grandymaker [24]

Answer:

431 reserved tickets, 1356 general tickets

Step-by-step explanation:

4x + 3y = 5792

x + y = 1787

Start with these equations and guess numbers and eventually you'll be right


1000x + 787y =6361 WRONG

700x + 1087y = 6061 WRONG

500 x + 1287y = 5861, close but WRONG

430 x + 1357 y = 5791, very close but WRONG

431 x + 1356y = $5792, CORRECT

431 + 1356 = 1787 tickets sold

S is the centroid of triangle NQL. What is the length of NR?
svetoff [14.1K]
ANSWER

The length of NR is
36 \: \: units

EXPLANATION

The centroids divides the medians in the ratio
2:1
For instance

|NS|:|SR|=2:1

But

|NS| = 9n - 12

|SR|=3n

We substitute all these values in to the above relation to obtain,

(9n - 12):3n=2:1

This can be rewritten as

\frac{9n - 12}{3n} = \frac{2}{1}

We cross multiply to obtain,

1(9n - 12) = 2 \times 3n

This implies that,

9n - 12 = 6n

We group like terms to obtain,

9n - 6n = 12

This simplifies to give us,

3n = 12

n = 4

We can now determine each length as follows,

|NS| = 9(4 ) - 12

|NS| = 36- 12

|NS| = 24

|SR|=3 \times 4

|SR|=12

From the diagram,

|NR|=|NS|+|SR|

|NR|=24 + 12

|NR|=36 \: units
