Answer: 4(x +1)
You get that answer because first you subtract the numbers and find your common factor so the answer is 4(x + 1)
1 yard = 36 inches
so 720 inches = 720/36 = 20 yards.
4.75 lbs of water and 0.25 lbs of sugar is needed to make 5% of syrup.
<u>Solution:</u>
Let us assume that x is the required pounds sugar to make 5% syrup

which is 
On solving we get,
![\Rightarrow\frac{x}{5} =0.05 [5\%=\frac{5}{100}]](https://tex.z-dn.net/?f=%5CRightarrow%5Cfrac%7Bx%7D%7B5%7D%20%3D0.05%20%5B5%5C%25%3D%5Cfrac%7B5%7D%7B100%7D%5D)

If the required sugar to make 5% syrup is 0.25 lbs then the remaining quantity in the total sugar syrup would be water. That is,

So, the required amount is 0.25 lbs of sugar and 4.75 lbs of water.
