7-12(3+b)=31
7-36+12b=31
-29+12b=31
12b=31+29
12b=60
b=5
Answer: d. mutually exclusive
Step-by-step explanation:
Mutually exclusive events are those events that cannot happen at the same time. If one event happens, the other has a zero chance of happening at the same time.
Event A and Event B here are Mutually Exclusive because you cannot turn left and right at the same time. If you listen to your brother and turn left, you cannot also listen to your sister and turn right at the same time.
Answer:
multiply and see what you get
Answer=46.43
39 84
___=____
x 100
cross multiply
84x=3900
divide both sides by 84
x=46.43
Answer:
Step-by-step explanation:
The midpoint between two points is the average of the coordinates.
mp=((x2+x1)/2, (y2+y1)/2)
In this case we are given one end point and the midpoint.
Just look at the x coordinate first.
If the mid x is 8 and the x from j is 10 we have
(10+x)/2=8
10+x=16
x=6, now for the y for j when y=6 and mid y of 5
(6+y)/2=5
6+y=10
y=4
So the coordinates of K are (6,4)
