Percentage of cats
$\frac{# animals}{#cats} = \frac{100}{?}$
$\frac{35}{12}= \frac{100}{?} 
$
**cross multiply 12 and 100 which is 1200
**divide 35 into 1200
the answer is 34.3% when rounded

percentage of snakes
$\frac{# animals}{#snakes} = \frac{100}{?}$

What is the solution of the system of equations? y = –2x + 8 y = x – 4

12345 [234]

y = –2x + 8
y = x – 4

We can use substitution.
-2x+8 = x-4
3x=12
x=12/3
x=4

y = x – 4
y=4-4=0
y=0

Solution of the system x=4,y=0,
it can be written as (4,0).
