ANTONII [103]3 years ago

Answer:

((x - (2x - 3)/(3x - 2))/(3x + 4)

and its fractional equivalent

2x - 3

x - ------

3x - 2

----------

3x + 4

it is easier to see the relation between the various parts, and how it

might be simplified, when you see it in the latter form. Notice that I

didn't have to use parentheses at all; that's because the bar serves

the double purpose of indicating division and of separating the

divisor from the dividend. In fact, this usage derives in part from an

old use of the bar (called a vinculum) to do what we usually do with

parentheses today, by putting a bar above any group of symbols that

are to be kept together:

Evaluate the expressions. 8!-6!, 7!-5!, and 12!/8! BRAINLIST 5 min left plz hurry

nordsb [41]

Answer:

The evaluated expressions are $8!-6!=39600$ , $7!-5!=4920$ and $\frac{12!}{8!}=11880$

Step-by-step explanation:

The factorial of a positive integer n is the product of all positive integers less than or equal to n:

$n!=n\times (n-1)\times (n-2)\times (n-3)\times ...\times 3\times 2\times 1$

The factorial of n is denoted by n!

Now to find the expressions 8!-6!, 7!-5!, and 12!/8! :

Given expression is 8!-6!:

$8!-6!=[8\times (8-1)\times (8-2)\times (8-3)\times (8-4)\times (8-5)\times (8-6)\times (8-7)]- [6\times (6-1)\times (6-2)\times (6-3)\times (6-4)\times (6-5)]$ (By using factorial of n formula)

$=[8\times 7\times 6\times 5\times 4\times 3\times 2\times 1]- [6\times 5\times 4\times 3\times 2\times 1]$

$=[6\times 5\times 4\times 3\times 2\times 1][(8\times 7)-1]$

$=[720][56-1]$

$=[720][55]$

$=39600$

Therefore $8!-6!=39600$

Given expression is 7!-5! :

$7!-5!=[7\times (7-1)\times (7-2)\times (7-3)\times (7-4)\times (7-5)\times (7-6)]-[5\times (5-1)\times (5-2)\times (5-3)\times (5-4)]$ (By using factorial of n formula)

$=[7\times 6\times 5\times 4\times 3\times 2\times 1]- [5\times 4\times 3\times 2\times 1]$

$=[5\times 4\times 3\times 2\times 1][(7\times 6)-1]$

$=[120][42-1]$

$=[120][41]$

$=4920$

Therefore $7!-5!=4920$

Given expression is $\frac{12!}{8!}$

$\frac{12!}{8!}=\frac{12\times (12-1)\times (12-2)\times (12-3)\times (12-4)\times (12-5)\times (12-6)\times(12-7)\times (12-8)\times (12-9)\times (12-10) \times(12-11)}{8\times (8-1)\times (8-2)\times (8-3)\times (8-4)\times(8-5)\times (8-6)\times (8-7)}$ (By using factorial of n formula)

$=\frac{12\times 11\times 10\times 9\times 8\times 7\times 6\times 5\times4\times 3\times 2\times 1}{8\times 7\times 6\times 5\times4\times 3\times 2\times 1}$

$=12\times 11\times 10\times 9$

$=11880$

Therefore $\frac{12!}{8!}=11880$

The store is selling lemons at $0.58 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough l

avanturin [10]

Answer:

$4.64

Step-by-step explanation:

1 cup = 16 tablespoons

$\frac{1}{2}$ cup = 8 tablespoons

Each lemon yields about 2 tablespoons of juice. You need 8 tablespoons for one lemon pie, so you need $8\div 2=4$ lemons for one pie and $4\times 2=8$ lemons for two pies.

The store is selling lemons at $0.58 each, hence, 8 lemons will cost

$\$0.58\times 8=\$4.64$
