The equation for an inverse or indirect variation is y = k/x. Fill in those value to first solve for k:  100=k/-13. Multiply both sides by -13 to get that k = -1300. Now use that k and the x value of 5 to solve for y: y = -1300/5. Divide that out to get that y = -260

What is s?? <br> A 44° <br> B 35.3° <br> C. 37.9°<br> D. 22°
melisa1 [442]

Answer: Choice B) 35.3 degrees

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

Work Shown:

Apply the law of sines

sin(S)/s = sin(R)/r

sin(S)/16 = sin(120)/24

sin(S) = 16*sin(120)/24

sin(S) = 0.57735026918962

S = arcsin(0.57735026918962)

S = 35.2643896827542

S = 35.3

Make sure your calculator is in degree mode.

3x+30+x=10+2x+5x+2 <br> i need help fast
kupik [55]

Answer:

x=6

Step-by-step explanation:

Group Like Terms:

3x+x+30=10+2x+5x+2

Add similar elements 3x+x=4x:

4x+30=10+2x+5x+2

Add similar elements 2x+5x=7x:

4x+30=10+7x+2

Group like terms:

4x+30=7x+10+2

Add the numbers 10+2=12:

4x+30=7x+12

Subtract 30 from both sides:

4x+30-30=7x+12-30

Simplify:

4x=7x-18

Subtract 7x from both sides:

4x-7x=7x-18-7x

Simplify:

-3x=-18

Divide both sides by -3:

\frac{-3x}{-3} =\frac{-18}{-3}

Simplify:

x=6

Hence, the correct answer is 6
