Belle is going to make chili for a football party. It will take 1 hour and 10 minutes to prepare all the ingredients and assembl

MrRa [10]

Answer:

1:10pm

Step-by-step explanation:

1st, you add all the time needed to make the chili & cook it.

1 hour + 10 minutes + 1 hour + 40 minutes = 2 hours & 50 minutes.

Now you work backwards from 4:00pm.

You go back 2 hours & you would be at 2:00pm

Now you go back another 50 minutes & you would be at 1:10pm

To double check, you can add 2 hours & 50 minutes to 1:10pm & you would get 4:00pm

If three times a number added to 8 is divided by the number plus 7, the result is four thirds. Find the number.

Answer:

4/5

Step-by-step explanation:

The wording is ambiguous, as it often is when math expressions are described in English. We assume you intend ...

$\dfrac{3n+8}{n+7}=\dfrac{4}{3}\\\\3(3n+8)=4(n+7)\qquad\text{multiply by $3(n+7)$}\\\\9n+24=4n+28\qquad\text{eliminate parentheses}\\\\5n=4\qquad\text{subtract $4n+24$}\\\\\boxed{n=\dfrac{4}{5}}\qquad\text{divide by 5}$

The number is 4/5.
