The coordinates of the midpoint of two points A and B are the averages of the corresponding coordinates of A and B.
So if one point is (a, b) and another point is (c, d), the point exactly between them has coordinates ((a+b)/2, (c+d)/2).
In this example, the points
A(-3a, b)
B(3a, b)
have midpoint
F((-3a+3a)/2, (b+b)/2) = F(0, 2b/2) = F(0, b)

The two interior angles that are not supplemantly (adjacent) to the exteroir angle add up to the exterior angle. Therefore we have:
3x+2x=150
5x=150
x=30.
Since it asked for angle BAC, therefore we have:
30 x 2 = 60.
The answer is C.
Hope this helps!
Answer: 120 lb of potatoes.
Step-by-step explanation:
Let the pounds of potatoes sold by farmer Bill = X lb
Fractional part sold to the first person = 1/4
Therefore 1/4 of X = 1/4 x X
= X/4 lb of potatoes.
No of potatoes left for sale = X - X/4
= ( 4x - x )/4
= 3x/4 lb.
Fractional part sold to the second person out of the reminder = 4/9
Therefore 4/9 of 3x/4 = 4/9 x 3x/4
= x/3 lb of potatoes.
Amount of potatoes left for sale = 3x/4 - x/3
Resolve into fraction , we have = (9x - 4x)/12, because 12 is the LCM.
= 5x/12
Third buyer bought 4/5 of the left over = 4/5 of 5x/12
= x/3 lb of potatoes.
Amount of potatoes left = 5x/12 - x/3
Resolve in to fraction again taking 12 as the LCM = ( 5x - 4x )/12
= x/12 lb of potatoes .
Therefore, the left over was 10 lb .
To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to x/12 = 10
we now cross multiply to get the value of x x = 120 lb.
therefore the pound of potatoes sold by farmer Bill = 120 lb.
Answer:
120 potatoes
Step-by-step explanation:
solve
for
x.
(8x +9) = 5x-24
How to get x
X= -11 SUBTRACT 9 on both sides then you get 8x=5x-33 then subtract 5x from both sides then you get 3x=-33 then divide 3 from both sides then you get x=-11
