Chickens have 1 head and 2 legs
rabbits had 1 head and 4 legs
total heads is 30
c+r=30
total legs is 98
2c+4r=98
divide by 2
c+2r=49
multiply top equation by -1 and add to 2nd equation
-c-r=-30
<u>c+2r=49 +</u>
0c+1r=19
r=19
sub back
c+r=30
c+19=30
minus 19
c=11
11 chickens
19 rabbits

Answer:
$3523.44
Step-by-step explanation:
5000 = X × e^(3.5/100)(10)
X = 5000 ÷ e^0.35
X = 3523.440449
5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4
