3 to the 2 power times 5 to the 3 times 8 divided by 3 times 5 to the 3 times 8

Answer:

Step-by-step explanation:

First condense all the numbers with exponents:

3² x 5³x 8 divided by 3 x 5³ x 8

27 x 125 x 8 divided by 3 x 27 x 8

Then multiply 27 , 125 ,and 8

27 x 125 x 8 =27000

Then multiply 3, 27 ,and 8

3 x 27 x 8 = 648

Then divide 27000 by 648

27000 / 648 = 41.6666666667

Which rounds to about: 42

My teacher wanted us to try this out, but I don't understand it as much.

statuscvo [17]

solve for the indicated variable means isolate that variable.

Ans(7)

P=IRT (T)

that means solve for T or make T alone on one side of equal.

To do that we just need to move IR on the left side

So we get:

$\frac{P}{IR}=T$

Hence final answer will be $T=\frac{P}{IR}$

Ans(8)

2x-3y=8 (y)

-3y=8-2x

$y=\frac{8-2x}{-3}$

------------

Ans(9)

V=LWH (L)

$L=\frac{V}{WH}$

------------

Ans(10)

A=2(L+W) (w)

A=2L+2W

A-2L=2W

$\frac{A-2L}{2}=W$

$W=\frac{A-2L}{2}$

------------

Ans(11)

ax+by=c (y)

by=c-ax

$y=\frac{c-ax}{b}$

------------

Ans(12)

$P=\frac{R-C}{N}$ (R)

PN=R-C

PN+C=R

R=PN+C
