Answer:

Answers 2, 3, and 5 are correct

Step-by-step explanation:

<u>BELOW ARE THE EQUATIONS FOR EACH:</u>

2.) D=M÷V

3.) M=D*V

5.) V=M÷D

The true statements are:

2) To find density, divide the mass by the volume.

3) To find mass, multiply the density times the volume.

5) To find volume, divide the mass by the density.


The equation for density is D=m/V (where D is density, m is mass, and V is volume).  

To find the equation for mass, solve for the m variable in the equation by multiplying both sides by V.  The equation is m=DV.

To find the equation for volume, solve for the V variable in the equation by multiplying both sides by V and then dividing both sides by D.  The equation is V=m/D.


Hope this helps!!

K-17=-12 I need help solveing this
Fed [463]
Remember, you can do ANYTHING to an equaiton as long as you do it to BOTH SIDES

we can try to get k by itself bymaking that -17 into 0 since k+0=k

-17+17=0 right so

K-17=-12
add 17 to BOTH SIDES
K+17-17=17-12
K+0=5
K=5

Solve 4x = -28 algebriaclly​
Ierofanga [76]

Hey there!

4x = –28

DIVIDE BOTH of your SIDES by 4

4x/4 = –28/4

CANCEL: 4/4 because that gives you 1

KEEP: –28/4 because it helps us solve for “x”

x = –28/4

–28/4 = –7

Answer: x = –7 ☑️

Good luck on your assignment and enjoy your day!

Match the width with the go given area.
LekaFEV [45]

Hello!

<h2>Answer:</h2>

\boxed{ \bf 1.~l~=~9.25~cm;~A~=~55.5~cm^2~matches~with~the~last~option~w~=~6~cm.}

\boxed{ \bf 2.~l~=~7.5~cm;~A~=~48.75~cm^2~matches~with~the~second~option~w~=~6.5~cm.}

\boxed{ \bf 3.~l~=~5~cm;~A~=~44~cm^2~matches~with~the~third~option~w~=~8.8~cm.}

\boxed{ \bf 4.~l~=~5~cm;~A~=~31.25~cm^2~matches~with~the~first~option~w~=~6.25~cm.}

<h2>__________________________________</h2><h2>Explanation:</h2>

We already know that the formula for area of a rectangle is A = l × w.

Notice how the width and the length are being multiplied to find the area.

Well, to find the width, we must do the <em>opposite</em> of multiplication, which is division.

Since we already have the length, all we have to do is divide the area by the length for each of the questions.

1:

A = l × w

55.5 = 9.25 × w

\frac{55.5}{9.25} = 6

2:

A = l × w

48.75 = 7.5 × w

\frac{48.75}{7.5} = 6.5

3:

A = l × w

44 = 5 × w

\frac{44}{5} = 8.8

4:

A = l × w

31.25 = 5 × w

\frac{31.25}{5} = 6.25
