Let us say that:
x = weight of llamas
y = weight of okapi
From the problem, we can create the equations:
x + y = 450 -->
1
3 x = y + 190 -->
2
Rewriting equation 1:
x = 450 – y
From equation 2:
3 (450 – y) = y + 190
1350 – 3 y = y + 190
4 y = 1160
y = 290
From equation 1:
x = 450 – 290
x = 160
Therefore a llama weighs 160 kilograms while okapi weigh
290 kilograms on average.

7/8 is tricky to do on a computer, but I will say that it is 87.5 percent or 0.875.
Do you know how to do normal long division? This is like that. Just after the decimal point, drop a 0 down.
I hope this helps!
/THe value of 1 is 100 is related to the value of 900 in the second number.
-6q^2 + 4q^2 + 8q - 9a^2
Combine like terms:
-2q^2 + 8q - 9a^2
You cannot combine q^2 to q because they do not have the same number of exponents!
