Answer:
bc they are placed the same if one is multiplied by 10. or you could just multiply the tens place and add that to your 100
140=14×10 and 100 and 4 tens is written 140.
So probility is (disired outcomes) divided by (total possible outcomes) so
1st one is white roses
8 white roses so 8 is disired
total=5+3+8=16
8/16=1/2
then without replacing them
red=5
total possible=16-1 since 1 picked
5/15=1/3
then multiply the probatilities
1/2 times 1/3=1/6
it is a 1 in 6 probability
Let R be the event that a red card is drawn. There are two red suits of 13
cards each, so there are 26 ways of getting are red card. There are 52 cards
altogether, so the probability of getting a red card is
P(R) = 26
52
=
1

- 8 ( x + 2 ) + 5x = - 4
Start by distributing.....
- 8 x - 16 + 5x = - 4
Combine like terms.....
- 3 x - 16 = - 4
Add 16 to both sides.....
- 3x = 12
Divide both sides by -3 to get x by its self.....
x = - 4 is the answer
