Answer:
x = 1
Step-by-step explanation:
Given
8 - 5(x - 3) = 18 ( subtract 8 from both sides )
- 5(x - 3) = 10 ( divide both sides by - 5 )
x - 3 = - 2 ( add 3 to both sides )
x = 1
Answer:
0.7
Step-by-step explanation:
Given a biased dice :
Probability of landing on 6 = P(6) ;
P(6) = 0.3
Recall :
P(A') = 1 - P(A)
Therefore,
If
P(6) = 0.3
P(not landing on 6) ; P(not 6) ;
P(not 6) = 1 - P(6)
P(not 6) = 1 - 0.3 = 0.7
Hence, Probability of not landing on 6 = 0.7
Log7+log(x-4)=1
Subtract log 7 from both sides
Log(x-4)=1-log7
As 1-log7 = log (10/7)
Log(x-4)=log (10/7)
As bases of logs are same.
we get
x-4=10/7
Add 4 to both sides
x=10/7 + 4
simplify
x=38/7
Answer: x=38/7
Answer:
x < 100
Step-by-step explanation:
x - 19 < 81
* add 19 to each side *
- 19 + 19 cancels out
81 + 19 = 100
x < 100
Answer:
21
Step-by-step explanation:
y = 3x + 9
y = -3x + 12
y=21
