Solve For X.Please I Need Help

Answers

Answer 1

Answer:

-11 is your answer.

Step-by-step explanation:

Total measurements of interior angles in a triangle = 180°.

Note that the red square located on the bottom right angle signifies that it is a right angle, with a measurement of 90°. Set the equation:

Total measurement = (90) + (70) + (x + 31)

180 = x + (90 + 70 + 31)

180 = x + 191

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 191 from both sides:

180 (-191) = x + 191 (-191)

180 - 191 = x

x = - 11

please HELP MEEEEEE .A store owner wants to make a candy that sells for $1 per pound.he has 50 lb of sugar candies that cost $1.20 per pound.how many pounds of gummy candies that cost 80 cents per pound should he add.

Answers

Answer:

50 pounds

Step-by-step explanation:

we can use the equation           60+80/100x=1(x+50)

we get 80/100 x because the gummy candies are 80 cents or 80/100x

we get 60 from multiplying 1.20$ x 50 = 60

                                                    solve:

                        60+80/100x  =  x+50

                           60 = x-80/100x+50

                             60-50 = 20/100x

                              10 = 20/100x

                               x= 10 x 100/20 = 10x5= 50 pounds

Using proportions, it is found that he should add 50 pounds of gummy candies that cost 80 cents per pound.

What is a proportion?

A proportion is a fraction of a total amount.

This problem is organized as follows:

There is a total of 50 + x pounds.Of those, 50 cost $1.2 per pound.x cost $0.8 per pound.The selling price is of $1.

Hence:

[tex]\frac{50}{50 + x}1.2 + \frac{x}{50+x}0.8 = 1[/tex]

[tex]\frac{60 + 0.8x}{50 + x} = 1[/tex]

[tex]50 + x = 60 + 0.8x[/tex]

[tex]0.2x = 10[/tex]

[tex]x = \frac{10}{0.2}[/tex]

[tex]x = 50[/tex]

He should add 50 pounds of gummy candies that cost 80 cents per pound.

If it snows 3 inches in 6 hours, how many inches will we have after the 36 hours of snowing from this snow storm?

Answer:

6 inches of snow

Step-by-step explanation:

6x6=36

snows 3 inches in 6 hours

i

Answer:

18

Step-by-step explanation:

3 inches for every 6 hours. There are 6 6-hour groups in 36, so to find the inches in 36 hours, we would multiply the 3 inches times the 6 groups of 6-hour increments (aka 3*6). 3*6 = 18, so after 36 hours of snowing, we'd end up with 18 inches of snow.

Boris rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 89 cents for each mile driven. Boris had to pay $131.76
when he returned the truck. For how many miles did he drive the truck?

Answers

Boris drove the truck 129 miles. You take how much the base fee (16.95) and subtract it from the total of how much he had to pay (131.79). The problem would look like $131.79 - $16.95 = $114.84. Then would would take 114.84 and divide it by the cost of one mile. This problem would look like $114.84 divided by $0.89 = 129. This means the driver drove 129 miles! I hope this helps!

What if it were a really special bird: one with beautiful feathers, an entrancing call, or a silly dance? What if seeing that one special bird would allow you to win a contest?If that contest doesn't get you on television or win you any cash prizes, would you still do it? For those who participate in the "Big Year," the honor of beating the previous record is the only reward they get or even want.A "Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region. For most in North America who participate in a "Big Year," this region is the lower 48 American states, plus Alaska, Canada, and a couple of French islands off the Canadian coast.You may be thinking that looking at birds is silly, but just think about the numbers of the recent record holders and the commitment it takes to get these numbers. One recent "Big Year" winner managed to see 744 birds in one year, missing the record by just one bird. Big Year birders travel by train, plane, boat, car, bicycle, and of course, by foot. They can cover over 150 thousand miles to get numbers of sightings this high. They can also spend a small fortune.Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contest is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating.You don't have to be able to travel a continent to have a big birding experience though. Have a big month. Or a big weekend. Set a personal record, learn to identify the species that live in your part of the world, or try to learn the calls of just two species of birds. You will soon find looking at birds isn't such a strange way to spend your time.Extra! Extra! Backyard BirdingMany schools, families, and young birders across the country participate in the "Great Backyard Bird Count." While not as long as a "Big Year," the "Great Backyard Bird Count" happens every year. It depends on birders and families across the country to watch feeders and other areas in their yards and count the number of birds they see. Unlike the "Big Year," the goal is not to see who can count the most birds. Instead, participants in this event work together to help bird experts get a good idea of how birds are doing. Participants are given checklists and enter their sightings on a website. Called a "citizen-science" project, this event is open to anyone, requires no travel, and happens every year over one weekend in February.Which of the following best states the main idea of the article "A Big Year"?A)"Big Year" birders compete for honor, love, and record-setting.B)"Big Year" birders get very competitive about seeing rare birds.C)"Big Year" birders have a list of important birds to see.D)"Big Year" birders compete to see more birds than others. is y=x^8 an exponential function who is the Prime Minister of the great "India" Which of the following relations is a function?O A{(-1, - 4), (-1,0), (- 1,5), (- 1, 7), (-1,9)B.{(-2, - 4), (-1,7), (1, - 1), (1, 1), (3,9)}C.{(-4,9), (- 3, 1), (- 2, 3), (- 2, 12), (0, 6) }D.{(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)} O Beth walked 10 7/8 miles one week. she walked 2 1/4 fewer miles the following week.
