Franco read 3/8 of a chapter of his history book in 1/5 of an hour. at this rate, how many chapters of his history book can he read in 1 hour?

He can read chapters of his history book in 1 hour.

Explanation

Franco read 3/8 of a chapter of his history book in 1/5 of an hour.

Suppose, he can read chapters of his book in 1 hour at this rate.

So, the equation according to the ratio of 'the chapter to the time' will be....

So, he can read chapters of his history book in 1 hour.

it is x equals 3   plese mark me really need it

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
