Answer:

165

Step-by-step explanation:

Let o and b represent the numbers of orchestra and balcony tickets bought, respectively.

o + b ≥ 250 . . . . at least 250 tickets will be bought

o = b - 80 . . . . . there will be 80 fewer orchestra than balcony bought

Substituting for o, we have ...

(b -80) +b ≥ 250

2b ≥ 330 . . . . . . . add 80

b ≥ 165 . . . . . . . . .divide by 2

The least number of balcony tickets the club could buy is 165.

Answer:

$x = 5$

Step-by-step explanation:

$4x = 1x + 15 \\ 4x - 1x = 15 \\ 3x = 15 \\ \frac{3x}{3} = \frac{15}{3} \\ x = 5$

For each x and n, find the multiplicative inverse mod n of x. Your answer should be an integer s in the range 0 through n - 1. C

Use the Euclidean algorithm to express 1 as a linear combination of $x$ and $n$ .

a. $52^{-1}\equiv40\pmod{77}$ because

77 = 1*52 + 25

52 = 2*25 + 2

25 = 12*2 + 1

so we can write

1 = 25 - 12*2 = 25*25 - 12*52 = (77 - 52)(77 - 52) - 12*52 = 77^2 - 2*52*77 + 52^2 - 12*52

Taken modulo 77 leaves us with

$1\equiv52\cdot52-12\cdot52\equiv40\cdot52\pmod{77}\implies52^{-1}\equiv40\pmod{77}$

b. First, $77\equiv25\pmod{52}$ , so really we're looking for the inverse of 25 mod 52. We've basically done the work in part (a) already:

1 = 25*25 - 12*52

Taken modulo 52, we're left with

$1\equiv25\cdot25\pmod{52}\implies25^{-1}\equiv25\pmod{52}$

c. The EA gives

71 = 1*53 + 18

53 = 2*18 + 17

18 = 1*17 + 1

so we get

1 = 18 - 17 = 3*18 - 53 = 3*71 - 4*53

so that taken module 71, we find

$1\equiv(-4)\cdot53\pmod{71}\implies53^{-1}\equiv-4\equiv67\pmod{71}$

d. Same process as with (b). First we have $71\equiv18\pmod{53}$ , and we've already shown that

1 = 3*18 - 53

which means, taken modulo 53, that

$1\equiv3\cdot18\pmod{53}\implies71^{-1}\equiv18^{-1}\equiv3\pmod{53}$
