Answer:
<h2>9/6</h2>
Step-by-step explanation:
Remember that, to find the reciprocal of a fraction, just swap the numbers. So the reciprocal of 6/9 is 9/6.
Division CANNOT be commutative, here is why
lets say the problem is 24÷4
it is obviously 6
but when you flip 24÷4, you get 4÷24
and... 4÷24 is 0.16666666
6 and 0.1666 is totally different :p
4.00 - 3.65 = 0.35....so she saves 35 cents on each motivator
with 220 motivators...
0.35(220) = $ 77 <== what she saves
The solution is r= 7/a-x How did i do this?
Your equation is ax+ r=7, so the goal is to isolate the r. You begin by dividing the a from the ax. Remember, what you do to one side, you must do to the other. So you do 7/a, since you can't simplify 7/a, leave it as it is. Next, your equation should look like this x+r=7/a. In order to isolate the r, you move the x to the other side by subtracting, which leaves you with the answer of r= 7/a-x.
Hope this helped!
