Simplify (2/9)^3 A.6/9 B.8/729 C.2/720

saw5 [17]

Answer:

$\frac{8}{729}$

Explanation:

Before we begin, remember that:

( $\frac{a}{b}$ )ⁿ = $\frac{a^n}{b^n}$

This means that power is distributed in case of division

The given is:

$(\frac{2}{9} )^3$

Applying the above rule, we would get:

$(\frac{2}{9} )^3$ = $\frac{2^3}{9^3} = \frac{2*2*2}{9*9*9} = \frac{8}{729}$

Hope this helps :)

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 5x - 2y = 9 3x + 4y = - 5 O A. (5,

marta [7]

Answer:

Step-by-step explanation:

4(5x-2y=9)

-2(3x+4y=-5)

20-20x-8y=36

+6x-6x-8y=10

36-20x=10+6x-6x

36-36-20x-6x=10

-26x=10-36

-26x/-26=-26/-26

x=1

Work out, giving your answer in its simplest form: 4/7 divided by 2 1/3

kirill [66]

Answer:

12/49

Step-by-step explanation:

First write 2 1/3 as a improper fraction, to do that, first multiply the 2 by the denominator, then add it with the 1, which will result in 7/3

when doing division of fraction you have to remember this, KFG

KFG: Keep Flip Change

you keep the first number or fraction, which is 4/7

then you flip the sign, so you change division in to multiplication

after that, you change or write the reciprocal of the second number or fraction, so 7/3 will be 3/7

Now the equation is

4/7 times 3/7, which is 12/49
