The answer is 12. Matthew would be 12 & Elizabeth would be 7. 12+7=19. So C is your answer.

The simplest way to do this would be to first subtract 5 from the total, because Matthew is going to be five years older than her.

19 - 5 = 14

14 will divide evenly by 2, making them each 7, but since Matthew is 5 years older, and 5 back to 7 to get his age.

7 + 5 = 12.

Matthew is 12 and Elizabeth is 7. Check your work.

12 + 7 = 19

A 25 - foot ladder is leaned against a wall. If the base of the ladder is 7 ft from the wall,
Fiesta28 [93]

Answer:

24

Step-by-step explanation:

Since the ladder, wall, and ground form a right triangle, you can use this formula:

A squared + B squared = C squared

A = 7 feet

C = 25 feet

B = distance the ladder will reach

49 + B squared = 625

B squared = 625 - 49

B = square root of 576

B = 24 feet

Step-by-step explanation:

The common difference d = -5.5.

The first term is given as 7.5.

Explicit formula is

an = a1 + (n - 1)d

= 7.5 + (n - 1)-5.5

= 7.5 - 5.5(n - 1)
