Answer: x =47

Step-by-step explanation:

Let`s find <em>1:</em>

<em>y= 1 angle</em>

<em></em>

In a triangle the sum of the angles is 180 º, so you sum

66+21+y = 180

y= 180 - 66 - 21

y= 180-87

y= 93

<em>Let`s find x:</em>

the angle that is not written in the triangle where x is, is opposite by vertex to angle 1 or y, that is, they have the same value, so:

x + 40 + 93 = 180

x = 180 - 133

x = 47

For the last basketball game, 381 tickets were sold. Adult tickets sold for $7, and student tickets sold for $3. How many adult
vovikov84 [41]

Answer: 96 adult tickets were sold.

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of students tickets that were sold.

For the last basketball game, 381 tickets were sold. This means that

x + y = 381

Adult tickets sold for $7, and student tickets sold for $3. If the ticket sales totaled 1,527, it means that

7x + 3y = 1527 - - - - - - - - - - - -1

Substituting x = 381 - y into equation 1, it becomes

7(381 - y) + 3y = 1527

2667 - 7y + 3y = 1527

- 7y + 3y = 1527 - 2667

- 4y = - 1140

y = - 1140/- 4

y = 285

x = 381 - y = 381 - 285

x = 96

Write a scenario that could be represented by this equation: 3/4x = 12
Aneli [31]

Answer:

x=1 or x=16

Step-by-step explanation:

3/4x = 12      or        0.75x = 12

3/4x/3/4 = 12/3/4     or     0.75x/0.75 = 12/0.75

x=12/1 / 3/4

x= 4/4

x = 1                           or       x = 16

Write an expression for the area of this sweetuare
nata0808 [166]
Length = x + y

Area of a square = Length x Length

The expression can be :

1)  Area of the square = (x + y)(x + y) 

2) Area of the square = (x + y)²

3) Area of the square = x² + 2xy + y²

If the circumference of a circle measures 3/2TT cm, what is the area of the circle in terms of TT?
diamong [38]

Answer:

A = pi 9/16  cm^2

Step-by-step explanation:

The circumference is 3/2 pi

The circumference is given by

C = 2 * pi *r

3/2 pi = 2 * pi *r

Divide each side by 2 *pi

3/2 pi / 2 pi  = 2 pi r /2pi

3/4 cm = r

Now we can find the area

A = pi r^2

A = pi ( 3/4) ^2

A = pi 9/16  cm^2
