Answer:
c
Step-by-step explanation:
you would put -142 in the x place
-0.2(-142+223)
-0.2(81)=-16.2
If it's just the 7 that's repeating, let
<em>x</em> = 0.1777...
Then
10<em>x</em> = 1.777...
100<em>x</em> = 17.777...
100<em>x</em> - 10<em>x</em> = 17.777... - 1.777...
90<em>x</em> = 16
<em>x</em> = 16/90 = 8/45
If both 1 and 7 are repeating, let
<em>x</em> = 0.171717...
Then
100<em>x</em> = 17.171717...
100<em>x</em> - <em>x</em> = 17.171717... - 0.171717...
99<em>x</em> = 17
<em>x</em> = 17/99
Answer:
76
Step-by-step explanation:
when i text my boy he is ute
A:4*7=28. so there are 7 multiples upto 30. P(A)=7/30
B:26,27,28,29 i.e. 4 numbers satisfy the 2nd criteria. P(B)=4/30
P(A∩B)=1/30 (since 28 belongs to both A&B)
P(A∪B)= P(A)+P(B)-P(A∩B)= (7+4-1)/30= 1/3
Answer:
His friend won 10 games.
Step-by-step explanation:
In order to find this, divide the number of games that he won by his part of the proportion (7).
35/7 = 5
5 in this case is the scale factor. We can now multiply his friend's winnings to get the total number of his wins.
5 * 2 = 10
