Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. How old is Kevin now?

Answers

Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d -  2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.

What is the solution to 1/3x-5+171=x

Answers

(1/3)x-5+171=x
I move the x on the right to the left so
(1/3)x-x-5+171=0
I then simplify so
(-2/3)x+166=0
I subtract 166 from both sides so
(-2/3)x = -166
Then I divide (-2/3) from both sides so
x = -166/(-2/3)
x = 249
and that's the answer
hope this helps
x in (-oo:+oo)

(1/3)*x-5+171 = x // - x

(1/3)*x-x-5+171 = 0

166-2/3*x = 0 // - 166

-2/3*x = -166 // : -2/3

x = -166/(-2/3)

x = 249

x = 249

You use 6 gallons of water on 20 plants in your garden. At that rate, how much water will it take to water 30 plants?

Answers

9 because if you split the planta up into 10's, you would split the gallons into 3's. Thats 3 gallons per 10 plants
To do this, set up a proportion.  The proportion would be 6/20=x/30.  To do this, multiply 30 by 6.  This gives you 180. Now you want to divide 180 by 20. This gives you 9.  It would take 9 gallons of water to water 30 plants.
