a nutritionist finds that a large order of mc donalds fries has more fat than a quarter pounder. the fries have 4 more grams than 3 times the amount of fat in the quarter pounder. the difference between the two is 46 grams. find the fat content of the hamburger and of the fries.
Fries + 4g = 3*Burger Fries - Burger = 46g (not Burger - Fries since it says Fries is larger) solve one system for either Burger or Fries and plug it into the other system
can u please work it out for me....this is what i got so far|dw:1349412941402:dw|
thts whut i put together from whut yu told me.....
that's right! now solve one equation for y or x. I would suggest you re-write the second equation as y = 46 + x (just take x to the other side). Now put (46 + x) into y in the first equation.
everything will be in terms of y, so you can solve for y. Then plug y back into 2nd equation and you will find x!
