Answer:

80 ways

Step-by-step explanation:

The first thing is to apply the Fundamental Counting Principle with two groups of items, in this case the multiplication rule is used.

In this case, what we should do is that, for every 1 main course there are 8 appetizers, but there are 10 main courses therefore:

8 * 10 = 80

There are 80 ways to combine appetizers and the main course

How can u get hundred as a denominator as 209 over 25
satela [25.4K]

Hundred as a denominator as 209 over 25 is obtained by mulyiplying numerator and denominator by 4

\frac{209}{25} = \frac{836}{100}

<em><u>Solution:</u></em>

Given that we have to get hundred as a denominator as 209 over 25

Thus the given fraction is:

\rightarrow \frac{209}{25}

Now we have to get 100 as denominator

If you multiply both the numerator and denominator of a fraction by the same non-zero number, the fraction remains unchanged in value.

Therefore, equivalent fractions can be created by multiplying or dividing the numerator and denominator by the same number

Muliply and divide by 4, so that 25 muliplied by 4 gives 100

\rightarrow \frac{209}{25} = \frac{209 \times 4}{25 \times 4} = \frac{836}{100}

Thus the denominator is 100

Solve for x.<br><br> x−1/4=3/8
valentinak56 [21]

<u><em>x=5/8 is the correct answer.</em></u><em>  </em>First you had to simplify from both sides of equation, and it gave us, x+\frac{-1}{4}=\frac{3}{8}. Then you add 1/4 from both sides of equation, and it gave us, x+\frac{-1}{4}+ \frac{1}{4}= \frac{3}{8}+ \frac{1}{4}. And it gave us the answer is<u><em> </em></u><u><em>x=5/8 is the final answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
