Answer:

x = 46°

Step-by-step explanation:

The sum of interior angles = (n-2) × 180°

= (5-2) × 180°

= 540°

2x+3x+3x-4+3x+x-8 = 540°

12x = 552°

x = 46°

Darrin is hanging 200 feet of Christmas garland on the fencing that encloses his rectangular front yard. The length is 5 feet le
frutty [35]

Answer:

Width = 17.5 feet,

Length = 82.5 feet.

Step-by-step explanation:

We have been given that Darrin is hanging 200 feet of Christmas garland on the fencing that encloses his rectangular front yard. This means that perimeter of rectangular front yard is 200 feet.

We know that perimeter of rectangle is two times the sum of length and width of rectangle. We can represent this information in an equation as:

2(l+w)=200...(1)

We are also told that the length is 5 feet less than 5 times the width. We can represent this information in an equation as:

l=5w-5...(2)

Upon substituting equation (2) in equation (1), we will get:

2(5w-5+w)=200

2(6w-5)=200

12w-10=200

12w-10+10=200+10

12w=210

\frac{12w}{12}=\frac{210}{12}

w=17.5

Therefore, the width of rectangular front is 17.5 feet.

Upon substituting w=17.5 in equation (2), we will get:

l=5(17.5)-5

l=87.5-5

l=82.5

Therefore, the length of rectangular front is 82.5 feet.

Clara has 6x - 7 pairs of shoes while Daniel has 2x + 3 pairs of shoes. How many more pairs of shoes does Clara have than Daniel
ale4655 [162]

Step-by-step explanation:

This is a binomial subtraction problem.

(6x-7)-(2x+3)

Binomial subtraction problems require one to phrase the problem as addition by flipping the signs.

(6x-7)+(-2x-3)

Now we can simplify:

6x-7-2x-3

4x-7-3

4x-10

So the answer is 4x-10 more pairs of shoes than Daniel.

See if that works.

Hope this helps!

Machine J's equation would be 30x=y. To find out how many more candies Machine J packets, You would plug in 11 as x and you would get 330. 
For Machine K, you would just plug in 11 as x. Your answer is 286. 
Now you would subtract. 330-286=44.

Triss [41]

Answer:Some farmers, such as cash grain farmers or dairy farmers, have large, well-established markets. They can use existing organizations to perform the marketing function for them, or they can band together, form a cooperative, and market their products jointly. Small-scale fruit and vegetable growers generally have more difficulty finding established markets; therefore, they usually develop marketing systems tailored to their unique situations.

Major Markets

Fruits and vegetables are produced seasonally, but the market requires products throughout the ye
