Please help ASAP!!! Christine found a sweater at Nordstrom that was priced at $72.00. She noticed there was a sign that said "All sweaters are 20% off today. How much was the sweater before tax?

a
$57.60

b
$96.40

c
$70.56

d
$56.70

Answer/Step-by-step explanation:

Since ∆PHS ≅ ∆CNF, therefore:

<P ≅ <C,

<H ≅ <N

<S ≅ <F

Thus:

Since, <P ≅ <C, therefore,

36° = (4z - 32)°

36 = 4z - 32

Add 32 to both sides

36 + 32 = 4z

68 = 4z

Divide both sides by 4

68/4 = z

17 = z

z = 17

Since <H ≅ <N, therefore:

6x - 29 = 115°

Add 29 to both sides

6x = 115 + 29

6x = 144

Divide both sides by 6

x = 114/6

x = 24

m<F + m<C + m<N = 180° (sum of ∆)

(3y - 1) + (4z - 32) + 115 = 180 (substitution)

Plug in the value of z and solve for y

3y - 1 + 4(17) - 32 + 115 = 180

3y - 1 + 68 - 32 + 115 = 180

3y + 150 = 180

Subtract 150 from both sides

3y = 180 - 150

3y = 30

y = 10

The value of x, y and z are 24, 10 and 17 respectively.

PHS≅CNF

Therefore,

∠P ≅ ∠C

∠H ≅ ∠N

∠S ≅ ∠F

36 = 4z - 32

36 + 32 = 4z

4z = 68

z = 68 / 4

z = 17

6x - 29 = 115

6x = 115 + 29

x = 144 / 6

x = 24

3y - 1 = 180 - 115 - (4z - 32)

3y - 1 = 180 - 115 - 4z + 32

3y - 1 = 97 - 4(17)

3y - 1 = 29

3y = 30

y = 30 / 3

y = 10

Answer:

Television = $200 and DVD player = $450

Step-by-step explanation:

→ Make 2 equations

Televisions = t and DVD players = d

2t + 3d = 1750

4t + d = 1250

→ Multiply the bottom equation by 3 to make the same variable of d

2t + 3d = 1750

12t + 3d = 3750

→ Minus the two equations to isolate the d variable

-10t = -2000

→ Divide both sides by -10 to find the cost of one television

t = 200

→ Substitute t = 200 back into 4t + d = 1250

800 + d = 1250

→ Minus 800 from both sides to isolate d

d = 450

The total amount of money spend by Mrs.Hopkins on seeds and plants is given by the equation A = $ 16.11

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 equation be represented as A

Now , the value of A is

Let the cost of each tomato plant be = $ 2.59

The number of tomato plant = 4

The cost of 4 tomato plant = 4 x 2.59

The cost of 4 tomato plant = $ 10.36

Now ,

The cost of watermelon seeds = $ 1.87

The cost of adapeno plant = $ 3.88

So , the equation will be

The total amount of money A = cost of 4 tomato plant + cost of watermelon seeds + cost of adapeno plant

Substituting the values in the equation , we get

The total amount of money A = 10.36 + 1.87 + 3.88

The total amount of money A = $ 16.11

Therefore , the value of A is $ 16.11

Hence , the total amount of money is $ 16.11

The solutions to the quadratic equation using the quadratic formula will be:

[tex]x=\frac{1}{2},\:x=\frac{1}{4}[/tex]

Step-by-step explanation:

Given the equation

[tex]8x^2-6x+1=0[/tex]

solving with the quadratic formula

[tex]\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}[/tex]

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\mathrm{For\:}\quad a=8,\:b=-6,\:c=1[/tex]

[tex]x_{1,\:2}=\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:8\cdot \:1}}{2\cdot \:8}[/tex]

as

[tex]\sqrt{\left(-6\right)^2-4\cdot \:8\cdot \:1}=2[/tex]

so

[tex]x_{1,\:2}=\frac{-\left(-6\right)\pm \:2}{2\cdot \:8}[/tex]

Separating the solution

[tex]x_1=\frac{-\left(-6\right)+2}{2\cdot \:8},\:x_2=\frac{-\left(-6\right)-2}{2\cdot \:8}[/tex]

solving

[tex]x_1=\frac{-\left(-6\right)+2}{2\cdot \:\:8}[/tex]

    [tex]=\frac{6+2}{2\cdot \:8}[/tex]

   [tex]=\frac{8}{16}[/tex]

   [tex]=\frac{1}{2}[/tex]

and

[tex]x_2=\frac{-\left(-6\right)-2}{2\cdot \:8}[/tex]

   [tex]=\frac{6-2}{2\cdot \:\:\:8}[/tex]

    [tex]=\frac{4}{16}[/tex]

    [tex]=\frac{1}{4}[/tex]

Therefore, the solutions to the quadratic equation using the quadratic formula will be:

[tex]x=\frac{1}{2},\:x=\frac{1}{4}[/tex]
