Question 1044855: If 4A = I and 8A = U, show algebraically the number of I's
needed to equal one U. Found 3 solutions by josgarithmetic, Edwin McCravy, MathTherapy:Answer by josgarithmetic(39620) (Show Source):
Let n = the number of I's needed to equal one U.
Then
nI = U
Substitute 4A for I and substitute 8A for U
n(4A) = 8A
Solve for n:
Simplifying:
4nA = 8A
Divide both sides by 4A
So we need 2 I's to equal one U.
