At the mall, Leona bought a T-shirt and a book for a total of $23. The book cost $12. How much did the T-shirt cost? (a)What is the unknown information?
(b)Let x represent the unknown information. Write an addition equation that models the problem
(c)Solve the equation.
(d)Answer the question.

jml angle lkj & angle mj = lm

16.80 times .20= 3.36

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
