5x means 5 times x where x is some placeholder for a number. To get the inverse, we undo the multiplication. Division is the opposite of multiplication. So we'll divide both sides by 5 as one of the steps. Also, we'll swap x and y
y = 5x
x = 5y ... swap x and y
5y = x
5y/5 = x/5 .... divide both sides by 5
y = x/5
So this means the inverse function is equal to x/5
Answer:
I only know how to solve it, it is -3
Step-by-step explanation:
-8x+3> or = 18-3x
3>or= 5x+18
-15> or = 5x
x>or=-3
Answer:
(C) 18 muffins
Step-by-step explanation:
(12 cups)/(2/3 cups/muffin) = 12·3/2 muffins = 18 muffins

You can consider this as a unit conversion problem. You have units of cups, and you want units of muffins. Then you need to multiply by a number that has units of muffins/cup.
You have a number that has units of cups/muffin (the inverse of the desired conversion factor), so you can do the required conversion by <em>dividing</em> by that number.
720% is your answer! Think of it as money! 1/5 out of 100 is 20 cents, 7 is 7 dollars. 720 pennies all together so 720%! Hope this helps.
