 what is 5/8y=4 3/4 and -5 3/4 +x=(-3 1/2)

 

 

What is 2/3 divided by 14 

 

 Daniel filled the gas tank in his car with 18.2 gallons of gas he drove 373.7 miles before filling his gas again. Daniel wants to build an equation to figure out the miles per gallon

1) Simplify \(4\dfrac{3}{4}\)   to  \(\dfrac{19}{4}\), and we have our equation  \(\dfrac{5}{8}y = \dfrac{19}{4}\). By multiplying both sides by  \(\dfrac{8}{5}\), we have \(y = \dfrac{38}{5}\)

 

Simplify \(-5\dfrac{3}{4}\) to \(-\dfrac{23}{4}\) and \(-3\dfrac{1}{2}\) to \(-\dfrac{7}{2}\), and we have our equation \(-\dfrac{23}{4} + x = -\dfrac{7}{2}\).  By adding \(\dfrac{23}{4}\) to both sides, we have \(x = \dfrac{9}{4}\) or \(x = 2\dfrac{1}{4}\). (\(-\dfrac{7}{2}\) --> \(-\dfrac{14}{4}\), \(\dfrac{-14 + 23}{4} = \dfrac{9}{4}\))

 

Hope this helps,

2) 2/3 divided by 14 is basically\(\dfrac{\dfrac{2}{3}}{14}\). If we multiply the numerator and denominator by \(\dfrac{\dfrac{1}{14}}{\dfrac{1}{14}}\), we have \(\dfrac{2}{3} \cdot \dfrac{1}{14} = \dfrac{1}{21}\)
