Step-by-step explanation:

Given

4a + x = 3b ( isolate x on the left side by subtracting 4a from both sides )

Answer:

The original cost is $130

Step-by-step explanation:

Step one:

given data

We are told that Rey paid $91 for a watch that was on sale for 30%

let the original cost be x

so that 30% off x= $91 --------not the word  OFF not OF

Required

the original cost x

Step two

hence

x- 30/100*x= 91

x-0.3x=91

0.7x= 91

divide both sides by 0.7

x= 91/0.7

x=$130

Answer:

a) x = -2/3    y = -26/3 or -8 2/3

b) x = 12      y = 5

Step-by-step explanation:

a) since both equations begin with 'y =' you can set them equal to each other

4x - 6 = x - 8

3x = -2

x = -2/3

sub x value to find y:

y = 4(-2/3) - 6

   = -8/3 + (-18/3)

   = -26/3

Answer:

[tex]y = 4x + 36[/tex]

[tex]y = 48[/tex] when [tex]x = 3[/tex]

Step-by-step explanation:

Given

x = input

y = output

Required

Determine the equation of y

The process to get y is as follows:

Multiply x by 4: x * 4

Increase the result by 36: x * 4 + 36

Hence:

[tex]y = x * 4 + 36[/tex]

[tex]y = 4x + 36[/tex]

Solving y when x = 3

Substitute 3 for x in [tex]y = 4x + 36[/tex]

[tex]y = 4 * 3 + 36[/tex]

[tex]y = 12 + 36[/tex]

[tex]y = 48[/tex]

Answer:

9/16

Step-by-step explanation:

(5/8 * 2/2) - (1/16 - 1/1)

10/16 - 1/16

10-1//16 = 9/16

5/8 - 1/16 = 9/16

(5*16) - (1*8) / 8 * 16

80-8/ 128

72/128

72/8

128/8= 9/16

5/8 - 1/16 = 9/16

Answer:

1) The discount is $4.05

The sale price is $18.45

2) The discount is $10

The sale price is $30

3) The discount is $2.6

The sale price is $23.4

Step-by-step explanation:

1) What is the discount and sale price for a haircut that originally cost $22.50 with an 18% discount.

Actual Price= $22.50

Discount = 18%

Finding discount:

[tex]18\%\:of\:22.50\\=\frac{18}{100}\times 22.50\\=4.05[/tex]

So, the discount is $4.05

Finding Sale Price

The sale price can be found by: [tex]Sale\;Price=Actual\:Price-Discount[/tex]

Putting values and finding sale price:

[tex]Sale\:Price=22.50-4.05\\Sale\:Price=18.45[/tex]

The sale price is $18.45

2) What is the discount and sale price for a sweatshirt that originally priced $40.00 with an 25% discount.

Actual Price= $40.00

Discount = 25%

Finding discount:

[tex]25\%\:of\:40.00\\=\frac{25}{100}\times 40.00\\=10[/tex]

So, the discount is $10

Finding Sale Price

The sale price can be found by: [tex]Sale\;Price=Actual\:Price-Discount[/tex]

Putting values and finding sale price:

[tex]Sale\:Price=40.00-10\\Sale\:Price=30[/tex]

The sale price is $30

2) What is the discount and sale price for a large pizza that originally cost $26.00 with an 10% discount.

Actual Price= $26.00

Discount = 10%

Finding discount:

[tex]10\%\:of\:26.00\\=\frac{10}{100}\times 26.00\\=2.6[/tex]

So, the discount is $2.6

Finding Sale Price

The sale price can be found by: [tex]Sale\;Price=Actual\:Price-Discount[/tex]

Putting values and finding sale price:

[tex]Sale\:Price=26.00-2.6\\Sale\:Price=23.4[/tex]

The sale price is $23.4

Answer:

the price per gallon for each drink is $4.5 and $4.75 respectively

Step-by-step explanation:

The computation of the price per gallon for each drink is as follows;

Let us assume the ice tea be x

And, lemonade be y

So the equations are

2x +  3y = $23.25 .......(i)

5x + 4y = $41.50     ................(ii)

Now multiplied by 5 and 2 in equation 1 and 2

10x + 15y = $116.25

10x + 8y = $83

7y = 33.25

y = $4.75

Now put the y value in any of the equation

2x + 3($4.75) = $23.25

x = $4.5

So, the price per gallon for each drink is $4.5 and $4.75 respectively

Option A

The system of inequalities

x + y ≤ 200

4x + 3y ≤ 750

Step-by-step explanation:

Let the

Number of Adults = x

Number of campers = y

A summer camp cookout is planned for the campers and their families.

There is room for 200 people.

x + y ≤ 200

Each adult costs $4, and and each camper costs $3. There is a maximum budget of $750.

Maximum means the total cost is equal to or less than $750

$4 × x + $3 × y ≤ $750

4x + 3y ≤ 750

The system of inequalities

x + y ≤ 200

4x + 3y ≤ 750

Option A is correct

Answer:

direct variation equation: y = 13/4x

y = -19.5 when x = -6

Step-by-step explanation:

y = kx  where 'k' is the constant to proportionality

13 = 4k

k = 13/4

equation:  y = 13/4x

plug in -6 for 'x' to find value of 'y'

y = 13/4(-6)

y = -19 1/2

Answer:

According to the integral root theorem the only possible real, integral zeros are +/- factors of (10*3 - 8)

... or factors of 992(+/-).  you can test by direct substitution.  No positive values are roots ... try 1, 1332, but as x increases so does y ...  so there are no positive roots.

  Roots, means y = 0 ...  so (x + 10)^3  = 8 ... take cube root ... x + 10 = 2  .. x = -8

x = -8 is a root

Testing other negatives and the y values are not zero but tend toward - infinity.

So the only real zero is x = -8

Answer:

it helps you

Step-by-step explanation:

this is for y = (x-10)^3 - 8

According to the integral root theorem the only possible real, integral zeros are +/- factors of (10*3 - 8)

... or factors of 992(+/-). you can test by direct substitution. No positive values are roots ... try 1, 1332, but as x increases so does y ... so there are no positive roots.

Roots, means y = 0 ... so (x + 10)^3 = 8 ... take cube root ... x + 10 = 2 .. x = -8

x = -8 is a root

Testing other negatives and the y values are not zero but tend toward - infinity.

So the only real zero is x = -8

Similarly for y = (x + 7)^3 +2 = 0

(x + 7)^3 = -2

x + 7 = cube root (-2)

x = -7 + cube root (-2) <<< the only real root

Step-by-step explanation:

-6x + 5 > -1

-6x > -6 (subtract 5 on both sides)

x < 1 (divide -6 on both sides, flip the sign)
