Answer:

-12

Step-by-step explanation:

−5(3m+6)=−3(4m−2)

(−5)(3m)+(−5)(6)=(−3)(4m)+(−3)(−2)(Distribute)

−15m+−30=−12m+6

−15m−30=−12m+6

Step 2: Add 12m to both sides.

−15m−30+12m=−12m+6+12m

−3m−30=6

Step 3: Add 30 to both sides.

−3m−30+30=6+30

−3m=36

Step 4: Divide both sides by -3.

−3m

−3

=

36

−3

Answer:

\huge\boxed{m=-12}

Step-by-step explanation:

In order to solve for this equation, we can simplify this expression until we have m isolated on one side of it.

-5(3m+6)=-3(4m-2)

Distribute the left and right side:

-15m-30=-12m+6

Add 30 to both sides:

-15m=-12m+36

Add 12m to both sides:

-3m=36

Divide both sides by -3:

m = -12

So m = -12.

Hope this helped!

The speed of a ship is given by d3, where d is the distance the ship travels in 3 hours. if the ship travels 48 miles in 3 hours
Kay [80]
Hello there! Thank you for asking your question here at Brainly! I will be assisting you today with answering this problem, and will teach you how to handle it on your own in the future.

First, let's take a look at our problem.
"The speed of a ship is given by D3, where D is the distance the ship travels in 3 hours. If the ship travels 48 miles in 3 hours, what is the speed of the ship?"

To solve for this, we need to understand the formula for speed.
The formula for speed is:
Speed = \frac{Distance}{Time}

Now that we have our formula, let's define our variables.

So, we have our distance, 48 miles, and our time, 3 hours.
Let's plug in these numbers to the formula.
Speed = \frac{48}{3}

Simplify the fraction to get the speed.
\frac{48}{3} = 16.

Your final equation is:
Speed = 16.

Our final answer is 16 mph.

I hope this helps!

Find the length of x
Goshia [24]

Answer:

x = 8\sqrt{2}

Step-by-step explanation:

The triangle is isosceles with legs congruent, both x

Using Pythagoras identity in the right triangle

x² + x² = 16²

2x² = 256 ( divide both sides by 2 )

x² = 128 ( take the square root of both sides )

x = \sqrt{128} = \sqrt{64(2)} = \sqrt{64} × \sqrt{2} = 8\sqrt{2}
