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
Y^2 -11y = 0
We can factor it:
y * (y -11) = 0
So y = 11, 0
1- 0.25= 0.75 (multiplier)
33÷0.75=44
The suitcase originally weighed 44kg
Hope this helps!
Take out common factor, 3 :
3x - 3 = 3(x - 1)

Answer:
$11.65
Step-by-step explanation:
20% of 58.25, "of" in math means multiplication. So you multiply it.
To get 20% as a fraction you move the decimal 2 places to the left, and it's .2 or .20 so you get this equation:
.20 * 58.25
So your answer is, $11.65.
To find the total of the bill including the tip it would just be
11.65 + 58.25 = 69.90
