Chance can wash the car in 2 hours, while Sandy can wash the same car in 4 hours. How many hours would it take for them to wash
aliya0001 [1]

Answer:  First Option is correct.

Step-by-step explanation:

Since we have given that

Number of hours Chance can wash the car = 2 hours

Number of hours Sandy can wash the car = 4 hours

Work done by Chance per hour is given by

\frac{1}{2}

Work done by Sandy per hour is given by

\frac{1}{4}

Work done by altogether per hour is given by

\frac{1}{2}+\frac{1}{4}\\\\=\frac{2+1}{4}\\\\=\frac{3}{4}

So, Number of hours they take if they together wash the car is given by

\frac{4}{3}

Hence, First Option is correct.

Why is isolating the y-variable to graph is important
dusya [7]

Answer:

It is the easiest way to graph an equation.

Step-by-step explanation:

Isolating the y variable is also slope-intercept form.

Slope intercept form is the easiest form to use when graphing.

y = mx + b

m is the slope, b is the y-intercept.

it makes it way easier to graph an equation when it is in slope intercept form.


I hope that helps! =)
