Make each of these an improper fraction, which would be 7/2 and 4/3. You can multiply these to get 28 / 6, and then you simplify to get 14/3, and if you were trying to make it a mixed number, just do 4 2/3
Let's start making our expression.
Just take the number 40 and change it around.

That's a good start.
49 is equal to 7×7, or 7². 9 is equal to 3×3, or 3².
So we can also write this as

You can really do whatever you want with it as long as it's still 40, just make sure you've got an exponent there. Here's another example.
Answer:
77 feet
Step-by-step explanation:
ratio
3:7=33:x
33/3=11
7*11=77
77 feet
You would subtract 3x from the left side, and get -2 = -2x, so x=1 would be your answer
