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.
