5 DIVIDED BY 1/4 hURRY PLEASE

Anni [7]

Hello!

1/4 is equal to 0.25. Let's divide below.

5/0.25=20

When dividing by fractions, you multiply by the reciprocal. The reciprocal of 1/4 is 4, and 5(4)=20

Therefore, our answer is 20.

I hope this helps!

Use the following work shown below to answer the following question.

zysi [14]

Answer:

$\frac{3 + \sqrt{3x} }{3 - x}$

Step-by-step explanation:

You can use the work they gave you and continue from there:

$\frac{\sqrt{3}(\sqrt{3}) + \sqrt{3}(\sqrt{x}) }{(\sqrt{3}) ^{2} - (\sqrt{x} )^{2} }$

First, simplify the numerator:

$\frac{3 + \sqrt{3x} }{(\sqrt{3}) ^{2} - (\sqrt{x}) ^{2} }$

Finally, simplify the denominator:

$\frac{3 + \sqrt{3x} }{3 - x}$

A family member has some five dollar bills and one dollar bills in their wallet. Altogether she has 18 bills and a total of $62.

Pepsi [2]

X - the number of five dollar bills
y - the number of one dollar bills

She has 18 bills in total.
$x+y=18 \\ y=18-x$

She has $62.
$5x+y=62 \\
y=62-5x$

Set both expressions equal to each other:
$18-x=62-5x \\
-x+5x=62-18 \\
4x=44 \\
x=11 \\ \\ y=18-x=18-11=7$

She has 11 five dollar bills and 7 one dollar bills.
