In an athletic meet, 40% of athletes are participating in running race, 30% of them are participating in long jump, and 10% of them are participating in both the above events. The remaining athletes are
participating only in shot-put, if there are 80 athletes in all, how many athletes are participating only in
long jump?​

16

Step-by-step explanation:

80100%

?20%

80*20= 160

160/100= 16

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

u

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
