Step-by-step explanation:

It's hard to see your photo but if that say m∠T than your answer would be

m∠ L.

The drawings are saying the the triangles are congruent which means all the interior angles of one triangle are congruent to the angles of the second triangle. m∠M = m∠J, m∠K = m∠E and m∠L = m∠T

Since you have two of the angles, you can also determine what m∠L and m∠T is equal to. The sum on all interior angles must be 180 degrees.

180 - 86 - 32 = 62

Angle L is the what you should put for your answer

Find the discount on a leather recliner with a regular price of $240 if the recliner is 10% off. What is the sale price of the recliner?
The discount on the leather recliner is $___

Answers

Answer:

Sale price = $216, Discount = 24$

Step-by-step explanation:

100%-10%=90%

240 x .90 = $216 (sale price)

240-216 = $24 off

Use the point-slope formula to write an equation of the line that passes through (-5, -4) and (3, -1).
Write the answer in slope-intercept form (if possible).

Answers

Answer:

point slope form: y + 4 = 3/8 (x + 5) slope intercept: y = 3/8x - 17/8

Step-by-step explanation:

y2 - y1 / x2 - x1

-1 - (-4) / 3 - (-5)

slope = 3/8

y + 4 = 3/8 (x + 5)

y = 3/8x + b

-1 = 3/8(3) + b

-1 = 9/8 + b

-17/8

y = 3/8x - 17/8

Find the value of x.

Answers

So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:

[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]

And now just solve for x!

[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]

So, your answer is:

x = -2.4

Answers

Answer:

PARALLEL

Step-by-step explanation:

The second equation, y = (1/3)x - 4, has already been solved for y. To compare the slopes easily, we need now to solve the first equation for y, obtaining y = (1/3)x - 4.

We see that these two lines have the same slope, m = 1/3, and thus conclude that these lines are PARALLEL.

On Monday, Ken spent half of his money on
a new game. The next day he earned
$12 mowing lawns. He now has $32. How much money did Ken have before he
bought the game?

Answers

Answer:

$40

Step-by-step explanation:

2(32-12)=40

hope this helps

X = his money
Y = half of his money
X = 2Y & Y = 1/2X

He earned $12 mowing lawn, and that, added to the other half of his money gives $32

As an equation, 32 = Y + 12
So Y = 32 - 12 if we takeaway 12 from both sides.
Therefore, Y = 20 and since X = 2Y, X = 2 x 20 which gives 40
Ken initially had $40

If 5x - 2y = 6 and 3x + 2y = 10, then find the value of x and y.

Answers

Step-by-step explanation:

[tex]\textsf{\large{\underline{Solution}:}}[/tex]

Given Equations:

→ 5x - 2y = 6 ----- (i)

→ 3x + 2y = 10 ---- (ii)

Adding (i) and (ii), we get:

→ 8x = 16

→ x = 16/8

→ x = 2

Substituting the value of x in (i), we get:

→ 5 × 2 - 2y = 6

→ -2y = 6 - 10

→ -2y = -4

→ y = -4/-2

→ y = 2

Therefore:

→ (x, y) = (2, 2) (Answer)

[tex]\textsf{\large{\underline{Verification}:}}[/tex]

Put x = 2 and y = 2 in first equation, the LHS becomes:

= 5 × 2 - 2 × 2

= 10 - 4

= 6

= RHS

Put x = 2 and y = 2 in second equation, the LHS becomes:

= 3 × 2 + 2 × 2

= 6 + 4

= 10

= RHS

Hence, our answer is correct (Verified)

Answer:

X= 2

Y= 2

(Include line numbers with your answer) Question 16Item 16(The passage below is a draft.)(1) In September 2018, an amazing spectacle took place in the skies above Olympic National Park: blindfolded, sedated mountain goats hovered in the air, suspended in harnesses from a helicopter. (2) After the helicopter set the goats down, veterinarians examined and tagged them. (3) A truck then transported the goats 180 miles away to North Cascades National Park. (4) Once there, helicopters again lifted the goats, this time in crates, into the mountains to be set free. (5) In this way, wildlife officials caught 114 goats in the first phase of the Mountain Goat Management Plan, but they ultimately will have relocated 90 percent of the 700 goats from the Olympics to the North Cascades. (6) This removal process may be complicated, but it is necessary.(7) Park officials cited several reasons why the goats had to go. (8) First, goats are not indigenous to the region; the area began to be advertised as a vacation destination in the early twentieth century. (9) Since then, the goat population has flourished and could reach 1,500 by 2028. (10) Park officials also worry about the goats deleterious habits of damaging vegetation and causing erosion. (11) In the 1980s, a brief attempt to relocate the goats was met with public outcry.(12) However, safety concerns were the most pressing reason for the goats removal. (13) With few salt licks in the Olympics, the goats turn to another source: humans. (14) Salt in human sweat is a goat magnet; worse still, some thoughtless and irresponsible people feed the goats directly. (15) Once accustomed to people, goats become aggressive in their pursuit of food. (16) After a goat injured a hiker in 2010, officials began formulating plans for the goats removal.(17) The North Cascades were the ideal spot to resettle the goats. (18) As goats are native to the region, the habitat is better suited to their grazing habits. (19) Resettled in the remote parts of the park, where salt licks are plentiful and hikers are scarce, the goats will likely regain their natural wariness of people. (20) Additionally, an influx of goats to the park will boost the decreasing native population and introduce more genetic diversity.The writer is considering deleting the underlined text in sentence 14 (reproduced below).Salt in human sweat is a goat magnet; worse still, some thoughtless and irresponsible people feed the goats directly.Should the writer keep or delete the underlined text?Keep it, because it makes the argument more persuasive by including language that increases the emotional engagement of the audience.Answer A: Keep it, because it makes the argument more persuasive by including language that increases the emotional engagement of the audience.AKeep it, because it clarifies the point the writer is making by explaining which people are at the greatest risk of being hurt by the goats.Answer B: Keep it, because it clarifies the point the writer is making by explaining which people are at the greatest risk of being hurt by the goats.BKeep it, because it encourages the audience to identify with the park officials who work to solve the problem rather than the park visitors who make the problem worse.Answer C: Keep it, because it encourages the audience to identify with the park officials who work to solve the problem rather than the park visitors who make the problem worse.CDelete it, because it distracts from the writers purpose of emphasizing human safety concerns by using language that focuses blame on human visitors to the park.Answer D: Delete it, because it distracts from the writers purpose of emphasizing human safety concerns by using language that focuses blame on human visitors to the park.DDelete it, because it contradicts the writers claim in sentence 15 that goats behave differently after they are accustomed to human contact.
