Answers

Answer 1

Answer:

the number is (((6))))

Answer 2

Answer:

The answer is 6

Step-by-step explanation:

What wanna start out with finding the difference by subtracting 10 from 22. This would give you the difference of 12. Since its 'double the number', we are going to find the quotient of 12 / 2 = 6. You will then end up with the answer 6.

Answers

Answer:

your answer would be  t=-1 or t=1

Step-by-step explanation:

-(2t-3) = 3t-2

Multiply

     -2t+3 = 3t-2

Rearrange and Add up

     -5t = -5

Divide both sides by 5

-t = -1

Multiply both sides by (-1)

t = 1

Which is the solution for the Negative Case

Solve the Positive Case

     (2t-3) = 3t-2

Rearrange and Add up

     -t = 1

Multiply both sides by (-1)

     t = -1

What is the coordinate of the midpoint of DA?
D

Answers

Answer:

6

Step-by-step explanation:

Coordinate of point D = -6

Coordinate of point A = 18

The coordinate of the midpoint of DA = the coordinate of the point that is half the distance from D to A.

Distance of DA = |18 -(-6)| = |18 + 6| = 24

Midpoint = ½ the distance of DA = ½*24 = 12

Coordinate of the midpoint of DA = coordinate of D + 12 = -6 + 12 = 6

Or,

Coordinate of A - 12 = 18 - 12 = 6

Therefore, coordinate of the midpoint of DA = 6.

MO bisects LMN mLMN = 8x-23 and mLMO= 2x+37 solve for x and find LMN

Answers

Answer:

see explanation

Step-by-step explanation:

Since MO bisects ∠ LMN then

∠ LMO and ∠ NM0 are congruent, thus

∠ LMN = ∠ LMO + ∠ NMO , substitute values

8x - 23 = 2x + 37 + 2x + 37 = 4x + 74 ( subtract 4x from both sides )

4x - 23 = 74 ( add 23 to both sides )

4x = 97 ( divide both sides by 4 )

x = 24.25

Thus

∠ LMN = 8x - 23 = 8(24.25) - 23 = 194 - 23 = 171°

The sum of two numbers is 50. The first number is 18 less than the 2nd number. What are the
2 numbers?

Answers

Answer:

2y + 2 + y = 50 (combine like terms)

3y + 2 = 50

3y = 50 - 2

3y = 48

y = 16

Substitute 16 for y in either equation 1 or 2 and solve for x (I chose equation 1):

x + 16 = 50

x = 50 - 16

x = 34

To solve for x, you want to use algebraic properties to isolate x.

[tex]\frac{x}{4}=2+\frac{x-3}{3}[/tex]                       [subtract both sides by [tex]\frac{x-3}{3}[/tex]]

[tex]\frac{x}{4}-\frac{x-3}{3}=2[/tex]                       [get common denominator]

[tex]\frac{3x}{12} -\frac{4x-12}{12} =2[/tex]                  [subtract]

[tex]\frac{-x+12}{12} =2[/tex]                          [multiply both sides by 12]

[tex]-x+12=24[/tex]                     [subtract both sides by 12]

a^2 + b^2 = c^2

x^2 + 24^2 = ( 12+x)^2

FOIL the right side

x^2 +576 = 144 + 24x + x^2

Subtract x^2 from each side

576 = 144 + 24x

Subtract 144 from each side

576-144 = 24x

432 = 24x

Divide each side by 24
