Answer:
He makes $15,000
Step-by-step explanation:
250,000*0.06 or 6%= 15,000
The positive solution will be "x = 3, -9". To understand the calculation check below.
According to the question,
Let,
The number be "x".
6x = x² - 27
Now,
x² - 6x - 27 = 0
By applying factorization, we get
→ x² - 3x + 9x - 27 = 0
By taking common,
x (x - 3) + 9 (x - 3) = 0
(x + 9) (x - 3) = 0
(x + 9) = 0
x = -9
or,
(x - 3) = 0
x = 3
Thus the answer above is correct.
Find out more about factorization here:
Let x = your number.
6x = x^2 - 27. Subtract 6x from each side.
0 = x^2 - 6x - 27. Factor
0 = (x-9) (x+3). Set each term equal to zero
(x+3) = 0. Subtract 3 from each side.
x = -3. This is the negative solution.
(x-9) = 0. Add 9 to each side.
x = 9. This is the positive solution.
4 3/8 so need to know how many times 8 goes into 35.
the answer is 4 3/8
21-(-55)
