Solve the following equation: *<br> -9 (t – 2) = 4(t – 15)
iragen [17]

Answer:

6 =t

Step-by-step explanation:

-9 (t – 2) = 4(t – 15)

Distribute

-9t +18 = 4t -60

Add 9t to each side

-9t +18+9t  = 4t+9t -60

18 = 13t -60

Add 60 to each side

18+60 = 13t-60+60

78 = 13t

Divide each side by 13

78/13 = 13t/13

6 =t

tester [92]

Answer:

Position of the submarine now relative to the water surface =-47\ \frac{3}{4}

Step-by-step explanation:

It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.

Now we need to find about what is the position of the submarine now relative to the water surface.

Downward navigation means we 15 1/2 is negative

so we will just add both values to get the final answer:

Position of the submarine now relative to the water surface = -32\ \frac{1}{4}-15\ \frac{1}{2}

=-32\ \frac{1}{4}-15\ \frac{2}{4}

=-47\ \frac{3}{4}
