For questions 13 – 15, find x so that q || r. State the converse used.
Grace [21]

Answer:

13. x = 7 ; Converse : Alternate interior angles are equal .

14.  x=12; Converse used : Linear pair

15.  x = 23; Converse: Corresponding angles are equal

Step-by-step explanation:

13.

Refer the attached figure

Given: q || r

\angle CBE =\angle DEB (Alternate interior angles )

So,  15x+3=108

15x=108-3

15x=105

x=\frac{105}{15}

x=7

So, x = 7 ; Converse : Alternate interior angles are equal .

14.

Refer the attached figure

Given q||r

\angle PQT = \angle STQ (Alternate interior angles

So,\angle PQT = \angle STQ=11x-28

Now\angle UTQ + \angle STQ = 180^{\circ}(Linear pair)

So,7x-8+11x-28=180

18x-36= 180

18x=216

x=\frac{216}{18}

x=12

So, x=12; Converse used : Linear pair

15.

Refer the attached figure

Given q||r

\angle BDC+\angle CDE = 90+2x

\angle BDE=\angle PBC(corresponding angles)

90+2x=5x+21

90-21=5x-2x

69=3x

23=x

So, x = 23; Converse: Corresponding angles are equal

PRETTY PLEASE HELP?????? 1. John can spend up to $40 for gasoline and a carwash at a service station. The carwash will cost $6.0
galina1969 [7]
1. 4.5g + 6 < = 40
    4.5g < = 40 - 6
    4.5g < = 34
    g < = 34/4.5
    g < = 7.56
True statement : John can buy 7 gallons but not 8

2. 250 + 3b < = 800
    3b < = 800 - 250
    3b < = 550
    b < = 550/3
    b < = 183.33
True statement : The maximum number of new baseballs that can be purchased is 183

3. 3x + 6 > 15
    3x > 15 - 6
    3x > 9
     x > 9/3
     x > 3

4. 4x - 6 < 2x + 8
    4x - 2x < 8 + 6
     2x < 14
      x < 14/2
      x < 7

5. 3 - 2x > 9
    -2x > 9 - 3
    -2x > 6 ...when dividing by a negative, u flip the inequality sign
      x < -6/2
      x < -3
     True statement : - 2

7. 3x - 3 < -12         OR     -4x < = -32
    3x < -12 + 3                    x > = -32/-4
    3x < - 9                           x > = 8
      x < -9/3
      x < -3
answer : x < - 3 OR x > = 8

8. -7x + 9 < 72    AND   5x - 3 < = 7
    -7x < 72 - 9                5x < = 7 + 3
    -7x < 63                     5x < = 10
     x > -63/7                     x < = 10/5
     x > - 9                         x < = 2
answer : -9 < x < = 2
