Answer:
The son is five years old
Step-by-step explanation:
Let the son's age be x
A man is five as old as his son, 5x
In five years, he would be three times as old as his son
In five years: son would be x+5
Father 5x+5
3(x+5)=5x+5
3x+15=5x+5
Collect like terms
15-5=5x-3x
10=2x
Divide by 2
10/2=2x/2
x=5
The son is five years old
Hey! Just in case you have to show your work.
89(54x-36)+2=-3/4(-40+16x)+90x
4806x-3204+2=-3/4×4(-10+4x)+90x
4806x-3202=30-12x+90x
4806x-78x=30+3202
4728x=3232
3232÷4728=
X=404/591
Answer:
The answer is option A
Step-by-step explanation:
Reflection in the y axis is
(x , y) → ( - x , y)
The coordinates of A are ( 2, -5)
When it's reflected in the y axis it becomes
( - 2 , - 5)

36 divided by 4 = 9
so then you take 3 times 9 which is 27 so the answer is
g=27
Answer:
The answer to your question is: the first option - 9/ 
Step-by-step explanation:
Process
cosФ = adjacent side / hypotenuse
-1/9 = adjacent side / hypotenuse
adjacent side = -1 hypotenuse = 9
c² = a² + b²
b² = c² - a²
b² = 81 - 1
b = 
b = opposite side
But b is negative because we are in the third quadrant.
b = -
Finally csc Ф = hypotenuse / opposite side
csc Ф = - 9 /
