Danny is installing a fence around his rectangular yard. his yard is 20 feet long by 45 feet wide. if the fencing he picked out costs $25 per foot, how much money will danny spend on the fence?

Hey there!!

Basic formula :

Perimeter = 2 ( length + breadth )

Length = 20 ft

Breadth = 45 ft

2 ( 20 + 45 )

2 ( 65 )

= 130 ft

Given :

1 ft = $25

130 ft = 25 × 130

= $3250

The required answer is $3250 Hope my answer helps!

We need to find the total perimeter first by adding all sides:

20 + 20 + 45 + 45 = 130 feet

Then we need to cross multiply to find the cost:

If 1 foot = 25 $
130 feet = X $

130 * 25 = 3250$ total

Hope this is clear and helpful

5) (2,-1)  

Step-by-step explanation:

I believe you are just solving to make the equations true. so. for 5 just set the equation equal to each other.

5) 4x-9 = x-3

        +9      +9             - reminder do the inverse with these equations

                  6            - the 9 cancels out

4x=x +6                bring equation down

-x   -x                            - combine like terms + inverse

3x=6

/3       /3                 - divide both sides by 3

x=2

Next plug in,

4(2)-9=-1

2-3=-1

Therefore (2,-1) Is the answer where x=2 and y=-1

Answers for the rest are below!!

6) (6,-7) X=6  Y=-7

7) (0,-5)  X=0 Y=-5

8) (7,-1) X=7 Y=-1

There you go kiddo

if you need extra help make a comment and i will explain!
