2n-1 over 18 equal 15 over 25
N = 13
are you solving for n?
(2n-1)/18 = 15/25
(2n-1)/18 = 3/5
cross-mulitply
10n - 5 = 54
etc
let me know what you got
To solve the equation (2n-1)/18 = 15/25, you can follow these steps:
Step 1: Simplify both sides of the equation.
Multiply both sides by the common denominator, which is 450 (the product of 18 and 25):
450 * [(2n-1)/18] = 450 * (15/25)
25(2n-1) = 18(15)
Step 2: Distribute and simplify.
50n - 25 = 270
Step 3: Isolate the variable.
Add 25 to both sides of the equation:
50n - 25 + 25 = 270 + 25
50n = 295
Step 4: Solve for n.
Divide both sides by 50:
50n/50 = 295/50
n = 5.9
Therefore, n is equal to 5.9.
