3 ÷ 7.71 = 0.38910....
You could round to 0.4 or 0.39 , etc.
Answer:
The domain: all real numbers;
The range: 
Step-by-step explanation:
The graph of the function y=|x| opens up and has a vertex at (0,0). If the graph of an absolute value function opens up and has a vertex of (0, -3), then the function has an expression
y=|x|-3 (see attached diagram).
The domain of the parent function y=|x| is the set of all real numbers, then the domain of the function y=|x|-3 is the set of all real numbers too.
The range of the parent function y=|x| is
then the range of the function y=|x|-3 is 
Answer:
a) 37.33 tons
b) 96 tons
c) Week 2
Step-by-step explanation:
a) 40+40+32=112÷3=37.33 tons
b) 32+40+24=96 tons
c) Week 2
Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)
