Answer: Divide the sale price by the percentage amount that was paid.

Step-by-step explanation:

If a book is on sale for $6.30 with a 30% discount it means that you paid 70% of the original cost. In order to determine what the original cost was you can divide the sale price by the percentage that was paid:

$6.30 / .7 = $9.00, which is the original price of the book.

You can then double check your work - $9 x 70% = $6.30.

The time take for the cyclist to travel from Fort Worth to Fresno is $90 \ hours$

Explanation:

It is given that the distance from Fort Worth to Fresno is 1,530 miles.

The average speed of the cyclist is 17 miles per hour.

The time travelled by the cyclist can be determined using the formula,

$Distance=Speed \times Time$

Substituting the value of distance and speed, we get,

$1530=17\times Time$

Dividing both sides by 17, we get,

$90 =Time$

Thus, the time take for the cyclist to travel from Fort Worth to Fresno is $90 \ hours$

The equation for line j can be written as y=2x + 8. Another like k is perpendicular to line j and passes through the point (6,-6

Semmy [17]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 8 ← is in slope- intercept form

with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{2}$ , thus

y = - $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (6, - 6) into the partial equation

- 6 = - 3 + c ⇒ c = - 6 + 3 = - 3

y = - $\frac{1}{2}$ x - 3 ← equation of line k
