Answer:
x=68.5
Step-by-step explanation:
<u><em>Let's solve your equation step-by-step.
</em></u>
−39.7+x=28.8
<em><u>Step 1: Simplify both sides of the equation.
</u></em>
x−39.7=28.8
<u><em>Step 2: Add 39.7 to both sides.
</em></u>
x−39.7+39.7=28.8+39.7
<em>x=68.5</em>
OK. Then let's solve for ' r '. That means you have to come up with an equation that says r = everything else.
Step #1:
Write the equation you're given: <span>S = L (1 - r)
Let's divide each side by ' L ': S/L = 1 - r
Subtract 1 from each side : S/L - 1 = -r
Multiply each side by -1 : <em> 1 - S/L = r</em>
and there you have it.
