Answer:

35.2

Step-by-step explanation:

<u>Find the missing angle:</u>

m∠L = 180° - 60° - 45° = 75°

<u>Use the law of sines to determine the lengths of the sides:</u>

LM / sin ∠K = KM / sin 75°
12 / sin 60° = KM / sin 75
KM = 12 sin 75° /sin 60° = 13.4 (rounded)
KL / sin ∠M = LM / sin ∠K
KL / sin 45° = 12 / sin 60°
KL = 12 sin 45° / sin 60° = 9.8 (rounded)

<u>Find perimeter:</u>

P = 12 + 13.4 + 9.8 = 35.2

What is the slope-intercept form of the equation 2x + y = 4?

Goryan [66]

<h3>Answer:</h3>

slope intercept form: y = -2x + 4

<h3>Explanation:</h3>

$\sf slope \ intercept \ form: y = mx + b$

where m is slope, b is y-intercept

=============================

$\rightarrow \sf 2x + y = 4$

$\rightarrow \sf y = 4-2x$

$\rightarrow \sf y = -2x +4$

Now, identify slope: -2, y-intercept: 4

If 5 sips +4 gulps = 1 glass and 13 sips +7 gulps = 2 glasses, how many sips equal a gulp?

nataly862011 [7]

Answer:

3 sips equal a gulp

Step-by-step explanation:

we have

$5sips+4gulps=1glass$ ----> equation A

$13sips+7gulps=2glass$

Divide by 2 both sides

$6.5sips+3.5gulps=1glass$ ----> equation B

equate equation A and equation B

$5sips+4gulps=6.5sips+3.5gulps$

Group terms that contain the same variable

$4gulps-3.5gulps=6.5sips-5sips$

$0.5gulps=1.5sips$

$gulps=(1.5/0.5)sips$

$gulps=3sips$

therefore

3 sips equal a gulp

What is the solution to the system of equations below? y=2/5x-3 and x = –10

Andru [333]

The solution to the system of equations $y=\frac{2}{5}x-3\,\,and\,\,x=-10$ is (-10,-7)

Option 1 is correct.

Step-by-step explanation:

We need to find the solution to the system of equations below.

$y=\frac{2}{5}x-3\,\,and\,\,x=-10$

The value of x i s x=-10

Putting value of x in first equation we can find value of y

$y=\frac{2}{5}x-3\\y=\frac{2}{5}*-10-3\\y=2*-2-3\\y=-4-3\\y=-7$

So, value of y is y=-7

The solution to the system of equations $y=\frac{2}{5}x-3\,\,and\,\,x=-10$ is (-10,-7)

Option 1 is correct.

C.) 4. Solve the system of equations

raketka [301]

You can set them equal to each other so -3x+4=4x-10 and then you add 3x and 10 on both sides and get7x=14 and then divided both sides by 7 and get x = 2 and check by plugging in and you get -2 for y on both so solution is x=2
