Suzy is ten years older than Belly, and the next year she will be twice as old as Billy. How old are they now? Show solution.
Snezhnost [94]

Answer:

I understand there is a typo, so Belly and Billy are the same person. His age is represented as B, and Suzy's as S.

S = 19

B = 9

Step-by-step explanation:

Suzy is ten years older than Belly:

(1)  S = B + 10

the next year she will be twice as old as Billy

(2)  S + 1 = 2 (B + 1)

solving the system of equation (1) and (2):

Making (2) - (1):  

1 = 2 (B + 1) - B - 10 => 1 = 2 B + 2 - B - 10  => 1 = B - 8 => B = 9

replacing in (1) S = 19

The negative sign indicates a decrease.

The decrease in price is 37.5%.

swat32

Answer:

25 meters.

Step-by-step explanation:

Given in the question that,

Initial depth of the submarine = 8 meters

After the order of the captain, the submarine was made to dive another 17 meters.

So, the final cruising depth of the submarine can be calculated by <u>adding the initial depth of the submarine and the depth further increased upon the order of the captain</u>.

Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.
