Answer:

CD = 38

Step-by-step explanation:

Answer

BC = CD

And,

BC + CD = BD

8x + 8 + 6x - 28 = 10x + 24

14x - 20 = 10x + 24

14x - 10x = 24 + 20

4x = 44

x = 44/4

x = 11

CD = 6(11) - 28

66 - 28

38

Answer:

CD = 38

Step-by-step explanation:

We know that BC and CD will add up to equal BD so we can create a equation and solve for x.

(8x + 8) + (6x - 28) = 10x + 24

~Combine like terms

14x - 20 = 10x + 24

~Add 20 to both sides

14x = 10x + 44

~Subtract 10x to both sides

4x = 44

~Divide 4 to both sides

x = 11

~Now substitute into CD

6(11) - 28

66 - 28

38

MN = [tex]\sqrt{(3 -2)^{2} + (1 - 6)^{2} }[/tex] =[tex]\sqrt{26}[/tex]

Answer:

( t - p ) /  85x =  h

( t - 265.95 ) /  85x  = h

648.45 - 265.95 / 85x = 3.32h

h = 3.32

Therefore ( t - p ) /  85x =  3.32

Step-by-step explanation:

648.45 - 265.95

282.50 /85

= 3.32 hrs

Finding equation to find hours can be shown as

( t - p ) /  85x =  3.32

How we found equation to find total

Parts = 19 x 14 - 5/100 = 266- 0.05

648.45 - 265.95 = 282.5

282.5/85 = 3.323  near to 3,233529

Labour = 85x  = 17 (5 + x)

Equation = 17(5+ x) + 14(19) - 5/100 = 648.45 where x = 85

Equation = ( 85x x 3  1/3) + 265 - 19/20 = t

The repair bill is an illustration of a linear equation. The equation that represents the scenario is: [tex]648.45= 265.95+ 85\times x[/tex]

And the solution (i.e. number of hours) is: 4.5 hours

Given that:

[tex]Bill = 648.45[/tex]

[tex]Parts = 265.95[/tex]

[tex]Labour = \$85[/tex] per hour

Let the number of hours spent be x

So, the equation is:

[tex]Bill = Parts + Labour \times x[/tex]

This gives;

[tex]648.45= 265.95+ 85\times x[/tex]

Collect like terms

[tex]648.45-265.95= 85\times x[/tex]

[tex]382.5= 85\times x[/tex]

Divide both sides by 85

[tex]4.5 =x[/tex]

[tex]x = 4.5[/tex]

Hence, the equation is:

[tex]648.45= 265.95+ 85\times x[/tex]

And the solution (i.e. number of hours) is: 4.5 hours

Step-by-step explanation:

slope = x factor = - 5/2

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

New slope = 2/5 = m

y = mx + b

from the point given y = 2 | x = -4

2 = (2/5 × -4 ) + b

2 = - 1.6 + b

Answer:

I think it may be 52.2 miles

Step-by-step explanation:

The answers to the geometry questions attached are :

5.)

UW = 6x - 35

UW = UV + VW (total length of a line segment)

UV = 19

VW = 4x - 20

6x - 35 = 19 + 4x - 20

6x - 4x = 19 - 20 + 35

2x = 34

x = 34 / 2

x = 17

UW = 6x - 35 = 6(17) - 35 = 67

6.)

HJ = 7x - 27

HJ = HI + IJ (total length of a line segment)

7x - 27 = 3x - 5 + x - 1

7x - 3x - x = - 5 - 1 + 27

3x = 21

x = 21 /3

x = 7

7.)

BD = 7x - 10

BC = 4x - 29

CD = 5x - 9

BD = BC + CD (total length of a line segment)

7x - 10 = 4x - 29 + 5x - 9

7x - 4x - 5x = - 29 - 9 + 10

-2x = - 28

x = 14

BD = 7(14) - 10 = 88

BC = 4(14) - 29 = 27

CD = 5(14) - 9 = 61

Answer:

48 inches

or

0.8 minutes

Step-by-step explanation:

To find the unit rate of inches per hour, divide 144 by 3.

144÷3=48

You don't need to round because there are no decimals.

To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour).

3×60=180

Then divide 144 by 180.

144÷180= 0.8

You don't need to round because there are no thousandths.

Answer:

(-5,8)

Step-by-step explanation:

The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.

Answer:

the answer is the same since it is the same numeral so in terms of y=mx+c and x1/y1 would be inversely proportional to x2/y2 which is perfectly direct proportional to x3/y3×2 and then dy over dx is the problem of integration so you use (x2/x3÷y2/y3)×x1^y1

Step-by-step explanation:

While there are no examples available, there is the room to understand each angle type you listed, vertical angles are angles that are opposite from each other, and they are congruent (they have the same angle in degrees) now, imagine that for vertical angles, they are in an X top and bottom are equal, and the two sides are equal. For a straight angle, that is usually two angles that are right angles (90 degrees) back to back, meaning when you add 90 and 90 degrees together, you get a straight line or a 180 degree angle. An example of an acute angle is any angle less than 90 degrees, that is a real number, so imagine 25, 40, and 60 as all acute angles.

Step-by-step explanation:

if you mean x multiply 2 :

j(x) = 2x + 1

j(a+1) = 2(a+1) + 1

= 2a+ 2 +1

=2a + 3

if you mean x to the power of 2

j(x) = x^2 +1

j(a+1) = (a+1)^2 + 1

= a^2 + 2a + 1 +1

= a^2 + 2a + 2

El kilogramo de harina necesario para hacer 3 1/2 kg de mantequilla para pasteles es 1 2/5 kg

1 kg de mantequilla de bizcocho = 2/5 kg de harina

Deje que la cantidad de kg de harina necesaria para hacer 3 1/2 kg de mantequilla de torta = b

Expresando Matemáticamente:

1 kg = 2/5

1 kg = 2/53 1/2 kg = b

1 = 2/5

3 1/2 = b

Multiplicar en cruz:

b = 3,5 × 0,4

b = 1,4
