Answer: $\frac{\sqrt{77}}{22}$

Step-by-step explanation:

Given:

$\frac{\sqrt{7}}{2\sqrt{11}}$

Since the denominator is a surd , to simplify , all we need do is to rationalize

That is

$\frac{\sqrt{7}}{2\sqrt{11}}$ × $\frac{\sqrt{11}}{\sqrt{11}}$

⇒ $\frac{\sqrt{77}}{2(11)}$

⇒ $\frac{\sqrt{77}}{22}$ which is the simplified form of $\frac{\sqrt{7}}{2\sqrt{11}}$

It will cost Amber an estimated $3,723 a year in tuition to attend her preferred college. She has been putting $350 a month in a

kenny6666 [7]

Answer:

Yes; she will have $4008 for other expenses.

Step-by-step explanation:

First you find out how much she saved by multiplying 350 by 36 as she saved for 3 years which is 36 months.

$350 \times 36 = 12600$

After that you need to work out the amount she needs in total for her tuition by multiplying 4 by 3723 which is the amount needed per year.

$3723 \times 4 = 14892$

If her parents add to her account half the amount she saved that means that they give her an additional 6300 as that's half of 12600.

This means she has 18900 and if you take away 14892 you will be left with 4008 for expenses.

Simplify 2x+2y=8 by dividing by 2 throughout the entire equation. It becomes x+y = 4. This equation matches B.
