Let one factor be x
the other factor = 0.5x - 11

x(0.5x - 11) = -36
0.5x² - 11x + 36 = 0
x² - 22x + 72 = 0
(x - 18)(x - 4) = 0
x = 18 or x = 4

When x = 18
0.5x - 11 = 0,5(18) - 11 = -2

When x = 4
0.5 - 11 = 0.5(4) - 11 = -9

-------------------------------------------------------------------------
Answer: The pairs are (18 and -2) and (4 and -9)

Gabbys age is two times mikhails age.the sum of their ages is 75. What is mikhails age
Tatiana [17]

Answer:

Mikhail's age is 25 years old

Step-by-step explanation:

Let's make an equation: Say Mikhail is x, so Gabby would be 2*x=2x

If the sum of their ages equals 75, then x+2x=75, and x=2x=3x, so 3x=75.

75/3=25
