Answer:

See below ↓

Step-by-step explanation:

19.

  • \frac{x-1}{2} - \frac{x-3}{5} - \frac{x-7}{10} + \frac{x-2}{5}
  • \frac{5(x-1)-2(x-3)-(x-7)+2(x-2)}{10}
  • \frac{5x-5-2x+6-x+7+2x-4}{10}
  • \frac{4x+4}{10}
  • \frac{2x+2}{5}

20.

  • \frac{2x+3}{2x} + \frac{x+3}{4x} - \frac{18x+6}{8x^{2} }
  • \frac{4x(2x+3)+2x(x+3)-(18x+6)}{8x^{2} }
  • \frac{8x^{2} +12x+2x^{2} +6x-18x-6}{8x^{2} }
  • \frac{10x^{2}-6}{8x^{2} }
  • \frac{5x^{2}-3}{4x^{2} }

Vincent and Aidan buy the same number of pens. Vincent buys packs of 6 pens, and Aidan buys boxes of 20 pens. What is the least
Shtirlitz [24]

The least number of pens each boy can have brought is 60

<h3>How to determine the least number of pen?</h3>

We have:

Vincent = 6 packs

Aidan = 20 boxes

Factorize 6 and 20

6 = 1 * 2 * 3

20 = 1 * 2 * 2 * 5

Multiply all factors

LCM = 1 * 2 * 2 * 3 * 5

Evaluate the product

LCM = 60

Hence, the least number of pens each boy can have brought is 60

How does the graph of f(x)=3|x+2|+4 relate to its parent function
Mariana [72]
If parent functin is f(x)=|x|
it is moved to the left 2 units
vertically streched by a factor of 3
and moved up by 4 units in that order

because
to move a function to left c units, add c to every x
to vertically strech function by factor of c, multiply whole function by c
to move funciotn up c units, add c to whole function


so it is 2 to the left, verteically streched by a factor of 3 then moved up 4 units

Anarel [89]

Answer:

17

Step-by-step explanation:

If it costs $20 for the membership fee, then you can subtract that from the total monthly cost, giving you $25.50.

Then, you can divide this number by the price of each song to work out how many songs you downloaded, because you are simply rearranging the formula to work out the total price. $25.50 / $1.50 = 17.

Answer:

  • The are congruent.
  • They are non-adjacent.

Step-by-step explanation:

Where a transversal crosses parallel lines, the angles outside the parallel lines are called exterior angles. When they are on opposite sides of the transversal, they are <em>alternate exterior angles</em>.

Alternate exterior angles are congruent.

The share a side (the transversal, but not a vertex. So they are non-adjacent.

_____

<em>Additional comment</em>

In this geometry, <em>corresponding</em> angles are congruent. Of course, vertical angles are always congruent. Each alternate exterior angle is a vertical angle with one that is corresponding to the other alternate exterior angle.
