First:

X = 15

Step-by-step explanation:

So the two angles are congruent, or they are the same angle. So you write the equation as 5x + 9 = 84.

5x + 9 = 84

      -9     -9

5x = 75

(divide) 5 from both sides

x = 15

Second:

X = 27

Step-by-step explanation:

For this one I <em>believe </em>the answer is X = 27 because both equations should equal 180 degrees.

So you write the final equation:

(x + 72) + (3x) = 180

     -72                -72

(combine X's):

4x = 108

Divide both sides by 4

X = 27

Third:

X = 40

Step-by-step explanation:

For this one, the angles match again, so you write it s:

4x - 50 = 2x + 30

    +50           +50

4x = 2x +80

-2x  -2x

2x = 80

Divide both sides by 2

X = 40

End

I super hope this helped!

Maybe brainliest? No pressure!

Let me know if this works or you need more help!

Set up a proportion.

The total side of the “top” line is 8 + 10 = 18. The total side of the “bottom” line is 45. This makes the ratio 18/45.

Now we are trying to find the “larger” bottom segment, let it be x. Because the lines are parallel, the ratio of the “larger” top and bottom segments is equal to the ratio of the whole top and bottom lines.

So 18/45 = 10/x

Reduce 2/5 = 10/x

Cross multiply 2x = 50

Solve x = 25

3. A soccer team played 160 games and won 65 percent of them. How many games did the team win?
Airida [17]

Answer:

b.) 104

Step-by-step explanation:

Percent formula:

x/y = p/100

where x is the fraction, y is the total, and p is the percent

This means:

x = number of games the team won

y = total number of games

p = percent the number of teams won

Let's plug these values into the equation:

x/y = p/100

x/160 = 65/100

Solve by cross-multiplying:

x/160 = 65/100

100(x) = 100x

160(65) = 10,400‬

100x = 10,400

/100     /100

x = 104

Therefore, the team won 104 games.

PLEASE HELP<br> Solve. x^2+9x+2=0
Nataliya [291]

Answer:

x = (1/2) (-9 ± √73)

Step-by-step explanation:

Using completing the square method

x²+9x+2=0

x²+9x = -2   (complete the square by adding (9/2)² to both sides)

x²+9x + (9/2)² = -2 + (9/2)²

( x + (9/2) )² = -2+ (9/2)²

( x + (9/2) )² = -2+ (81/4)

( x + (9/2) )² = 73/4

x + (9/2)  = ± √(73/4)

x + (9/2)  = ± √(73) / 2

x = -(9/2) ± √(73) / 2  (factorize out (1/2) )

x = (1/2) (-9 ± √73)
