A store has a 30 % sale on all items (x). For customers with a discount card, the store takes off an additional 10 % at the cash register. Write a price function S(x) that computes the final price of the item in terms of the original price x.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

$15 each

step-by-step explanation:

$45/3 children= $15 each

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
