12x = 2,700
---- ---------
12 12
x = 225
They can make a total of 225 necklaces
The equation : y = -5x + 9
Assuming that is a square pyramid
that is the square base+4 triangles
that is
side^2+4(1/2bh)
where b=side=14in
and h=height=13in
surface area=14^2+4(1/2)(14)(13)
SA=196+(2)(182)
SA=196+364
SA=560 square inches
<span>First, the inequality needs to be solved. The first step is to subtract 8 from both sides of the inequality, leading to 5r < 55. Dividing 5 out from both sides, this will leave r < 11. Next, to form a set notation, the inequality is written in such form: {r | r < 11}.</span>
