Let x= number rows
Then x + 5 = number of seats per row
x(x+5) = 126
X^2 + 5x = 126
x^2 + 5x -126 = 0; now factor or use quadratic:
(x+14)(x-9) = 0; so the answers are either -14, or 9, and since -14 is not possible in this case because you can't have a negative number of rows, the answer is 9 rows.
Check work: number of rows = 9, number of seats per row = 9+ 5= 14, and 9 x 14 = 126
The digit in the ten thousands place is printed slightly to the left
of the one in the thousands place.
If they are the same digit, then the value of the one on the left is
ten times the value of the one on the right.
Answer:
thr answers are A and D of the question
Answer and Step-by-step explanation:
First, find the total amount of marbles.
5 + 4 + 3 = 12
There are 12 marbles in total.
The probability of picking a red or blue marble would be 9 out of 12, since it is asking for either the red marble or the blue marble.
9/12 is the answer. (Simplifies down to 3/4)
