19) 15/a = 3/2

Start by cross multiplying

3a = 30

Divide both sides 3

a = 10

21) 2/7 = 4/d

2d = 28

   d= 14

23) 8/p = 3/10

80 = 3p
p = 26.66

25) 2 / -5 = 6/t
  2t = -30

  t = -15

x = 5

Step-by-step explanation:

Alternate Interior Angels are Congruent.

14x - 2 = 12x + 8

Combine Like-terms.

2x = 10

Divide by x

x = 5

Answer from: heavendl13

x = ln y / ln 3.

Step-by-step explanation:

Finding the inverse means converting the equation to x = a function of y.

y = 0.3^x

Taking logs:

ln y = ln 0.3^x

By the laws of logs:

ln y = x ln 0.3

x = ln y / ln 3 is the inverse.

Answer from: smann211

According to external angle theorem, 112 = 58 + x. x =112-58 = 54. Now summation of all the angles of a triangle is 180°. Therefore, 58+y+54 =180. Y= 180 - 112 = 68. Therefore x= 54 and y= 68.

Answer from: ManBun99

For y try substracting 112 from 180 wich should give u 60 which is y now add 60 plus 58 which is 118 now substract 118 from 180 which is 62 aka x

Answer from: taniaorozco

y = -5 cos x is a basic (simple) variation of the basic trig function y = cos x.

The given y = -5 cos x could be re-written as y = -5 cos 1x.
Compare this to the most general form: y = a cos bx.

Here we see that the coefficient b equals 1.

There is a rule for finding the period of such a function: Period = 2pi/b.

Since b = 1 here, the Period here is 2pi/1, or simply 2pi.

Please stop saying "I'm terrible with math." That does not help you at all. Say, instead, "With just a little help I could understand this just fine."

Answer from: sana20

x = 5

Explanation:

The alternate interior angles are congruent because of the parallel lines.

Set the angle expressions equal to each other. Solve for x.

12x+8 = 14x-2

12x+8-12x = 14x-2-12x subtract 12x from both sides

8 = 2x-2

8+2 = 2x-2+2 ... add 2 to both sides

10 = 2x

2x = 10

2x/2 = 10/2 ... divide both sides by 2

x = 5

As a check, plug this x value back into the original equation. After simplifying, you should get the same number on both sides.

12*x+8 = 14*x - 2

12*5+8 = 14*5-2 ... plug in x = 5

60+8 = 70-2

68 = 68

Both angles shown are 68 degrees, so we have confirmed the answer.
