Let x = number of adults tickets sold
then, 1750 - x = number of children tickets sold
We know that the cost for adult tickets is $5 and and children is above calculated so sum total tickets sold cost is $7100.
($5)(x) + ($2)(1750-x) = $7100
5x - 2x + 3500 = 7100
3x = 3600
x = 1200
You can't, the K cancels itself out. There is no solution to this
Volume is l × w × h
l = 21 in
h = 5 in
w = ?
volume = 1575 in
21 × 5 × w = 1575
105 × w = 1575
w = 1575 ÷ 105
w = 15 inches
Answer:
The answer is: 13 minutes
Step-by-step explanation:
First Let us form equations with the statements in the two scenario
Let the time in which the bell rings be 'x'
1. If Andrew walks (50 meters/minute), he arrives 3 minutes after the bell rings. Therefore the time of arrival at this speed = (3 + x) minutes
2. If Andrew runs (80 meters/minute), he arrives 3 minutes before the bell rings. Therefore the time taken to travel the distance = (x - 3) minutes

In both cases, the same distance is travelled, therefore, equation (1) = equation (2)

Next, collecting like terms:

dividing both sides by 3:
x = 390÷30 = 13
∴ x = 13 minutes
