Answer:
Step-by-step explanation:
Let's look at the first two, and hopefully you'll be able to figure the rest out:
1. Answer below
The problem asks us to solve for 
, so that means we need to get on one side of the equation by itself. To do so, we will need to divide both sides of the equation by 
:
2. Answer below
The problem asks us to solve for 
, so that means we need to get on one side of the equation by itself. To do so, we will need to add 
to both sides of equation:
Answer:
length x width x height = volume
5.5 x 2 = 11 x 3 = 33
33 ft.

Step-by-step explanation:
X=numbers of hammers
y=numbers of scewdrivers
f(x,y)= total cost in $
f(x,y)=11x+6.65y
f(4,7)=4(11)+6.65(7)=44+46.55=90.55
Sol: an expresion for the total cost of the tools is f(x,y)=11x+6.65 y;
x=number of hammers
y= number of scewdrivers.
The total cost is $90.55
