The answer to your question is C, and D. The way that you get this is by multiplying. To get 20, you multiply 2/5 by 4 to get 8/20, and you multiply 3/10 by 2 to get 6/20. To get 10 as a denominator for 2/5 you multiply by 2/5 to get 4/10, and you do not have to do anything to the 3/10 because the denominator is already 10. Then you just compare the numbers on the top to determine the larger fraction.

if you've read those links already, you'd know what we're doing here.

we'll move the repeating part to the left-side of the dot, by multiplying by "1" and as many zeros as needed, or 10 at some power pretty much.

on 0.13 we need 100 to get 13.13.... and on 0.1234, we need 10000 to get 1234.1234....

\begin{array}{|lll|ll}

100\cdot 0.\overline{13}& = & 13.\overline{13}\\
100\cdot x&& 13 + 0.\overline{13}\\

\cline{1-3}

10000\cdot 0.\overline{1234}&=&1234.\overline{1234}\\
10000\cdot x&=&1234+0.\overline{1234}\\
10000x&=&1234+x
\\&&\\
\cline{1-3}
\end{array}\implies \begin{array}{llll}
10000x=1234+x

9999x=1234\implies x=\cfrac{1234}{9999}

Total gasoline = 10 gallons

Gasoline left after 100 miles = 5 gallons

Gasoline used in 100 miles

= Total gasoline - Gasoline left after 100 miles

= 10 gallons - 5 gallons

= 5 gallons

Gasoline used in 1 mile

= Gasoline used in 100 miles/100

= 5 gallons/100

= 0.05 gallons

Which expression is equivalent to 1/6 (2x+3y)
gogolik [260]

Answer:

x/3+y/2

Step-by-step explanation:

Hello, to find the equivalent expression in this equation, you would first distribute the 1/6 to 2x+3y like this:

2x(1/6)+3y(1/6)

Then, you multiply and you would get x/3+y/2. And that would be the answer.

Solve for the value of S.
fomenos
<h2>Answer:</h2>

s = 18°

<h2>Step-by-step explanation:</h2>

The figure has been re-labelled to show additional information and description and has been attached to this response.

As shown in the figure, line AB is a straight line.

The angles on the straight line are <em>6s + 2</em> and <em>4s - 2</em>

<em></em>

Since the sum of angles on a straight line is 180°, it therefore implies that;

<em>6s + 2</em> + <em>4s - 2 = 180°</em>

<em></em>

<em>Solve for s by collecting like terms and simplifying</em>

6s + 4s + 2 - 2 = 180

6s + 4s = 180

10s = 180

s = 18°

Therefore, the value of s is 18°
