Point N is between M and R. If MN = 25 in, and NR = 12 in, then what is the length of MR?

Answer:

$0.06(x)=$45.84

Step-by-step explanation:

x= the number of hours used

x=764 hours

to get the 764 you divide 45.85/0.06 because you want to isolate the variable.

Answer:

$0.06(x)=$45.84

Answer:

Step-by-step explanation:

From the problem statement, from the score which is given as  15._66.

it is only one digit that is missing and not a combination of two digits.

This makes our guess easier as we have a range of 0-9 to guess from

therefore the list of possible digits to select from can be given as

from between 0-9 which is

{0,1,2,3,4,5,6,7,8,9}

Answer:

A. (x+12)(x-12)

Step-by-step explanation:

Use foil method

x * x = x^2

x * - 12 = - 12x

12 * x = 12 x

12 * - 12 = - 144

x^2 [- 12x + 12x= 0x = 0] - 144

x^2 + 0 - 144 =

x^2 - 144 #

Answer:

What are the factors of x2 – 144?

✔ (x – 12)

 and

✔ (x + 12)

Step-by-step explanation:

Total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.

"Total cost is defined as the sum of all the expenses which is required to produce a product."

According to the question,

C=total cost,

h= hour of labor

p = additional charges for parts

Total cost given as

C= 45 +20h + p

h = 4hour

p = $109

Substitute the value in the total cost we get,

C = 45+20(4) +109

   =$229

Hence, total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.

To determine which ratio would result in a valid proportion when set equal to StartFraction 7 over 3 EndFraction, we need to find the ratio that is equivalent to StartFraction 7 over 3 EndFraction.

To do this, we can cross-multiply. When we cross-multiply StartFraction 7 over 3 EndFraction and another ratio, the product of the numerator of StartFraction 7 over 3 EndFraction and the denominator of the other ratio should be equal to the product of the denominator of StartFraction 7 over 3 EndFraction and the numerator of the other ratio.

Let's check each option:

1. StartFraction 9 over 49 EndFraction:

7 x 49 = 343

3 x 9 = 27

These values are not equal, so it is not a valid proportion.

2. StartFraction 18 over 42 EndFraction:

7 x 42 = 294

3 x 18 = 54

These values are not equal, so it is not a valid proportion.

3. StartFraction 42 over 18 EndFraction:

7 x 18 = 126

3 x 42 = 126

These values are equal, so it is a valid proportion.

4. StartFraction 49 over 9 EndFraction:

7 x 9 = 63

3 x 49 = 147

These values are not equal, so it is not a valid proportion.

Therefore, the ratio that results in a valid proportion when set equal to StartFraction 7 over 3 EndFraction is StartFraction 42 over 18 EndFraction.

Explanation:

Triangle ABC is isosceles because AC = BC.

The angles opposite these congruent sides are angle ABC and angle BAC. These are the base angles.

For any isosceles triangle, the base angles are congruent.

Angle BAC = 69 degrees is given. So angle ABC = 69 as well.

-------------------

The missing angle must add to the two other angles so that all three angles in a triangle add to 180

(angle ABC) + (angle BAC) + (angle BCA) = 180

69 + 69 + (angle BCA) = 180

138 + (angle BCA) = 180

angle BCA = 180-138

angle BCA = 42

-------------------

Angle DCE is congruent to angle BCA because they are vertical angles.

Triangle DCE is a right triangle. The missing angle is 90-(angle BCA) = 90-42 = 48

angle EDC = 48 degrees

Answer: (a) ([tex]x_{2},y_{2}[/tex]) = (3,2)

              (b)  ([tex]x_{2},y_{2}[/tex]) = (19,-7)

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

[tex]x_{m}=\frac{x_{1}+x_{2}}{2}[/tex]

[tex]y_{m}=\frac{y_{1}+y_{2}}{2}[/tex]

Isolating [tex]x_{2}[/tex]:

[tex]2x_{m}=x_{1}+x_{2}[/tex]

[tex]x_{2}=2x_{m}-x_{1}[/tex]

And [tex]y_{2}[/tex]:

[tex]2y_{m}=y_{1}+y_{2}[/tex]

[tex]y_{2}=2y_{m}-y_{1}[/tex]

(a) Replacing values and calculating [tex]x_{2}[/tex]:

[tex]x_{2}=(2*2)-1[/tex]

[tex]x_{2}=3[/tex]

Calculating [tex]y_{2}[/tex]:

[tex]y_{2}=[2*(-1)]-(-4)[/tex]

[tex]y_{2}=2[/tex]

D

Answer:

0

Step-by-step explanation:

First of all, simplify the equation on both sides. You will get 5x - 2 = 2x - 2. Add two to both sides, and you get 5x=2x. Subtract 2x from both sides to get 3x=0, so x will equal 0.

Answer:

5x = 2x

5x- 2 = 2 + 2x

5x - 2+ 2 = -2 + 2x +2

Explanation:

Based on the diagram, angles L and X are the top most angles. They correspond to have angle L = angle X = 60 degrees

Though you shouldn't rely solely on a diagram because the figures may be oriented in a strange way. A better way is to look at the letter sequences of JKLMN and VWXYZ

Notice how L and X are the third letters of JKLMN and VWXYZ respectively. This means the letters pair up and are congruent angles (since the polygons are similar). So this is a non-visual way to see how angle L = angle X = 60.
