If he ate 4 of them, but it means he ate 2/5 muffins,
4 muffins = 2/5 muffins
You substitute x muffins for how much muffins she baked in all -
2/5* x muffins = 4
2/5 multiply by 2/5 to cross it out. Do the same to the other side.
x= 4 *5/2
x = 10 muffins
So there were 10 muffins in all
6/54 times because there are 9 marbles and the orange marble is 1 out of those 9 marbles. If you multiply 6*9= 54 then you notice there is a 6/54 chance of picking any 1 marble out of the 54 times that you decide to pick marbles.

Answer:
<h2>(2x^2+5x-3)-(x^2+x-6)</h2>
Step-by-step explanation:
That is the only one I could find. It is a simple matter of simplifying each equation and seeing if it will match the given: x^2+4x+3. Make sure that you properly distribute and watch your signs (-/+)
