The equation is 30x + 25
since the x is with the 30, that would be the cost per lesson, because you would multiply 30 by the number of lessons(x)
Answer:
x = -
, x = 
Step-by-step explanation:
Given
x² - x -
= 0
Multiply through by 4 to clear the fraction
4x² - 4x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × - 3 = - 12 and sum = - 4
The factors are + 2 and - 6
Use these factors to split the x- term
4x² + 2x - 6x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(2x + 1) - 3(2x + 1) = 0 ← factor out (2x + 1) from each term
(2x + 1)(2x - 3) = 0
Equate each factor to zero and solve for x
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - 
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = 
There are 50 employees in total
<h3>How to determine the total employee?</h3>
The given parameter is:
Part-time = 8% of total employee
Rewrite as:
Part-time = 8% * total employee
There are 4 part-time employees.
So, we have:
8% * total employee = 4
Divide both sides by 8%
total employee = 50
Hence, there are 50 employees in total

Answer:
I think the answer is 87
Step-by-step explanation:
Answer: B, Equivalent 0.4(k+3) = 0.4k +1.2
Step-by-step explanation:
when you distribute the 0.4 across k and 3, you multiply 0.4 by k and 3, getting you 0.4k+1.2 which is equivalent.
