Answer:
k = -2
Step-by-step explanation:
1. Substitute the point (2,-1) into the given equation 5x+ky=12. The first number is 2, the x-value. The second number is -1, the y-value.
5x + ky = 12
5(2) + k(-1) = 12
2. Simplify
5(2) + k(-1) = 12
10 + (-k) = 12
10 - k = 12
2. Isolate k
10 - k = 12
-k = 12-10
-k = 2 <= here multiply both sides by (-1)
k = -2

Every mixed number is (a whole number) + (a piece of another one).
So every mixed number must be bigger than ' 1 ', because ' 1 ' is the
smallest whole number.
77/200 is less than ' 1 ', because the numerator is less than the
denominator. So it doesn't have what it takes to be a whole number.
Every fraction is a short way to write a division problem. It means
(the top number) divided by (the bottom number).
When you actually do the division, the answer is the decimal form
of the fraction.
When you divide 77 by 200 , you get 0.385 .

The volume of the triangular prism is the Area of the base times the height
the area of the base is:
and the volume is:
now b=10 yards, a=20 yards, and V=600 yards^3
we clean the height
the answer is height = 6 yards
