The sum of angles in a triangle is always equal to  180 degrees

Add:

65 + 51 + x + 73 = 180

x + 189 = 180

x = -9      That is fine that x is "-9" because this would just mean that the angle "x+73" is just bigger than it is supposed to be.

Proof:

65 + 51 - 9 + 73 = 180

Therefore, x = -9

Answer:

x = -9

Step-by-step explanation:

Notes to remember:

A triangle's angles will always add up to 180°

--------------------------------------------------------------------

As the image shows, we have two labeled angles. A 51° angle and a 65° angle.

Here's how you want to set up your equation:

180° = 51 + 65 + x + 73

(Rearrange)

180° = 51 + 65 + 73 + x

Add 51, 65, and 73

180° = 189 + x

Subtract 189 from both sides, to isolate x.

-9° = x

ALWAYS PLUG IN (the number that comes from the variable) TO CHECK YOUR WORK!

180° = 51 + 65 - 9 + 73

Answer:

35.375

Step-by-step explanation:​​

Add −1.5 and 9.5 to get 8.

Multiply 0.4 and 18 to get 7.2.

Expand  −0.2/7.2 ≈−36 by multiplying both numerator and the denominator by 10.

Divide 72 by −2 to get −36.

Convert 36 to fraction 8/288=36.

Subtract 288 from 5 to get −283.

-283/8 =35.375

Answers

Answer:

To factor out -1/3 out of the expression -1/3x - 8, first divide -8 by -1/3 to get 24. Now just put 24 in the place of -8 in the original expression. Your final answer should be -1/3(x + 24). Hope this helps and have a phenomenal day!

The height of a stack of DVD cases is in a proportional relationship to the number of cases in the stack. A stack of 7 cases and its height are shown. Find the constant of proportionality. Then use the constant of proportionality to find the height of a stack of 12 cases.

Answers

Answer:

For a stack of 12 DVD cases, it will be 132mm in height

Step-by-step explanation:

There are 7 cases stacked on top of each other and the total height is 77mm.

Since you must find the height of each individual DVD case you have to divide the height (77mm) by the number of DVD cases (7):

77 / 7 = 11        or       77 ÷ 7 = 11

Then, it asks to find the height of a stack of 12 cases, so take the 11, the height of each DVD case, and multiply it by 12:

11 × 12 = 132

So, the height of 12 DVD cases stacked on top of each other is 132mm.

The regular price of a pair of shorts was $58. During a sale, the price was reduced to
$43.50. Determine the percent discount. How would you do this? I know how to do it when it gives you the price before the discount and then it gives you the discount. But I was never taught how to do it this way.

Answers

DISCOUNT PERCENT = (MP - SP)×100%/MP

= (58-43.50)×100%/ 58

= 14.5×100%/58

=25%

answer: 25%
Steps: 58 - 43.50 = 14.5 (amount decreased)
(14.50/58) x 100 = 25%

5 + -2= 3

Step-by-step explanation:

the answer is 3 because you have to make zero pairs. the 2 negatives and 2 of the positives make a zero pair, which makes 3 positive ones left so the final answer is 3

5 + -2 = 3.
Three is the sum because 5 is the highest number & is a positive. Therefore you keep the positive & subtract as normal. Making the answer 3.

Step-by-step explanation:

Do 0.4 x 3.5 first, that gives you 1.4, then divide that by 0.5, which is 2.8.

If 0.4 times 3.5 equals 1.4 (0.4 x 3.5 = 1.4)
Then 1.4 divided by 0.5 equals 2.8 (1.4 divided by 0.5 = 2.8)
Then the missing number in the sentence is 2.8 (0.4 x 3.5 = 0.5 x 2.8)

Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run? Explain

Answers

Answer:

6 miles

Step-by-step explanation:

A mile is 1760 yards; and hour is 3600 (=2x1800) seconds.

So a yard per second is roughly two miles per hour (actually 1800/1760 x2 miles per hour, so the error is about 40 in 1800 or less than 1 in 40, 2.5%) and three yards per second is about 6 miles per hour. Upper bound of the estimate would be 6 + 2.5% = 6+0.15 = 6.15 mph.

Cows usually eat only grass and other plants, but farmers had been feeding them a meat and bone mixture that made the cows plumper. But somehow, at least one batch of the mixture had become contaminated with what was then an unknown killer: a prion.By 1993, British farmers were reporting up to one thousand new cases of BSE a week. Governments all around the world reacted by increasing testing for the disease and not allowing any cows to be eaten if they were at risk of having the disease. As sheep can also get a prion disease called scrapie, they were tested as well. Farmers were angry that they were losing their livestock, and nobody knew how to protect cows and people from the disease.Consumers were also in a panic when they learned about BSE, and for a very good reason: prions are infectious. If you eat a prion from a "mad cow or sheep, you are at risk for developing a human version of BSE. The public felt betrayed that their governments had underreacted to the problem or covered it up.Eventually, in 1997, governments began to ban farmers from feeding their livestock high-risk meat and bone mixtures. With that ban, the epidemic quickly peaked, and by 2010 had largely disappeared. Over the years, half a million cows and two hundred people had been killed by prions.In the end, the BSE epidemic was a watershed moment, or turning point, in public health. Citizens were enraged at their governments for having kept prions a secret. Governments, who had lost the public trust, struggled to find the best way to communicate health risks without creating unnecessary panic.How does the author's use of chronology help support the idea that the BSE epidemic was a watershed moment, or turning point, in government use of law to support public health?A.The author lays out a timeline to show how scientific discoveries made governments less likely to make laws for public health.B.The author makes it clear that prions were always known to be dangerous and that scientists discovered them to be the cause of mad cow disease.C.The author discusses how the mad cow disease epidemic ended only about twenty-five years after it first became a problem.D.The author shows how frustrated people were that nothing was done about a disease until over ten years after it was discovered.
