Answer:
you substitute x for 4 and so you multiply 9 x 4 which will give you 36 and then you have to add four times y so you substitute y for -3 and you add 36 - 12 which will give you 24
-- "Perimeter" means all the way around, all four sides.
-- That's two lengths and two widths.
-- So one length and one width is half of the perimeter.
-- If the perimeter is 16-ft, then one length + one width is 8-ft.
-- If the width is 5-ft, then the length is (8 - 5) = 3-ft.
Answer: is it 8
Step-by-step explanation: i just guess the middle number
Probability that you have chosen 2 red marbles is 3/11
<h2>How to solve?</h2>
Total number of marbles = 6 + 5 = 11
Number of red marbles = 6
Number of blue marbles = 5
Important Points:
1. Replacement is not allowed
2. Blue is followed by Red
Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.
Probability of Blue first = 5/11
Probability of Red second = 6/10 (one marble is already taken out)
Probability = 5/11 * 6/10 = 3/11
