Answer:

Yes, there's enough popcorn for eight 9-ounce bags

Step-by-step explanation:

we know that

Eight 9-ounce bags is equal to

8*9=72\ ounces

so

By proportion find the amount of popcorn made by each machine

Machine A

\frac{12.75}{3}=\frac{x}{10}\\ \\x=12.75*10/3\\ \\x=42.5\ ounces

Machine B

\frac{18}{4}=\frac{x}{10}\\ \\x=18*10/4\\ \\x=45\ ounces

so

42.5\ ounces+45\ ounces=87.5\ ounces

87.5\ ounces> 72\ ounces

therefore

There's enough popcorn for eight 9-ounce bags

The quotient of a secret number and 4 is 9
Anna [14]
Let's call the 'secret number' <em>x</em>.

A quotient is basically a Dividend/Divisor. If the Divisor is 4, we need to find the dividend, which is <em>x</em>.

<em />Therefore:
<em>x/4=9
</em><em />We need to isolate the variable by the multiplication property of equality.
<em>x=36</em>.

As a result, the "secret number" is 36
