$\boxed{x = 20}$

There is only one step to this equation. We use inverse operations to isolate the x by dividing 2 on both sides; because 2 is being multiplied by x, and the inverse operation for multiplication is division.

2x/2 = x

40/2 = 20

The equation now looks like:

x = 20

This is your answer.

Bess [88]

Answer:

Hope this helps

Step-by-step explanation:

1. Make 5 3/4 into an improper fraction. That would be 23/4. 2. Write 4 in a fraction way. That would be 4/1. 3. Now do 23/4 X 4/1. That would be 92/4. 4. Turn it into a mixed number by doing 92 divided by 4. That would be 23. No fraction after 23. Jacob rode his bike 23 miles this week. :)

Thirty five percent of the employees in a company have managerial positions, and 67 percent of the employees in the company have

seraphim [82]

Answer:

49% of employees who either have MBA or are managers.

Step-by-step explanation:

We are given the following information in the question:

P(Managerial) = 35% = 0.035

P(MBA) = 67% = 0.67

$P(\text{Managerial} \cap \text{MBA}) = 53\% = 0.53$

We have to find the probability of employees who either are have MBA or are managers.

According to De-Morgan's law:

$P(\text{Managerial} \cup \text{MBA}) = P(\text{Managerial}) + P(\text{MBA}) - P(\text{Managerial} \cap \text{MBA}) \\P(\text{Managerial} \cup \text{MBA}) = 0.35 + 0.67 - 0.53 = 0.49$

Thus, around 49% of employees who either have MBA or are managers.
