The submarine is at a depth of -116 2/7 feet when the scientists detect a signal frequency from the ocean floor. They dive farth

Lady_Fox [76]

Answer: $-64\frac{2}{7}\text{ feet}$

Step-by-step explanation:

When the scientists detect a signal frequency from the ocean floor, then the depth of submarine = $-116\frac{2}{7}$ feet

= $-\frac{814}{7}$ feet

When they dive farther to check the signal, then the depth of the submarine= $-180\frac{4}{7}=-\frac{1264}{7}$ feet.

The net change in their elevation = $-\frac{1264}{7}-(-\frac{814}{7})$

$=-\frac{1264}{7}+\frac{814}{7}\\=-\frac{450}{7}=-64\frac{2}{7}\text{ feet}$

One number is three less than a second number. Six times the first is 6 more than 3 times the second. Find the numbers.

Karolina [17]

Step-by-step explanation:

Given,

x = y - 3

Also,

6(y - 3) = 3y + 6

6y - 18 = 3y + 6

6y - 3y = 6 + 18

3y = 24

y = 24/3

y = 8

x = 8 - 3

x = 5

Therefore, the first number is 5 and the second number is 8.
