
And we solve on the right side.
6/2 = 3
Answer: x = 3


GOOD LUCK!

Tickets for a minor league baseball game for an adult and two children cost a total of $21 the adult ticket is three dollars mor
oksian1 [2.3K]

Answer:the cost of one child's ticket is $6

the cost of one adult ticket is $9

Step-by-step explanation:

Let x represent the cost of one child's ticket

Let y represent the cost of one adult ticket.

Tickets for a minor league baseball game for an adult and two children cost a total of $21. This means that

2x + y = 21 - - - - - - - - - - 1

The adult ticket is three dollars more than a child's ticket. This means that

y = x + 3

Substituting y = x + 3 into equation 1, it becomes

2x + x + 3 = 21

3x + 3 = 21

3x = 21 - 3 = 18

x = 18/3 = 6

y = x + 3 = 6 + 3

y = 9

Select the correct answer from each drop-down menu.
Aleks [24]

Answer:

6x^2+5x-6=(3x-2)(2x+3)

Step-by-step explanation:

<u>Given expression</u>:

6x^2+5x-6

To factor a quadratic in the form ax^2+bx+c, first find two numbers that multiply to ac and sum to b:

\implies ac=6 \cdot -6=-36

\implies b=5

Two numbers that multiply to -36 and sum to 5 are: 9 and -4

Rewrite b as the sum of these two numbers:

\implies 6x^2+9x-4x-6

Factorize the first two terms and the last two terms separately:

\implies 3x(2x+3)-2(2x+3)

Factor out the common term (2x + 3):

\implies (3x-2)(2x+3)

Therefore:

6x^2+5x-6=(3x-2)(2x+3)

What is the perimeter of triangle ABC?
kkurt [141]

Option B:

The perimeter of ΔABC is 28 units.

Solution:

AD = 5, DC = 6 and AB = 8

AD and AE are tangents to a circle from an external point A.

BE and BF are tangents to a circle from an external point B.

CD and CF are tangents to a circle from an external point C.

<em>Tangents drawn from an external point to a circle are equal in length.</em>

⇒ AD = AE, BE = BF and CD = CF

AE = 5

AE + BE = AB

5 + BE = 8

Subtract 5 from both sides.

BE = 3

BE = BF

⇒ BF = 3

CD = CF

⇒ CF = 6

Perimeter of the polygon = AE + BE + BF + CF + CD + AD

                                         = 5 + 3 + 3 + 6 + 6 + 5

                                         = 28

The perimeter of ΔABC is 28 units.

Option B is the correct answer.
