Answer:
A) x + y = 8
B) 3x + 2y = 21
We multiply A) by -2
A) -2x -2y = -16 Then we add this to
B) 3x + 2y = 21
x = 5
y = 3
Second answer is correct
Step-by-step explanation:
Answer: The answer is The radius is 2 inches, and the height is 3 inches. Since the diameter is 4 inches, the radius is half of 4 inches. The volume is 12π=22πh, which means 12π=4πh and h=3.

Answer:
(A) 1,663,200
(B)330
Step-by-step explanation:
<u><em>(A) </em></u>To do this you would just have to know the combimations formula which is
and when you plug in the numbers you get
which when simplified is
which is 1,663,200
<u><em>(B)</em></u> To do this you would just have to know the permutation formula which is
so if we plug in all of the numbers we would get
then we can divide 7 from both sides so we get
and when you simplify you get
which when reduced is 330

Answer:
K= -240
2/6k + 80 = 3/6k +120
2/6k -2/6k + 80 = 3/6k-2/6k +120
80 = 1/6k + 120
80 -120 = 1/6k +120 -120
-40 = 1/6k
-40 / 1/6 = 1/6k / 1/6
k = -240
