Solve the formula c=Nd for d

2 answers:

Answer:

c/n=d

Step-by-step explanation:

To solve for d, we need to get d by itself

c=nd

d is being multiplied by n. To undo this, divide both sides by n, since division is the opposite of multiplication. This will cancel out the n on the right side, and leave d by itself.

c/n=nd/n

c/n=d

Answer:

$\frac{c}{n} = d$

Step-by-step explanation:

To get d isolated we have to divide both sides by N to cancel the out the N on the side which d is on. Once we do that d is alone and on the other side we have c over n.

I could use some help doing this simple math problem lol.

alexira [117]

$D:k-9\geq 0 \wedge k\geq0\\
D:k\geq 9 \wedge k\geq0\\
D:k\geq 9\\
\sqrt{k-9}-\sqrt k=-1\\
\sqrt{k-9}=-1+\sqrt k\\
k-9=(-1+\sqrt k)^2\\
k-9=1-2\sqrt k+k\\
2\sqrt k=10\\
\sqrt k =5\\
k=25

-2x = 16–8y<br> x+4y= 25<br> Solve by substitution

ra1l [238]

Answer:

( $\frac{17}{2}$ , $\frac{33}{8}$

Step-by-step explanation:

Given the 2 equations

- 2x = 16 - 8y → (1)

x + 4y = 25 → (2)

Rearrange (2) expressing x in terms of y by subtracting 4y from both sides

x = 25 - 4y → (3)

Substitute x = 25 - 4y into (1)

- 2 (25 - 4y) = 16 - 8y ← distribute left side

- 50 + 8y = 16 - 8y ( add 8y to both sides )

- 50 + 16y = 16 ( add 50 to both sides )

16y = 66 ( divide both sides by 16 )

y = $\frac{66}{16}$ = $\frac{33}{8}$

Substitute this value into (3) for corresponding value of x

x = 25 - 4 × $\frac{33}{8}$ )

= $\frac{50}{2}$ - $\frac{33}{2}$ = $\frac{17}{2}$

Solution is ( $\frac{17}{2}$ , $\frac{33}{8}$ )

Express: 0.006 in exponeutialform

Yuri [45]

6×10^-3

Step-by-step explanation:

0.006

Move the point to the front of the first number that is from 1 to 9.

In the question it's 6, so you move it to the front of 6 .

And because it's from back to front it has to have a negative sign in its power

which is going to be

6× 10^-3

where 6=the number from 1 to 9

^ means raise to power or power of

-3= the negative power
