Mathematics

abruzzese [7]3 years ago

Answer:

-75 m

Step-by-step explanation:

Use sea level as the reference point.  

Initially the position is -50 m.

If the submarine goes up 15 m, then its new position is (-50 + 15) m, or -35 m.

If the sub now descends 40 m, its new position is (-35 - 40) m, or -75 m

Which method correctly solves the equation using the multiplication property of equality and the reciprocal of One-third? One-th
Airida [17]

Answer:

Step-by-step explanation:

Given the equation \frac{1}{3}(x+9) = -12

Step 1;

Expand the bracket at the right hand side of the equation to have:

\frac{1}{3}x +\frac{1}{3}(9) = -12\\\frac{1}{3}x+3=-12\\subtracting\ 3\ from\ both\ sides\\\frac{1}{3}x+3-3=-12-3\\\frac{1}{3}x=-15\\

Taking the reciprocal of both sides:

\frac{3}{x} = \frac{-1}{15} \\ cross\ multiplying\\-x =45\\x=-45
