Translate the word problem below into an equation men bove, Lyle was a careful craftsman, but he wasn't very creative, For example, he only sold two types of
wooden benches stained and unstained. The unstained benches cost $20 each and the stained cost $32
each. If Lyle sold 21 benches last month (stained and unstained combined) and collected a total of $600,
how many unstained benches did he selle

Step-by-step explanation:

u and s are the number or unstained and stained benches sold, respectively.

Lyle sold 21 benches for $600

u + s = 21

s = 21-u

20u + 32s = 600

20u + 32(21-u) = 600

-12u = -72

u = 6

Lyle sold 6 unstained benches.

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

its   c, f, a
