(2x+y=-2
5x + 3y = -8
Solve by elimination
Answer:
y = -6, x =2
Step-by-step explanation:
To solve by elimination, you have to line both equations up together. Then, you multiply both equations until one variable is removed.
2x+y = -2
5x + 3y = - 8
There are many different ways to solve an elimination problem, but generally you should look for the simplest route. Here, I would multiply the top equation by -3.
-6x -3y = 6
5x +3y = -8
Imagine you are adding the two equations together. You end up with
-x = -2
Then solve for x. In this situation, it is fairly simple. Take out a factor of -1.
x = 2
Finally, choose one of your beginning equations and plug your new-found x value back into the equation.
2(2) +y = -2
4 + y = -2
y = -6
b. Find the value of x below:
Answer: 5
Step-by-step explanation: it is a supplementary angle so it has to add up to 80
Answer:
5
Step-by-step explanation:
line = 180
therefore 15x + 5 + 100= 180
15x + 105 = 180
15x = 180 - 105
15x = 75
x = 75/15
x = 5

5280 ft. = 1 mile
So....
26 x 5280 = 137,280
two distance are in the ratio 9 to 4 if the first distance is 270km, what is the second distance?
Let's practice a little algebra and set the second distance to x.
9/4=270/x
solve
9x=270*4
x=30*4
x=120
The second distance is 120.
Done! any question about this just ask me in the comment.

Lyle was a careful craftsman, but he wasn't very creative, For example, he only sold two types of
wooden benches stained and unstained. The unstained benches cost $20 each and the stained cost $32
each. If Lyle sold 21 benches last month (stained and unstained combined) and collected a total of $600,
how many unstained benches did he selle
Answer:
Step-by-step explanation:
u and s are the number or unstained and stained benches sold, respectively.
Lyle sold 21 benches for $600
u + s = 21
s = 21-u
20u + 32s = 600
20u + 32(21-u) = 600
-12u = -72
u = 6
Lyle sold 6 unstained benches.

You are thinking of opening a small copy shop. It costs $5000 to rent a copier for a year, and it costs $0.03 per copy to operate the copier. Other fixed costs of running the store will amount to $400 per month. You plan to charge an average of $0.10 per copy, and the store will be open 365 days per year. Each copier can make up to 100,000 copies per year.
Required:
a. For one to five copiers rented and daily demands of 500, 1000, 1500, and 2000 copies per day, find annual profit. That is, find annual profit for each of these combinations of copiers rented and daily demand.
b. If you rent three copiers, what daily demand for copies will allow you to break even?
c. Graph profit as a function of the number of copiers for a daily demand of 500 copies; for a daily demand of 2000 copies. Interpret your graphs.
Answer and explanation:
A. To calculate annual profit, we find:
Total income - total cost for the 365 days in a year
Total income for different daily demands:
For 500 copies= 500×365×0.10=$18250
For 1000 copies= 1000×365×0.10=$36500
For 1500 copies=1500×365×0.10=$54750
For 2000 copies=2000×365×0.10=$73000
Total cost using five copiers= 400×12+5000×5+500000×0.03= $44800
Total cost using four copiers=
400×12+5000×5+400000×0.03=
$36800
Annual profit with daily demand of 2000 and five copiers available= $73000-$44800= $28200

What type of construction is illustrated in the diagram below
Answer:
This is an angle bisector.
Step-by-step explanation:
This is due to the arcs being drawn from point C in a manner to intersect the line segment AB, and the points are then used to find another point by creating arcs, thus creating the angle bisector for the angle ∠ACB.
