ludmilkaskok [199]

Answer:

Part 1) \frac{1}{8}

Part 2) \frac{1}{9}

Step-by-step explanation:

we know that

The quotient of a fraction by a whole number is the same that multiply the fraction by the reciprocal of the whole number

so

\frac{\frac{a}{b}}{c}=(\frac{a}{b})(\frac{1}{c})

Part 1) 1/4 divided by 2

\frac{\frac{1}{4}}{2}=(\frac{1}{4})(\frac{1}{2})=\frac{1}{8}

Part 2) 2/3 divided by 6​

\frac{\frac{2}{3}}{6}=(\frac{2}{3})(\frac{1}{6})=\frac{2}{18}

Simplify

\frac{1}{9}

Isabel joins a service to download movies. She pays $2 per movie, but she gets the first 5 movies for free. How many movies, m,
konstantin123 [22]
To find the equation, identify the slope and the y-intercept.

The slope is the coefficient to the variable. When you see the word 'per', you know that 2 is the slope, as she is paying 2 dollars per movie. This, in mathematical terms, is represented as 2x. 

The y-intercept is the amount she starts off with. She gets 5 for free, so the y-intercept is +5. 

The equation is c = 2m+5.

To solve for c = 50, plug 50 in and subtract 5 from both sides:

45 = 2m

m = 22.5
