Uhhhhh the picture is all white
B is the best strategy. (You mentioned an option D, but it's not shown in your question!!)
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
<span> 5*(x-2)-4*(x+1)-(50)=0 </span>
There are 10 deciliters in 1 liter (deci means 10).
Divide 5.25 by 10 to find how many liters are needed.
5.25/10 = 0.525
0.525 liters of milk are needed for the cake.
1/2 * 2/3 *3/4 * ... * 1999/2000
Observe, every numerator cancels with denominator
that leaves 1/2000
