x=shortest side length

x+x+6+2x-6=4x=48

x=12 second side=18 third side =18

2^10=1024

2+4+8+16+32+64+128+256+512=1022

1024-1022=2

x=3y/2 x=3z/5 z=15y/6=5y/2

y+3y/2+5y/2=10y/2=5y y=16

x=24 z=40

40+24+16=80

x=24

all of them so -1,9, and. -18 right?

1/4x+25=0

multiply by 4 gives x+100=0

subtract both sides by 100 gives x=100

its just a verticle line. find the point (0,-3) and go up and down

i don't know how to solve it but heres how to check. pretend x=1 and y=2. find the rate and use it in the second one you will probably see it is not equal to 2

z=zoe's money

l=luke's money

z-50=l+50

z=l+100

$\frac{2l+200}5=\frac{2l}3+12$

$6l+600=10l+180$

$4l=420$

$l=105$

so Luke had 105 dollars at first

r=$\frac2{2\pi}=\frac1\pi$

c=r^2=$\frac1{\pi^2}$

c/2=$\frac1{2\pi^2}$

oops your grammer was wrong so i got confused just multiply by 4 and you get $\frac2{\pi^2}$

volume of cone formula=$\pi r^2 \frac{h}3$

radius of cone=4/2=2

volume of cone=$8\pi$

volume of ice cream=$4\pi$

$8\pi>4\pi$

so the ice cream will not spill out of the cone if it melts
