Answer:

-1

Step-by-step explanation:

Given the equation :

2(3x – 1) > 4x – 6

Open the bracket :

6x - 2 > 4x - 6

Collect like terms

6x - 4x > - 6 + 2

2x > - 4

Divide both sides by 2

2x /2 > - 4/2

x > - 2

Since x > - 2

-10, - 5, - 3 are all < - 2

Hence, the only option greater than - 2 is - 1

x = -96

Answer:

Step-by-step explanation:

This is a difference of squares.

√x^2 - √49  is the basic formula for factoring a difference of squares. The  idea is that the middle term has been cancelled out.

√x^2 = x

√49 = 7

(x - 7)(x + 7) is the way this factors.

(x - 7)(x + 7)

===========

(x + 7)

The (x +7) in the numerator cancels with the (x + 7) in the denominator.

The answer is (x - 7)

====================================================

She might have wanted you to do it like this.

(x + 7) || x^2  + 0x    - 49  || x     -   7

            x^2 + 7x  ........... Subtract

           ==========

                   -7x      - 49

                   -7x      - 49   ...... Subtract.

                   =============

                           0

Or she might have seen you do this

x^2 - 49          x^2        49

=======   =   ===    -   =====

x + 7                x             7

Every math teacher freaks when they see this. I hope I didn't put ideas in your head.

But if you got the answer by doing what I did, you got it right.

Answer:

$37.

Step-by-step explanation:

Firstly, let's set the price of each pair of shoe to be x.

Since each pair of shoes costs the same, and there are three pairs, we can set the original price to be 3x.

Now, to apply the shipping charge, all we have to do is add 7.50 to 3x, getting 3x + 7.5.

Next, to apply a 6% tax, we can multiple the whole expression by (100% + 6%), getting (3x + 7.5) [tex]\cdot[/tex] 106%.

Since the whole bill foots to a total of $126.81, we can set the final equation to be:

[tex](3x + 7.5) \cdot 106\% = $126.81[/tex]

[tex](3x + 7.5) \cdot \frac{106}{100} = $126.81[/tex]

[tex]3x + 7.5 = $126.81 \cdot \frac {50}{53}[/tex]

[tex]3x = $119.6 - 7.5[/tex]

[tex]3x = 112.1[/tex]

[tex]x \approx \$37[/tex]

Answer:

Cost of each chocolate bar  = $2.65

Cost of each blow pop  = $1.25

Step-by-step explanation:

Let x = Cost of chocolate bar

y= Cost of blow pops

We can make system of equations and find value of x and y

You bought 5 chocolate bars and 8 blow pops for $23.25.[tex]5x+8y=23.25[/tex]

Your sister bought 2 chocolate bars and 13 blow pops for $21.55. [tex]2x+13y=21.55[/tex]

Let:

[tex]5x+8y=23.25--eq(1)\\2x+13y=--eq(2)[/tex]

Multiply eq(1) with 2 and eq(2) with 5 and subtract

[tex]10x+16y=46.5\\10x+65y=107.75\\- \ \ \ - \ \ \ \ \ \ - \\------\\-49y=-61.25\\y=\frac{-61.25}{-49} \\y=1.25[/tex]

So, value of y = 1.25

Putting value of y in eq(1) to find value of x

[tex]5x+8y=23.25\\5x+8(1.25)=23.25\\5x+10=23.25\\5x=23.25-10\\5x=13.25\\x=13.25/5\\x=2.65[/tex]

Value of x = 2.65

So, Cost of each chocolate bar = x = $2.65

Cost of each blow pop = y = $1.25

Answer: 14 cupcakes

Step-by-step explanation:

sugar available is 7.33 cups, the 1/3 cup of sugar is no use due to the fact that you need 1/2 cup of sugar to make a single cupcake.

for Spanish readers: el azúcar disponible es de 7.33 tazas, el 1/3 de taza de azúcar es inútil debido al hecho de que necesitas 1/2 taza de azúcar para hacer un solo cupcake.

for French readers:

le sucre disponible est de 7,33 tasses, 1/3 de tasse de sucre n'est pas utile car vous avez besoin de 1/2 tasse de sucre pour faire un seul petit gâteau.

hopefully this helped! :D

Answer:

one cupcake= 1/2 cup of sugar

Total sugar availability: 7 and 1/3 or 7.33

Now go ahead and divide 7.33/.50

Notice that for every cup of sugar you can make exactly 2 cupcakes

Therefore you can make a total or 7*2=14 cupcakes

You are unable to utilize the rest of the 1/3 cup because you need 1/2 to make a singular cupcake

Answer:

Yew, he has enough money to buy the guitar in september.

Step-by-step explanation:

300*0.75=225        300+225=525

650*0.35=195            650-195=455

sales tax:    455*0.05=22.75          455+22.75=477.75

Yes , Arnold have enough savings to buy the guitar

Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the original price of the guitar be = $ 650

Let the initial savings of Arnold be = $ 300

Now , Arnold saved 75 % more than what he actually had

And , the equation will be

So , the new savings of Arnold is = 300 + ( 75/100 ) x 300

The new savings of Arnold is = 300 + ( 300 x 0.75 )

The new savings of Arnold is = 300 + 225

The new savings of Arnold is = $ 525

Now , the price of the guitar is discounted by = 30 %

And , the equation will be

So , the new price of the guitar after discount is = 650 - ( 30/100 ) x 650

The new price of the guitar after discount is = 650 - ( 650 x 0.30 )

The new price of the guitar after discount is = 650 - 195

The new price of the guitar after discount is = $ 455

Now , A sales tax of 5 % is priced on the guitar

And , the equation will be

So , the sale price of the guitar is = 455 + ( 5/100 ) x 455

The sale price of the guitar is = 455 + 22.75

The sale price of the guitar is = $ 477.75

Now , the new savings of Arnold is greater than the sale price of the guitar

$ 525 > $ 477.75

Therefore , Arnold have enough savings to buy the guitar

Hence , Yes , Arnold have enough savings to buy the guitar

Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75
