Make U the subject of the formula <br> D = ut + kt2

natali 33 [55]

Remark

I'm going to interpret this equation as

D = ut + kt² The only difference is the 2.

Solution

Subtract kt² from both sides.

D - kt² = ut Now divide by u on both sides.

$\dfrac{D - kt^2}{t} = \dfrac{ut}{t}$

The t's cancel out. on the right. You are left with u on the right.

$\dfrac{D - kt^2}{t} =\text{u}$

Which value of n makes the following equation true?

grin007 [14]

Answer: d. 512

Step-by-step explanation:

You need to remember that:

$(\sqrt[3]{x})^3=x$

Then, given the equation:

$\sqrt[3]{n}=8$

You can find the value of "n" that make the equation true, by solving for "n".

So, to solve for "n", you need to raise both side of the equation to power 3. Therefore, you get:

$\sqrt[3]{n}=8$

$(\sqrt[3]{n})^3=(8)^3$

$n=512$

Then, the value of "n" that makes the equation $\sqrt[3]{n}=8$ true is: 512 (You can observe that this matches with the option d).

Use substitution method <br>3x +4y+175x-2y=11

Viefleur [7K]

$3x +4y+175x-2y=11$

$4y-2y+175x+3x=11$

$2y+178x=11$

$2y=11-178x$

$y=\frac{11-178x}{2}$

$y=-89x+\frac{11}{2}$

$178x=-2y+11$

$x=\frac{-2y+11}{178}$

$x=\frac{-1}{89} y+\frac{11}{178}$
