<h2>85=36+x²</h2><h2>85-36=x²</h2><h2>49=x²</h2><h2>49½=x</h2><h2>x=7 </h2>
<span>To write this sum as a single fraction we need to put both of them over a common denominator. Our common denominator will be the simplest thing that has both 3 and 5 as a factor, which is 15 (x-2)/3 + (x+3)/5 = 5(x-2)/15 + 3(x+3)/15 Now we can put both numerators over the same denominator to get (5(x-2) + 3(x+3))/15 Next we should multiply out and simplify the numerator (5(x-2) + 3(x+3))/15 = (5x -10 +3x +9)/15 = (8x-1)/15
hope this helps but dont know if its right</span>
From all this information we can come up with a few equations to work with...
first we have that the worth of each coin times the number of those coins all added together equals 4.65
here I have n = nickels, d = dimes, and q = quaters
then we are told that there are "three more quarters than dimes"
which translates to the equation
or
we are also told that there are "twice as many nickels as quarters"
this translates to
to solve for quarters, we plug in d (in terms of q) and n (in terms of q) into the first equation we created.
then we distribute and start trying to solve for
then add like terms
then add 0.30 to both sides
then divide both sides by 0.45
therefore our answer is B) 11 quarters
