Answer:y=24 and x=10
Step-by-step explanation:
To find the value of x and y in x=3x-20 and y=-6+30
We gets
y=24
To get x
x=3x-20
Collect like terms
x-3x=-20
Divide through by -2
-2x=-20
x=10

Answer: m = -3

Well every time it gets rid of a shell it grows 1 1/3 times larger. So so to see how much it grows after the first time you say
1 cm * 1 1/3 = 1 1/3 cm
to get the next one you do the same
1 1/3 cm * 1 1/3 cm = 16/9
It will keep going multiplying by 1 1/3. So so we can say in an equation that the
(initial size) * 1 1/3 *(number of shells) = length
Or 1cm * 1 1/3 * n = L
We we know the final length is 10cm
So 1 1/3 * n = 10cm
n = 7.5shells
so approximately 7 or 8 shells
