Answer:
a) yes, as the number of seats (2352) is larger than the total audience (1912)
b) 440 empty seats
Step-by-step explanation:
a) total number of seats = number of rows x number of seats in each row
total number of seats = 49 x 48
total number of seats = 2352 seats
total audience = 1854 students + 58 teachers
total audience = 1912 people
b) empty seats = total number of seats - total audience
empty seats = 2352 - 1912
empty seats = 440
Answer:
The porch is 17 ft by 17 ft
Step-by-step explanation:
The perimeter of a square is
P = 4s where s is the side length
P = 4( 3x+2)
P = 12x+8
We know P = 14x-2
14x-2 = 12x+8
Subtract 12x from each side
14x-2 -12x = 12x+8-12x
2x -2 = 8
Add 2 to each side
2x-2 +2 = 8+2
2x= 10
Divide by 2
2x/2 = 10/2
x = 5
The side is 3x+2
3*5+2
15+2
17

Assume E represents the cost of an egg and T represents the cost of one piece of toast.
We can construct two equations :
2E + T = $3.00 - - - - - (a)
E + T = $1.80 - - - - - (b)
Subtract equation b from a:
E = $1.20 (The price of one egg)
To find out the price of one piece of toast, replace the price of one egg in equation b:
T = $1.80 - $1.20 = $0.60 (The price of one piece of toast)
