Answer:
20
Step-by-step explanation:
if two trapezoids are the same proportions, and one is 3cm, and the other is 15, the makes that second 5 times larger than the first. therefore, the height is also 5 times larger
4 x 5=20
(2,4) and (5,13) is m=-1/3 and (4,5) and (9,-3) is m=-8/5
Combine like terms: (6y+y)+(-4)= 7y-4
Answer:
P (black marble) =3/11
Step-by-step explanation:
We need to find the total number of marbles
4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles
We take away a black marble and throw it away
3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles
The probability of drawing a black marble is
P (black marble) = black/total
=3/11
