a.  Equation:

3x + 21 = 6x - 60           {measure of corresponding angles is the same}

3x - 6x = -60 - 21

- 3x = - 81

b. Value of x:

  x = 27

c.  Ange measures:

3x + 21 = 3×27 + 21 = 81 + 21 = 102°

or:

6x - 60 = 6×27 - 60 = 162 - 60 = 102°

Step-by-step explanation:

Under a reflection in the y-axis

a point (x, y ) → (- x, y )

Hence

A'(-5, - 3 ) → A''(5, - 3 )

B'(4, 4 ) → B''(- 4, 4 )

C'(4, 2 ) → C''(- 4, 2 )

D'(- 2, - 1 ) → D''(2, - 1 )

Determine the mixed number that correctly adds 3/5, 5/8, and 15/32
Vitek1552 [10]

Answer:

The answer of the addition of 3/5, 5/8 and 15/32 is 1/2

Step-by-step explanation:

3/5 + 5/8 + 15/32

We find the LCm of the denominators, that is, 5, 8 and 32

LCM = 5*32 = 160

[(160/5 + 3) + (160/8 + 5) + (160/32 + 15)]/160

[(32+3) + (20+5) + (5+15)]/160

[35+25+20]/160

80/160 = 1/2

What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}?
Sophie [7]
Hi there! The answer is B.

5r \leqslant 6r - 8
Subtract 6r from both sides.

- r \leqslant  - 8
Divide both sides of the inequality by -1. Remember that dividing by a negative makes the sign flip.

r \geqslant 8
Therefore, the solution must be bigger than or equal to 8. From the given solution set, the answer is B. {8, 9, 10}

~ Hope this helps you!
