Answer:

x = 31

Step-by-step explanation:

The perimeter is the sum of the equal-length sides:

63 = (x -10) +(x -10) +(x -10)

63 = 3x -30 . . . . . . . . collect terms

21 = x -10 . . . . . . . . . . divide by 3

31 = x . . . . . . . . . . . . . add 10

Answer:

$given \: that \: the \: cost \: of \: orchestra \: is \: three \: times \: of \: balcony \: ticket \\ let \: the \:cost \: of \: balcony \: \: ticket \: be \:x \\ so \: the \: cost \: of \: orchestra \: ticket \: sold \: be \: 3x \\ the \: total \: income = 3640 \\ \\ so \: the \: equation \: formed \: = > 148(3x)+ 76(x) = 3640 \\ = > 444x + 76x = 3640 \\ = > 520x = 3640 \\ = > x = \frac{3640}{520} \\ = > x = 7$

$so \: orchestra \: ticket \: = 444x = 444 \times = 3108 \\ and \: balcony \: ticket \: = 76x = 76 \times 7 = 532$

FOR PROOF = 3108+532 = 3640 total income

The segments shown below could form a triangle?

Leni [432]

Answer:

<em>Option B; False</em>

Step-by-step explanation:

Consider a Triangle Inequality to prove that these segments could form a triangle;

$| a - b | < c < a + b,\\| c - a | < b < a + c,\\| c - b | < a < b + c, Considering - a - segment AC ( 8 units ) - b - BC ( 7 units ), - c - BC ( 15 units )\\\\| 8 - 7 | < 15 < 8 + 7,\\1 < 15 < 15, Now 15 is not < 15, it is =, thus ;\\Solution ; False$
