Answer:Objective: Solve systems of equations with three variables using addition/elimination.
Solving systems of equations with 3 variables is very similar to how we solve systems with two variables. When we had two variables we reduced the system down
to one with only one variable (by substitution or addition). With three variables
we will reduce the system down to one with two variables (usually by addition),
which we can then solve by either addition or substitution.
To reduce from three variables down to two it is very important to keep the work
organized. We will use addition with two equations to eliminate one variable.
This new equation we will call (A). Then we will use a different pair of equations
and use addition to eliminate the same variable. This second new equation we
will call (B). Once we have done this we will have two equations (A) and (B)
with the same two variables that we can solve u

Answer:
The price depends on the day in whivh business is faster I see. So take for instance Saturday and Sunday. More people are free on the weekend so they would raise prices when more people come along on the weekend.
Answer:
x^2 - 10x + 29
Step-by-step explanation:
f(g(x)) = (x-5)^2 + 4
= x^2 - 10x + 25 + 4
= x^2 - 10x + 29
Volume= area of base x height
base= 3.14 x 4^2(8/2=4 for the radius)
base=50.24
base x height=50.24 x 23=1155.52, or 1156 ft3
