My grandson is about as many days as my son in weeks, and my grandson is as many months as I am in years. My grandson, my son and I together are 120 years. Can you tell me my age in years ?

Answers

x - your son's age in years
y - your age in years

There are 52 weeks in a year and 365 days in a year, so the age of your grandson in years is (52x)/365
There are 12 months in a year, so the age of your grandson in years is y/12.

Set both expressions equal to each other:
$(52x)/(365)=(y)/(12) \n52x * 12=365y \n624x=365y \nx=(365)/(624)y$
Your son's age is equal to 365/624 of your age.

Your grandson, your son and you together are 120 years.
$(1)/(12)y+(365)/(624)y+y=120 \n(52)/(624)y+(365)/(624)y+(624)/(624)y=120 \n(1041)/(624)y=120 \ny=120 * (624)/(1041) \ny \approx 72$

You are 72 years old.

Let m be my age in years.If s is my son's age in years, then my son is 52s weeks old. If g is mygrandson's age in years, then my grandson is 365g days old. Thus,
365g = 52s.
Since my grandsonis 12g months old,
12g = m.
Since my grandson,my son and I together are 120 years,
g + s + m = 120.
The above system of3 equations in 3 unknowns (g, s and m) can be solved as follows.
m / 12 + 365 m /(52 x 12) + m = 120 or
52 m + 365 m + 624m = 624 x 120 or
m = 624 x 120 /1041 = 72.
So, I am 72 yearsold.

The problem is hard...i don't know if you understood this..Hope i helped!

What percent of 67 is 26.8

Answers

If you would like to know what percent of 67 is 26.8, you can calculate this using the following steps:

x% of 67 is 26.8
x% * 67 = 26.8
x/100 * 67 = 26.8 /*100/67
x = 26.8 * 100 / 67
x = 40%

Result: 40% of 67 is 26.8.

26.8 is 40% of 67 :))

2x-8 what is the answer

Answers

2x-8if it means2 times -8 then 2 times -8=2 time s8 times -1=16 times -16if it is x is a placeholder then undistribute whereab+ac=a(b+c)so2x-82(x)-2(4)=2(x-4)so the factored form is 2(x-4)there is no equation so we cannot solve for x2x-8 could be equal to 3 or pi for all we know

The answer is x - 4.

You have to isolate the variable so you divide 2 from both sides leaving you with x - 4. Since you can't simplify it anymore, the answer will be x - 4. Hope I helped.
