We can start by solving for 10-5a+(18-b). By plugging in a and b, we get
10 - 10 + (18 - 11)= 7
28 ÷ (a × 2) = 28/4 = 7
20 + b − (4 × a) = 31 - 8 = 23
49 − 43 + (a ÷ a) = 49 - 43 + 1 = 7
30 − 25 + (b − 9) = 5 + 2 = 7
50 ÷ a − (b + 20) = 25 - 31 = -6
So, 28 ÷ (a × 2), 49 − 43 + (a ÷ a), and 30 − 25 + (b − 9) will all have the same answer as 10−5a+(18−b)
Answer:
x = 
Step-by-step explanation:
2x – 4 – (x + 2) = 6x is the given equation
Now simplifying both sides, we get
2x - 4 - x - 2 = 6x
taking like terms on each side of the equality, we get
2x - x - 6x = 4 + 2
or, -5x = 6
or x = 
hence, the value of x = 
372.634 is the answer to this equation
Answer:
The probability of a chain defect is 3%.
Step-by-step explanation:
Given : A bicycle manufacturer is studying the reliability of one of its models. The study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent.
If the probability of a defect with the brakes or the chain is 6 percent
To find : What is the probability of a chain defect?
Solution :
Let A be the event of brake defect
and B be the event of chain defect.
We have given, P(A)= 4%=0.04
P(A and B) = 1%=0.01
P(A or B)= 6%=0.06
We have to find P(B),
The formula used is,

Substitute the value,




or 
Therefore, The probability of a chain defect is 3%.
