2 3/4 quarts equals how many pints

mr Goodwill [35]

The answer to this question would be: 5 1/2 pints

A quart is a unit that used for volume. A quart would be equal to 2 pints or 1/4 of gallons. A quart is also roughly equal to 4 cups. In this question, you asked to convert quarts into pints. Then the calculation would be:

Quart = 2 pints
2 3/4 quart = 2 * (2 3/4 pints)= 4 6/4 pints = 5 2/4 pints= 5 1/2 pints

This is algebra 1 <br> (solve a system of equation using any method: word problems)

hodyreva [135]

Answer:

<em>Hence, it will take</em><em> 9 seconds </em><em>for kirk to run </em><em>63+9=72 yards </em><em>and catch upto Max. </em>

Step-by-step explanation:

Let 'y' represents the time Max and Kirk took to meet.

Let the distance between the destination where they will meet from the place where Max is be: x yards

So the distance of destination from initial position of kirk is x+9 yards ( As Max is given a head start of 9 yards)

As speed of Max is 7 yards per sec.

And $speed=\dfrac{distance}{time}$

Hence,

$7=\dfrac{x}{y}$

$7y=x\\\\-x+7y=0-------(1)$

also speed of kirk is 8 yards per second.

By the similar definition of speed we have:

$8=\dfrac{x+9}{y}\\\\8y=x+9\\\\-x+8y=9--------(2)$

Hence (1) and (2) are the required system of equation.

So on solving the system of equations by elimination method we have:

y=9 and x=63.

Hence, it will take 9 seconds for kirk to run 63+9=72 yards and catch upto Max.
