The quotient of 9 times an unknown number and 16 is 81. What is the value of the unknown number?

Answer 1

Genesis Allen

#144#

the equation in question can be rewritten as

#(9n)/ 16 = 81#

where #n# is the unknown number.

to solve:

multiply both sides by #16#, so there are no fractions in the equation:

#9n = 81 * 16 = 1296#

divide both sides by #9# to find #n:#

#n = 1296/9#

#= 144#

To find the unknown number, solve the equation:

( \frac{9x}{16} = 81 )

First, multiply both sides by 16 to isolate the variable:

( 9x = 81 \times 16 )

Then, divide both sides by 9:

( x = \frac{81 \times 16}{9} )

( x = \frac{1296}{9} )

( x = 144 )

Therefore, the value of the unknown number is 144.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
