Answer: B) -11
Step-by-step explanation:
2 (x+22) + 5 = 27
-5 -5
2x+44 = 22
- 44 -44
2x = -22
/2 /2
x = -11
Answer:
13 / 19
Step-by-step explanation:
Given that :
U = 130
Let :
s = swimming pool
t = track
g = gym
n(g) = 61 ; n(s) = 68 ; n(t) = 60
n(g n s) = 25 ; n(t n s) = 30 ; n(g n t) = 19
n(g n s n t) = 6
n(g n t) only = n(g n t) - n(g n s n t) = 19 - 6 = 13
Hence, probability that a randomly scted person uses the gym and track and does not use the swimming pool = n(g n t) only ÷ n(g n t)
= 13 / 19
= 13 / 19
Answer:
13
Step-by-step explanation:
12 - 0 = 12
0 - 5 = -5 which is same as 5 here
12^2 + 5^2 = 144 + 25 = 169
sqrt 169 = 13
5x5x5=125 so it could be x=5
