Toddisas seller. I have sold a gold ring for $ 78 and earned a 10% commission. How much commission did he earn?

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

3; 9 is 8 to -4

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
