Karleigh walks 5/8 mile to school every day . How far does she walk to school in 5 days
ziro4ka [17]

Hello, thanks for using Brainly!

First, our equation is: 5/8 x 5 = 25/8.

Our first step is to simplify.

When you simplify you get 3 1/8.

This is another way you can get it: (Multiply across. )

Number of the miles = \frac{5}{8} 5 = \frac{25}{8} = 3\frac{1}{8}

Enjoy your day.

PLEASE HELP ME SOLVE THIS Find all x-values for which f ( x ) = 2 for the function below.
alisha [4.7K]

Answer:

<h3>x = -3</h3>

Step-by-step explanation:

First let us get the equation of the coordinates

y-y0 = m(x-x0)

Using the coordinates ( - 3, 2 ), ( - 1, 0 )

m = 0-2/-1-(-3)

m = -2/2

m = -1

Substitute m = -1 and (-1, 0) into the formula

y - 0 = -1(x+1)

y = -x-1

f(x) = -x-1

Since f(x) = 2

2 = -x-1

-x = 2+1

-x = 3

x = -3

Hence the value of x is -3
