people with type o-negative blood are universal donors. that is, any patient can receive a transfusion of o-negative blood. only 7.2% of the american population has o-negative blood. if 10 people appear at random to give blood, what is the probability that at least 1 of them is a universal donor?

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
