Hello! And thank you for your question!
First to make the question more easy to understand. We are going to make these three fractions improper fractions.
To do this I will give an example. 3 1/6. Do 6*3+1=19/6
Equation after made improper:
19/6 + 74/9 - 3/2
Now that we have this we can find the answer!

Work:
First you are going to find the LCD. And change all the numbers denominators to that LCD.
LCD = 18
Equation After incorporating LCD:
57/18 + 148/18 - 27/18
Second we are going to add all of the numerators together to get:
178/18.
Then simplify 178/18 to get:
89/9
Then convert 89/9 to a mixed fraction:
9 8/9
Final Answer:
9 8/9
The slope of a line is
. We have the points (3, -2) and (1, 8). Let's substitute those into the formula.
subtracting a negative is the same as adding, so that makes our equation
slope = -5
It’s 8 ÷ 2/5 = 20 because 20 x 2/5 = 8
The probability that a single radar set will detect an enemy plane is 0.9. if we have five radar sets, what is the probability that exactly four sets will detect the plane?
Solution: The given random experiment follows binomial distribution with
Let x be the number of radar sets that will detect the plane.
We have to find
Therefore, the probability that exactly four sets will detect the plane is 0.3281
M=14+f, m+f=34. Solve for the equations simultaneously.
one way is to substitute teh first into the second to get, 14+2f=34, or 7+f=17, or f=10. Since f is 10 and m+f=34, m=34-10=24.
Good luck!
