<span>draw out a triangle and then create three boxes inside by drawing a T. In each of the boxes you've created you need to put one of the letters from the equation. The equation you currently have is F= m*a. To rearrange this equation put the m and the a into the bottom boxes and the F above. Because there is a vertical line between the m and the a, this means you times them. If there is a horizonal line between two letters you divide them. So to find a, you must divide F by m. </span>
Answer:
A. x+20=60
Step-by-step explanation:
Start with what you know: Alex has $68 and that is $20 more than Michael. Think, what number is 20 less than 68? The number is 48. You can plug 48 in for x in each answer choice or you can derive the answer by creating your own equation. Make x=how much Michael has. Since Alex has $20 more dollars, Michael has 20 fewer dollars than Alex. so x=68-20. The only answer choice that is equal to that is A.
