Solve this equation a{6a-2a}=b{2a-3b}

1 answer:

4 0

The "solution" of the equation would be a pair of numbers ... one
for 'a' and one for 'b' ... that make the equation a true statement.

If the equation has two variables in it, as this one does, then
you need two equations to find the solution.

The original cost of Sam’s investment is $10,000. After liquidating the investment, Sam calculated his real return to be $10,700

OverLord2011 [107]

Answer:

Return on investment (ROI) = 7%

Step-by-step explanation:

Given:

Amount invested = $10,000

Total amount get (refund) = $10,700

Find:

Return on investment (ROI) = ?

Computation:

Amount Return = Total amount get (refund) - Amount invested

Amount Return = $10,700 - $10,000

Amount Return = $700

$Return\ on\ investment \ (ROI) = [\frac{Amount\ Return}{Amount\ invested} ]100\\\\Return\ on\ investment \ (ROI) = [\frac{700}{10,000} ]100 \\\\ Return\ on\ investment \ (ROI) =7$

Return on investment (ROI) = 7%
