Answer 1

Answer:

[tex]-x + 9[/tex]

Step-by-step explanation:

Hello!

We want to combine any like terms and distribute the signs properly to the terms in the parentheses.

First, remove the parentheses by distributing the signs:

[tex]-(2x - 1) + 3(x + 4) - 2(x + 2)[/tex][tex]-(2x) - (-1) + 3(x) + 3(4) - 2(x) - 2(2)[/tex]

Remember that negative times negative is positive
[tex]-2x + 1 + 3x + 12 - 2x - 4[/tex][tex]-2x + 3x - 2x + 1 + 12 - 4[/tex][tex]-x + 9[/tex]

The simplified form is [tex]-x + 9[/tex].

Another way to think about the negative sign is by replacing it with -1, so essentially you are multiplying the whole parentheses by -1.

Answer 2
-(2x-1)+3(x+4)-2(x+2)-2x+1+3x+12-2x-4-4x+3x+1+8-x+9

which expression uses the commutative property to make it easier to evaluate -6/5 x 11 x 5/3?
Please hurry, will give brain list and all points too!!!!

Answers

Answer:

-6/5 x 5/3 x 11

Step-by-step explanation:

the commutative property states that x * y = y * x where "x" is a number and "y" is also a number and also x+y=y+x. also "*" is the multiplication symbol

-6/5*11*5/3 can be re-arranged into 11*-6/5*5/3 you can cancel the numbers to get 11*-2/3*5=55*-2/3=-110/3

Answer:

-22

Step-by-step explanation:

-6/5*11*5/3=(-6/5)(5/3)(11/1)=(-6/3)(11/1)=-66/3=-22

Clyde is baking, and the recipe requires 1 1/3 cups of flour. Clyde has 2 cups of flour, but he is doubling the recipe to make twice as much. How much more flour does Clyde need? Write an equation to represent the problem. Let c represent the amount of flour Clyde needs, and then solve it.

Answers

Answer:

Clyde needs 2/3 cup more.

Step-by-step explanation:

The equation can be:

C = 2 - 2( 1   1/3 )

If Clyde is doubling the recipe, he will need 2 2/3 cups of flour. 2 2/3 minus 2 (the amount he has) will give you your answer.

Answer:

The total least sale amount is $5,000,000

Step-by-step explanation:

Given as :

The base salary amount of Carmen = $125,000

The commission percentage on total sale = 4%

The performance bonus amount = $25,000

The total compensation amount last year = $350,000

Let The total sale amount = $x

According to question

Total compensation amount last year = base salary amount + percentage on total sale + performance bonus amount

I.e  $350,000 =  $125,000 + 4% of x + $25,000

Or, $350,000 =  $150,000 + 4% of x

Or, 4% of x =  $350,000 - $150,000

Or, 4% of x =  $200,000

Or,  × x =  $200,000

Or, x =

∴   x = $5,000,000

So, The total sale amount = x = $5,000,000

Hence, The total least sale amount is $5,000,000  Answer

Step-by-step explanation:

The answer is 5,000,000
