|4 - 2x| = |3x + 2|

First subtract 2 from each side

|4 - 2x| = |3x|

Then add 2x to each side

|4| = |5x|

Divide both sides by 5

0.8 = x

Points A,M and P are collinear with M in between A and P. If AP=29, AM =5x-3 and MP=8x+6, what does MP=?
charle [14.2K]

The length of MP is 22 units.

<h3>What is a Line Segment?</h3>

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure is given below shows a line segment AP, where the length of line segment AP refers to the distance between its endpoints, A and P.

Given that Points A, M and P are collinear with M in between A and P.

AP=29, AM =5x-3 and MP=8x+6,

A______________M______________P

⇒ AP = AM + MP

Substitute the values of AP = 29, AM =5x-3 and MP=8x+6,

⇒ 29 = 5x - 3 + 8x+6,

Rearranging the terms in the above equation,

⇒ 5x + 8x = 29 + 3 - 6

⇒ 13x = 26,

⇒ x = 26/13,

⇒ x = 2

So MP = 8x+6

Substitute the value of x = 2 in the above equation,

⇒ MP = 8(2) + 6

⇒ MP = 22

Hence, the length of MP is 22 units.

A coin bank contains only quarters and dimes. The total value of the coins in the bank is $8.80. If the dimes were quarters and
masha68 [24]

Answer:

  • 18 dimes

Step-by-step explanation:

Let the number of dimes be d and quarters be q

<u>The value is $8.80 = 880¢, so:</u>

  • 10d + 25q = 880 ⇒ 2d + 5q = 176

<u>If the dimes were quarters and the quarters were dimes, the coins' total value would be $7.30 or 730¢</u>

  • 25d + 10q = 730 ⇒ 5d + 2q = 146

<u>Now we have 2 equations. Solving the system by elimination, subtract 5 times the second equation from twice the first equation:</u>

  • 2(2d + 5q) - 5(5d + 2q) = 2(176) - 5(146)
  • 4d - 25d = -378
  • -21d = -378
  • d = -378/-21
  • d = 18

ASAP:::::: 75 POINTS TO THE BRAINLIEST!!!!!
Misha Larkins [42]

Answer:

t = 6 4/25 hours

Step-by-step explanation:

The formula to find out how long it takes them to do the job is

1/m  + 1/ a  = 1 /t

where m is the time for Matthew to do the job

a is the time for Arianna to do the job

and t is the time for them to do the job together

m = 14 hours

a = 11 hours

Substituting what we know

1/14 + 1/11 = 1/t

Multiplying by 154t (14*11*t) so we can clear the fractions

154t*(1/14 + 1/11) = 1/t* 154t

 11t + 14t = 154

Combine like terms

25t = 154

Divide by 25

t = 154/25

t = 6 4/25 hours
