it confuses me when i have to fill in the in between i just dont quite understand how to work it out please explain it clearly
prisoha [69]

<em>Make the unknown numerator be x and unkown denominotor be y</em>

<em>We have :  7 - </em>\frac{x}{y} = 6\frac{4}{5}

            =>       \frac{x}{y} = 7 - 6\frac{4}{5}

                       \frac{x}{y} = \frac{1}{5}

<em>So we need to fill in the box :</em> \frac{1}{5}

<em>If the answer is helpful, Brainliest please!</em>

The balloon uses 4.5 quarts of gas in 7 minutes. How many gallons will it use per hour?
antoniya [11.8K]

Answer:

≈9.64 gallons

Step-by-step explanation:

To solve, we can figure out how many quarts are in a minute and use that to figure out how many quarts are in an hour. Then, we can convert quarts to gallons.

4.5 quarts = 7 minutes

First, we can find how many quarts equal 1 minute. To do this, we can divide both sides by 7 because anything divided by itself equals 1

4.5/7 quarts = 1 minute

Next, we want to figure out how many quarts go into 60 minutes, or 1 hour. To do this, we can multiply both sides by 60 because 1 * 60 = 60

4.5 * 60 / 7 quarts = 60 minutes = 1 hour

We now know how many quarts are in an hour, so we can now convert quarts to gallons

4 quarts = 1 gallon

divide both sides by 4

1 quart = 1/4 gallons

To get from quarts to gallons, we can divide by 4, so we have

(4.5 * 60 / 7)/4 = 4.5 * 60 / 28

≈9.64 gallons

Simplify the expression by combining like terms. <br> 22+5m-4m+7n8
solniwko [45]

Answer:

Second Option, m+7n+30

Step-by-step explanation:

First I'd combine the m terms

22+5m-4m+7n-8

     5m-4m

        =1m

22+1m+7n+8

Now the numbers with no variable

22+1m+7n+8

22     +       8

      =30

<em><u>m+7n+30 </u></em>is our final answer
