Step-by-step explanation:

Answer:

Silk = x = 1.5 yards

Cotton = y = 2.75 yards

Step-by-step explanation:

x + y = 4.25

16.90x + 4y = 36.35

1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.

2.

x + y = 4.25 (1)

16.90x + 4y = 36.35 (2)

Multiply (1) by 4

4x + 4y = 17 (3)

16.90x + 4y = 36.35 (2)

Subtract (3) from (2)

16.90x - 4x = 36.35 - 17

12.90x = 19.35

Divide both sides by 12.90

x = 19.35 / 12.90

= 1.5

x = 1.5 yards

Substitute x = 1.5 yards into (1)

x + y = 4.25

1.5 + y = 4.25

y = 4.25 - 1.5

= 2.75

y = 2.75 yards

Silk = x = 1.5 yards

Cotton = y = 2.75 yards

Answer:

Number 6 is x=65 number 7 is x=-1

Step-by-step explanation:

I just did number 6 on another persons page but ill repeat it as best i can

You're going to set to X plus 2 = 3X -63 then you are going to subtract 2X from both sides which will leave you 2 equals X -63 and then you add 63 to both sides which will leave you x equals 65

Number 7

2X plus 20=6X plus 24

1st Subtract 2X from both sides which will leave you with 20 = 4X plus 24

2nd you're going to subtract 24 from both sides Which will leave you with negative 4 = 4X

Then you're going to divide both sides by 4 which will leave you with X equals negative one

Answer:

What she did wrong, was 6 is a negative number, and she subtracted it like a positive. The real answer is 14

Answer:

44°

Step-by-step explanation:

Because the triangle is isosceles, 4x+20 and 8x-4 would be equal

4x+20 = 8x - 4

4x + 20 - 4x = 8x - 4 - 4x

20 = 4x - 4

20 + 4 = 4x - 4 + 4

24 = 4x

x = 6

m∠EFD = 8x - 4

m∠EFD = 8(6) - 4

m∠EFD = 48 - 4

m∠EFD = 44°

Answer:

7

Step-by-step explanation:

let the no. be 'x'

By question,

2x-8=6

or, 2x =6+8

or,2x = 14

or,x = 7

therefore, the no. is 7.

Answer:

y = 3x - 3

Step-by-step explanation:

y = mx + b

m = slope

slope = y2 - y1/x2 - x1

slope = 6 - 3/3 - 2

slope = 3/1

slope = 3

y = 3x + b

b = y-intercept

y-intercept is y when x = 0

rise over run

If slope = 3/1, then subtract 3 from y and 1 from x until x = 0

(2, 3) = 3/2

3 - 3/2 - 1 = 0/1 = (1, 0)

0 - 3/1- 1 = -3/0 = (0, -3)

x = 0

y-intercept = -3

y = 3x + - 3

negative + positive = negative

y = 3x - 3

Answer:

$ 226.56

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 12.8%/100 = 0.128 per year,

then, solving our equation

I = 590 × 0.128 × 3 = 226.56

I = $ 226.56

The simple interest accumulated

on a principal of $ 590.00

at a rate of 12.8% per year

for 3 years is $ 226.56.

590 · 12.8% = 590 · .128 = 75.52

75.52 · 3 = 226.56

Answer:

c = 18n + 7

Step-by-step explanation:

Given the following data;

Total cost is represented by c

Number of uniforms ordered is represented by n

Shipping fee = $7

Cost per uniform = $18

The total cost is equal to the amount of money spent on ordering each uniform ($18) plus the shipping costs ($7).

Translating the word expression into an algebraic equation, we have;

c = 18n + 7

For example, if Dontina is ordering 10 uniforms for her employees.

n = 10

Substituting the value of n into the equation, we have;

c = 18(10) + 7

c = 180 + 7

c = $187

Therefore, the total cost incurred by Dontina in ordering 10 uniforms for her employees is $187.

Answer:

2x-6

Step-by-step explanation:

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 4 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (1, 1) into the partial equation

1 = 2 + c ⇒ c = 1 - 2 = - 1

y = 2x - 1 ← equation of parallel line

Answer:

1) The reason, the 210° angle is not used is because, the values of the trigonometric ratios for 210° is the same as the values of the trigonometric ratios for 30°

2) The two equations used to set up the problem are;

The y-coordinate value, y₁ = -40×sin(30°) = -20 feet

The x-coordinate value, x₁ = 40×cos(30°) = 34.64 feet

3) The coordinates of the point location of Jack's seat = (20×√3, -20)

Step-by-step explanation:

The given information are;

The diameter of the carousel = 80 feet

The rotation of the carousel = 210°

Assuming Jack seat was initially on the left side of the center of the carousel and the carousel rotates clockwise, we have;

Final position of the carousel = 210 - 180 = 30° South of East

The radius of the carousel = (80 feet)/2 = 40 feet

The slope of the location of Jack seat = -tan(30°)

The y-intercept = The center = 0

y - y₁ = m·(x - x₁)

The y-coordinate value, y₁ = -40×sin(30°) = -20 feet

The x-coordinate value, x₁ = 40×cos(30°) = 20×√3 = 34.64 feet

The equation in point and slope form is therefore;

y - (-20) = -√3/3×(x -  34.64)

y + 20 = -x·√3/3 + 20

y = -x·√3/3

The reason, the 210° angle is not used is because, the values of the trigonometric ratios for 210° is the same as the values of the trigonometric ratios for 30°

The two equations used to set up the problem are;

The y-coordinate value, y₁ = -40×sin(30°) = -20 feet

The x-coordinate value, x₁ = 40×cos(30°) = 34.64 feet

The coordinates of the point location of Jack's seat = (20×√3, -20)

Answer:

Step-by-step explanation:

Given function

This is quadratic function  

It reaches the maximum value at vertex, which is calculated by the formula:

Substituting values

y-value of same point is

So maximum height is 294.3 ft

The equation we have is:

[tex]y = { - 16x}^{2 } + 119x + 73[/tex]

This is equation of a parabola that opens down.

To find the maximum point or the maximum height, we need to find the vertex of the parabola.

First, let's define variables:

A will be the coefficient of the x squared.

b is the coefficient of the x and

C is the independent term:

[tex]a = - 16 \\ b = 119 \\ c = 73[/tex]

The vertex of will have the following x coordinate:

[tex]x = - \frac{b}{2a} [/tex]

Substituting the values of a and b:

[tex]x = - \frac{119}{2( - 16)} [/tex]

Solving the operations:

[tex]x = - \frac{119}{ - 32 } \\ x = 3.71875[/tex]

The next step is to substitute this x value into our equation to find the maximum height y:

[tex]y = { - 16x}^{2} + 119x + 73 \\ \\ substituting \: x = 3.71875 \\ \\ y = - 16(3.71875)^{2} + 119(3.71875) + 73[/tex]

Solving the operations:

[tex]y = - 16(13.8291) + 442.49555 + 73 \\ \\ y = 294.23[/tex]

Rounding to the nearest tenth (1 decimal place)

y=294.2

Answer: 294.2 feet.

Answer:

x= -16

Step-by-step explanation:

distribute -2

-2 * 2x =-4x

-2 * 5 = -10

-4x - 10 -3 = -3 (x-1)

distribute -3

-3 * x = -3x

-3 * -1 = 3

-4x - 10 -3 = -3x + 3

combine like terms

-4x -13 = -3x + 3

-4x + 3x = -x

3 + 13 = 16

-x = 16

divide by -1

x = -16

Answer:

x = -16

Step-by-step explanation:

-2(2x + 5) - 3 = -3(x - 1)

-4x - 10 - 3 = -3x + 3

-4x - 13 = -3x + 3

-x = 16

x = -16   <--- This is the answer

Answer:

m = [tex]\frac{pz+2n}{2}[/tex]

Step-by-step explanation:

Given

2(m - n) = pz ← distribute parenthesis on left side

2m - 2n = pz ( add 2n to both sides )

2m = pz + 2n ( divide both sides by 2 )

m = [tex]\frac{pz+2n}{2}[/tex]
