Hello !

\sqrt{2n+28}-4\sqrt{n}=0\\\\\sqrt{2n+28}=4\sqrt{n}\\\\\sqrt{2n+28}^2=\left(4\sqrt{n}\right)^2\\\\2n+28=16n\\\\2n-16n=-28\\\\14n=28\\\\\boxed{\boxed{n=2}}

How much sugar syrup would you get by Making 5% sugar syrup using 6g sugar?
kherson [118]

Answer: 120 grams.

Step-by-step explanation:

Let x be the amount of sugar syrup made by 5% sugar syrup using 6g sugar.

Also, 5% =0.05

Therefore, 5% sugar syrup =5% of x = 0.05x

According to the question, we have

0.05x=6\\\text{Divide 0.05 on the both sides we get}\\\Rightarrow\ x=\frac{6}{0.05}\\\Rightarrow\ x=\frac{600}{5}\\\Rightarrow\ x=120

Hence, 120 grams sugar syrup is made by 5% sugar syrup of 6g sugar.
