Question 897147: One number is four times a second number. If you take one- half of the second number and increase it by the first number, the result is at least 45. Find the least possible value for the second number. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! let a = the 1st number
let b = the 2nd number
:
Write an equation for each statement
:
One number is four times a second number.
a = 4b
:
If you take one-half of the second number and increase it by the first number, the result is at least 45.
.5b + a => 45
Replace a with 4b
.5b + 4b => 45
4.5b => 45
b => 45/4.5
b => 10 the 2nd number
