Answer:
D. 2/17
Step-by-step explanation:
Add all of the marbles: 6 blue marbles + 6 black marbles + 3 green marbles + 2 purple marbles = 17 marbles altogether.
Since there are 2 purple marbles out of 17 marbles in the paper sack, the complement to the probability that she will draw a purple marble is 2/17.
Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
here's the solution : -
if i made 9 costumes and it is 30 % of total costumes, so lets take the total number of costumes as <u>x</u><u> </u>
so, by above statement we get,
=》
=》
so, total number of costumes = 30 costumes.
Answer:
k = 11
Step-by-step explanation:
k/90 - 1/9 = 1/90
k/90 = 1/90 + 1/9
k/90 = 1 + 10/90
k/90 = 11/90
k = 11/90 / 90
k = 11/90 * 90
k = 11
The answer should be y=9 and y=-11
