Answer:
w = 4cm L = 5 cm
Step-by-step explanation:
w = w
L = 2w - 3
P = 18 = 2L + 2w
18 = 2(2w-3) + 2w
18 = 4w -6 + 2w
18 + 6 = 6w
24 = 6w
w = 4 cm
L = 2w - 3
L = 2(4) -3
L = 8 - 3
L = 5 cm
Answer: 29/139
Explanation:
Total student: 139 (66 boys/73 girls)
Football: 56 student (28 boy/28 girl)
Tennis: 54 student (27 boy/ 27 girl)
Running: 29 student (18 girls/11 boys)
The probability that a student chose running is 29/139
Divide -9 from both sides which results in a flip of the sign (dividing or multiplying a negative to both sides results in a flip of the sign!)
You now have
y =< -8
