6. Carlos buys an envelope of mixed flower seeds. The envelope contains 55 seeds. Of the plants that sprout, 19 have yellow
flowers. About how many seeds would Carlos most likely need to
plant to get a total of 57 plants with yellow flowers?

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the radius is 2 times the diameter.
