- Let r represent Rick’s height.
- Therefore, the quotient of Rick’s height and 4
- Fred is 5 inches shorter than the quotient of Rick’s height and 4.
- Therefore, an expression that represents Fred’s height is
Answer:
Hope you could get an idea from here.
Doubt clarification - use comment section.
Each person gets 2 step by step explanation
False the Pythagorean theorem is A2+B2=C2 hope this helps!
Let's say the original price was "x", thus "x" is the 100%, and we know that 15 is 80% of that, thus
as you already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".
