Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row
Answer:
42 Degrees
Step-by-step explanation:
Angle ABF is parallel to the angle DCF
Y-5=-1/2(X-2)
the simplified version of this equation (so you can plug into a calculator) is
Y=-1/2x+6
Answer:
66 oz
Step-by-step explanation:
Every 2 cups have 11 ounces of ground coffee. Two times six is 12, so 11 times 6 is 66.
Another explanation is-
2/12 = 11/x
12 times 11 is 132. Then divide that by two to get 66
It would be subtraction I think
