A)The variable y in the second equation has a coefficient of one so there will be fewer steps to the solution.

I just took the quiz on edge

Good luck!

We can solve for x in by substituting 'y=15-5x' from the second one into the first equation, because in the second equation, y has no coefficient, which will make it easier to substitute.

Question

Cerrena [4.2K]

Answer:C(x) = 2000+ 0.05 x

Step-by-step explanation: Cost (C) = fixed cost + (cost per pencil x number of pencils)

Since:

Fixed cost: $2000

Cost per pencil : $0.05

Replacing with the values given:

C(x) = 2000+ 0.05 x

Where x is the number of pencils manufactured.

the area of a square garden is 267 ft^2 what is the side length of each side? round your answer to the nearest hundredth place.

aksik [14]

Answer:

Side Length=16.34 ft
No

Step-by-step explanation:

The area of the square garden= $267$ ft^2$

Area of a Square of Side length s $=s^2$

Therefore:

$s^2=267$ ft^2\\$Take the square root of both sides\\s=\sqrt{267} \\$Side Lenght, s=16.34 ft (to the nearest hundredth place)$

Perimeter

Perimeter of a Square of Side length s=4s

Therefore, the perimeter of the garden =4*16.34=65.36 ft

Since 65 ft < 65.36 ft

Therefore, if you had 65 ft of fencing, it will not be enough to go around and cover the garden.
