T=pd/2xsolve for Xi always get confused when theirs more then one letter

When there's more than one letter, and you just have to solve for one variable, you can just solve it like you would any other equation. Treat the other variables like numbers and add, subtract, multiply, and divide them to both sides of the equation in order to isolate the variable you want to solve for.

$t= \frac{pd}{2x} \\ \\ t*2x= \frac{pd}{2x}*2x \\ \\ 2tx=pd \\ \\ \frac{2tx}{2t} = \frac{pd}{2t} \\ \\ x=\frac{pd}{2t}$

OK. Then let's just give the other letters different names.

Instead of T = p d / 2x

let's write Tiger = pig dog / 2x

Multiply each side by 2x : 2x Tiger = pig dog

Divide each side by Tiger : 2x = pig dog / Tiger

Now divide each side by 2 : x = pig dog / 2 Tiger

Of course you would not hand it in on a homework sheet like that.
You would change it back to
x = p d / 2 T .

Answer:

terminating

Step-by-step explanation:

if the given fraction is terminating then prime factors of denominator should be 2^n x 5^m where m and n are whole number

Find the height of a clock tower if the angle of elevation from a horizontal point 430 m from its base is 40°.

zaharov [31]

$\\ \sf\longmapsto tan40=\dfrac{P}{430}$

$\\ \sf\longmapsto 0.83=\dfrac{P}{430}$

$\\ \sf\longmapsto P=430(0.83)$

$\\ \sf\longmapsto P\approx361m$

P=Height of tower

The Sugar Sweet Company is going to transport its sugar to market. It will cost $4500 to rent trucks, and it will cost an additi

Elza [17]

C = 4500 + 150s

4500 is fixed, so what remains is just 150$ per ton of sugar (so 150 x s)

If we substitute 12 for s we get:

C = 4500 + 150*12

C = 6300

Use properties to rewrite the given equation. Which equations have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p? Select t

Anastaziya [24]

The equations which gave the same solution as; 2.3p – 10.1 = 6.5p – 4 – 0.01p are;

2.3p – 10.1 = 6.49p – 4 and
230p – 1010 = 650p – 400 – p

<h3>Which equations have the same solution as the given equation?</h3>

It follows from the answer choices that the equation; 2.3p – 10.1 = 6.49p – 4 is equivalent to the given equation as the algebraic sum of p variables is evaluated on the right hand side.

The second equation; 230p – 1010 = 650p – 400 – p also is equivalent to the given equation, when multiplied through by 100.
