8 0

Answer:

X = \frac{13}{16}

Step-by-step explanation:

2 (4-8x) + 6 = 1

Multiply parentheses by 2

8 - 16x + 6 = 1

add (8 + 6)

14 - 16x = 1

Move constant to right and change its sign

-16x = 1 -14

Calcualte te difference

-16x = -13

divide bot sides by -16

x = \frac{13}{16}

kvasek [131]

The fraction of the fence completed in one hour at a rate of  \frac{2}{5} of the

fence in  \frac{3}{4} hours is  \frac{8}{15}.

<h3>How can the fraction completed in one hour be found?</h3>

The fraction of the fence completed in \mathbf{\frac{3}{4}} of an hour = \frac{2}{5}

Required:

The fraction of the fence the student completes per hour;

Solution;

The time \mathbf{\frac{2}{5}} of the fence is completed =  \frac{3}{4} of an hour

Therefore;

The \ in \ \mathbf{\frac{\dfrac{3}{4} \ hour}{\dfrac{3}{4} \ hour}}  = 1 \ hour \ the \ frraction \ completed = \dfrac{\dfrac{2}{5} }{\dfrac{3}{4} \ hour}  = \dfrac{8}{15} \ per \ hour

The fraction of the fence completed per hour = \underline{\frac{8}{15}}
