Answer:

0.81

Step-by-step explanation:

The letters between L and P are M,N,O.

It is inclusive, so we have 5 letters L,M,N,O,P.

The letters which we can choose we have 26-5=21.

The probability to choose a letter not between L and P is 21/26=0.81

The solution is 0.81, ie,

Frank bought 6 pens and 3 highlighters in the school store and paid $21 for the whole purchase. His friend, Andy, paid $19 for 2

vovangra [49]

Answer:one pen = $1.50

Step-by-step explanation:

See picture for the math if that helps

Using p for pens, h for highlighter,

A for first equation

B for second equation

I used equation A to reduce to a usable substitute by dividing all by 3

And then isolating “h”.

Now substitute the value of “h” into equation B and solve for “p”

P=$1.50

To check your work, substitute p ($1.50) into equation B and solve for “h”

h=$4.00

Now substitute the p and h values into either equation A or B and solve, they equal the numbers given

Write down the reciprocal of<br> 1/3

Leokris [45]

<h2><u>RECIPROCAL</u></h2>

<h3>ANSWER: </h3>

$\boxed{ \bold{3 \: \: \: or \: \: \: \frac{3}{1} }}$

<h3>EXPLANATION:</h3>

As we can see above, it's clear that 3 and 1/3 are reciprocals of each other.

And we can find the reciprocal of 1/3 by forming a fraction and to multiply the numerator and denominator by 3.

$\\ \large \tt \: \frac{1 \times 3}{ \frac{1}{3} \times 3 } = \bold{ \frac{3}{1} = 3} \\ \\$

Hence, 3/1 or 3 is the correct answer.
