you need to make the denominators that same and then you simply simplify the problem
9 4/12 = 9 1/3
Answer:
hope that helps
Step-by-step explanation:
3x^2+2xy+y2=2
6x + 2y + 2xy' + 2yy' = 0
x=1 ==> y=-1
6(1) + 2(-1) + 2(1)y' + 2(-1)y' = 0
6 - 2 + 2y' - 2y' = 0
4 = 0
(e) undefined
The graph is an ellipse. At (1,-1) there is a vertical tangent
Answer:
(5, 4) is correct.
First comes x, which is horizontal on the graph
Then comes y, which is vertical.
Don't know how to type the symbole infront of the 50 so I will subsitute
£50=$50
so 1:4
add it up
1+4=5
so 5 total units
$50=5 units
divide by 5
$10=1 unit
so 1:4=10:10 times 4=10:40
the answer is 10:40
Answer:
r=201
d = 77 1/2
Step-by-step explanation:
6) First multiply left and right by 16, to get rid of the fraction:
r - 25 = 11*16
Now add 25 left and right:
r = 11*16 + 25 = 201
7) Add 5 left and right
2/5 d = 31
multiply by 5/2
d = 31 * 5/2 = 77 1/2
