<span>5(x+1)= 4(x-1)+x
5x + 5 = 4x - 4 + x
5x +5 = 5x -4

A table costs $350. There is also a sales tax of 7%. How much does the table cost, including sales tax?

IrinaVladis [17]

Tax
$350x0.07
=$24.50

(0.07 is the 7% tax in decimal form)

Total cost
$350+$24.50
=$374.50

OR

$350x107%
=$374.50

1.07 is the table cost (100%) plus the sales tax (7%)

The table costs $374.50 with tax.

In your notebook, set up the following subtraction in a vertical format and select the correct answer. Find 2p 2 3p - 4 less - 2

Elena L [17]

The equation in the reduced form of the equation is $\rm 4p^ 2 + 6p - 8$ .

Given that,

Equation; $\rm 2p^ 2 + 3p - 4\ by\ -2p ^2 - 3p +4$

We have to reduce the equation.

According to the question,

To reduce the equation means we need to subtract one equation from the other.

To determine the reduced form of the equation following all the steps given below.

Equation; $\rm 2p^ 2 + 3p - 4\ by\ -2p ^2 - 3p +4$

Subtraction equation 1 from equation 2,

$\rm = \rm 2p^ 2 + 3p - 4\ -(-2p ^2 - 3p + 4)\\\\= 2p^ 2 + 3p - 4\ -(-2p ^2 -3p +4)\\\\ = 2p^ 2 + 3p - 4+2p^ 2 + 3p - 4 \\\\ = 4p^ 2 + 6p - 8$

Hence, The equation in the reduced form of the equation is $\rm 4p^ 2 + 6p - 8$ .

The latest online craze is a new game, Khan on Seven. You get 100 points for playing the game. In addition, you get 50 points fo

Blizzard [7]

Answer: $50x+100\geq18,000$

Step-by-step explanation:

Let w denotes a seven letter word which Sal will need to make to break the record.

Since you get 50 points for each seven-letter and 100 points for playing the game.

Then the total points earned by you by making w seven letters words will be:

$50x+100$

Since, Sal wants to break that record, and needs 18,000 points or more to do so.

Then , the required inequality will be :

$50x+100\geq18,000$

Help due in 45 minutes!!

Answer:

(14,-1)

Step-by-step explanation:

okay so first you need to use the "x=4y+10" in the first equation.

Rewrite as

3(4y+10) +11y=7

Distribute the 3(4y+10)

Rewrite as

12y+30

You'll have the equation

12y +30 +11y= 7

Subtract the 7 from both sides

12y+30+11y-7= 0

Combine like terms

23y+23=0

the best thing to do here is divide the equation by 23.

23/23 = 1

you'll have

y + 1 = 0

this simplifies to

y= -1

use this y value to solve for x

the easiest way to do this is start with the equation

x = 4y +10

Substitute the y for -1

x = -4(-1) +10

x = 4 +10

x = 14

the solution point is

(14,-1)
