10 + 20 = 30 total balls.
Picking red = 10/30 = 1/3
After picking one ball there are 29 balls left.
Picking a yellow next is 20/29
Then there are 28 balls left and 19 yellow left, so picking another yellow would be 19/28
The probability of picking red first then two yellow = 1/3 x 20/29 x 19/28 = 95/609
Each can of stain covers 50 square inches.
Hence, we need 7 cans of stain to cover at least 324 square inches.
In the coordinate plane, quadrilateral ABCD has vertices A(-2, 3), B(4,5), C(10, -1), and D(8, -9). Let E, F, G, and H

Answer:
G(3, 1), H(2, 3)
Step-by-step explanation:
When D is the midpoint of EG, it means ...
D = (E + G)/2
or
G = 2D -E = 2(3,4) -(3,7) = (2·3-3, 2·4-7) = (3, 1)
Likewise, H is ...
H = 2D -F = 2(3,4) -(4,5) = (2·3-4, 2·4-5) = (2, 3)
not my answer but i hope it helps you.
Answer:
x+4
x+1-2=x-1
Step-by-step explanation:
x+4/x-1=11/16 x should be different than 1 cz 1-1=0
16(x+4)=11(x-1)
16x+64=11x-11
16x-11x=-11-64
5x=-75
x=-15
