Answer:
C) ½
Step-by-step explanation:
In the given inequality statement: 2/5 < x < ¾
It means that, "<em>x</em> is less than ¾ and greater than 2/5."
Find out what the equivalent decimal values of each expression.
2/5 < x < ¾:
2/5 = 0.40
¾ = 0.75
Therefore, the value of x must be between 0.40 and 0.75.
A: 3/10 = 0.30 (not a solution for x).
B: 1/3 = 0.33 (not a value for x).
C: 1/2 = 0.50 (possible value for x)
D) 4/5 = 0.80 (not a value for x).
E) 5/6 = 0.83 (not a value for x).
As you can see, the only viable solution for x is ½, as it provides a true inequality statement: 2/5 < ½ < ¾
Therefore, the correct answer is C: ½

Answer:
143.75X = Y
Explanation:
Since I had to hire a plumber to come fix a leaky pipe, and the first day he worked 3 hours and charged me $ 450, while the next day he came back and finished the job working another 5 hours charging me $ 700, to find the equation that represents the cost, and, after x hours of working, the following calculation must be performed:
(450 + 700) / (3 + 5) = Y
1150/8 = Y
143.75 = Y
Thus, the hourly cost of the plumber's work was $ 143.75.
