Number of remaining rose cards = 6
number of remaining cards = 8
P(rose card) = 6/8
P(blue marble) = 18/50
P(tail) = 30/50
P(blue marble and tail) = 18/50 x 30/50 = 540/2500
(a) 3x=4(x-2.25) (or simplified: 3x=4x-9)
(b) 3x=4x-9
0=x-9
x=$9
(c) 3x9=27
4x9=36
36-9=27
and 27=27 therefore they spent the same and it is correct
(d) Tanya's items cost $9 each and Tony's items cost $2.25 less than this, or $6.75
Step-by-step explanation:
Let p(x) be the profit function.
Area of top triangle = 1/2(3.5)(9) = 15.75
Area of bottom left triangle = 1/2(2)(2) = 2
Area of bottom right triangle = 1/2(2)(5) = 5
Area of square = 2 x 2 = 4
Area of figure = 15.75 + 2 + 5 + 4 = 26.75
answer
26.75 units^2
(5 + x)/6 = -1
Multiply both sides by 6.
5 + x = -6
Subtract 5 from both sides.
x = -11
