i have attached a tree diagram to help with your understanding, first branches show probability of picking either green or red the first time she picks one. The next set of branches show the updated probabilities after one pencil has been taken out.
Answer:
y = -5/9
Step-by-step explanation:
Answered it by using Photo Math :)
this needs a system
140=5x+10y
y= 2x-1
Now subsitute 2x-1 in for y
140=5x +10(2x-1)
140 = 25x -10
bring over the 10
150 = 25x
the divide
x = 6
now substitue x in in 2x-1
2(6) -1 = 11
there you have it, you have 6 five dollar bills and 11 ten dollar bills.
Answer:
No, because when j = 8, the values of the expressions are different.
Step-by-step explanation:
if its wrong i'm sorry
According to the Pythagorean Theorem, in a right triangle, the the squares of the sides equal the square of the hypotenuse. if the sides were to be A and B and the Hypotenuse were to b C, A²+B²=C². In your case, A=10 and C=10. If you were to plug that into the Pythagorean Theorem, 100+B²=100. (10²=100) If you subtract 100 by both sides (100=100 so they cancel each other out), B²=0. in a right triangle, a leg cannot equal 0. Therefore, A right triangle cannot have a leg that is 10 meters long and a hypotenuse that is 10 meters long.
