At Acme Inc., there are 3 more than twice as many salespeople as inventors. If the whole company has 27 employees,
Olenka [21]

Answer:

There are 8 inventors.

Step-by-step explanation:

  • Let 's' be the salesperson
  • Let 'i' be the inventors

Given that there are 3 more than twice as many salespeople as inventors.

  • i.e s = 3+2i

Also given that the whole company has 27 employees.

i.e.

s + i = 27

substituting s = 3+2i

3 + 2i + i= 27

3 + 3i = 27

3i = 27 - 3

3i = 24

divide both sides by 3

i = 8

  • Thus, there are 8 inventors.

<u>VERIFICATION</u>

As the total number of employees is 27.

so the salespeople will be:

s = 3+2i

  = 3 + 2(8)

  = 3 + 16

  = 19

Thus, the total employees are verified as:

s + i = 27

19 + 8 = 27

27 = 27

What is the factored form of the following expression? <br><br> W^2 + 18w + 77
Lorico [155]

Answer:

(w + 11)(w + 7)

Step-by-step explanation:

Consider the factors of the constant term ( + 77) which sum to give the coefficient of the w- term ( + 18)

The factors are + 11 and + 7, since

11 × 7 = 77 and + 11 + 7 = + 18

w² + 18w + 77 = (w + 11)(w + 7)
