Answer:
The weight of 10 deer is 2,000 pounds
Step-by-step explanation:
Let
x ----> the weight of the elephant in pounds
y ----> the weight of the whale in pounds
z ----> the weight of the giraffe in pounds
w ----> the weight of the deer in pounds
step 1
Find the weight of the whale
we know that
[tex]x=12,000\ lb[/tex]
[tex]x=\frac{3}{4}y[/tex] ----> equation A
substitute the value of x
[tex]12,000=\frac{3}{4}y\\\\y=12,000(4)/3\\\\y=16,000\ lb[/tex]
step 2
Find the weight of the giraffe
[tex]z=\frac{1}{8}y[/tex]
substitute the value of y
[tex]z=\frac{1}{8}(16,000)\\\\z=2,000\ lb[/tex]
step 3
Find the weight of 10 deer
[tex]z=\frac{5}{6}(12w)[/tex]
simplify
[tex]z=10w[/tex]
that means
The weight of the giraffe is equal to the weight of 10 deer
therefore
The weight of 10 deer is 2,000 pounds
