I can help you with the first two problems. Since it's what I've recently studied.
19. Angles 3 and 4 (they are corresponding and alternative interior) are congruent with angle 6.
20. Angles 2 and 5 (corresponding and alternative interior) are congruent with 6.

Answer:

x = the first mystery number = 2

y = the second mystery number = 0.8

Step-by-step explanation:

Let

x = the first mystery number

y = the second mystery number

8*x + 10*y = 24

8x + 10y = 24

7*x + 10*y = 26

7x + 10y = 26

8x + 10y = 24 (1)

7x + 10y = 26 (2)

Subtract (1) from (2) to eliminate y

8x - 7x = 26 - 24

x = 2

Substitute x = 2 into (1)

8x + 10y = 24 (1)

8(2) + 10y = 24

16 + 10y = 24

10y = 24 - 16

10y = 8

y = 8/10

y = 0.8

x = the first mystery number = 2

y = the second mystery number = 0.8

Greatest common factor 10b^2 and 4a^3

Reil [10]

The answer will be 2. the gcf of the equation is 2 because 2 goes into 10 by 5 and into 4 by 2 leaving you with 2(5b^2+2a^3).
