¿Alguien sabe como realizarlo?

Answer:

1

Step-by-step explanation:

4(4-w) = 3(2w+2)

Use distributive property:

16 - 4w = 6w + 6

    +4w  +4w

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

     16 = 10w + 6

    -6              -6

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

        10 = 10w

        ----    -----

        10      10

         1 = w

Hope this helped.

Hence, the required answer is 1

Step-by-step explanation:

Add 67% of 85 to 33% of 76:

67% of 85

[tex]\\ \sf\longmapsto \dfrac{67}{100}\times 85[/tex]

[tex]\\ \sf\longmapsto 85(0.67)[/tex]

[tex]\\ \sf\longmapsto 56.95[/tex]

33% of 76

[tex]\\ \sf\longmapsto \dfrac{33}{100}\times 76[/tex]

[tex]\\ \sf\longmapsto 76(0.33)[/tex]

[tex]\\ \sf\longmapsto 25.08[/tex]

Add both

[tex]\\ \sf\longmapsto 56.95+25.08[/tex]

[tex]\\ \sf\longmapsto 82.03[/tex]

Answer:

32.

Step-by-step explanation:

Here is the equation I used. (x = hours)

$400 = $12.50x

To find how many hours he needs to work, divide both sides by 12.50 to get x by itself.

400/12.50 = 12.50x/12.50

Which equals:

32 = x

Step-by-step explanation:

We are dealing with theoretical probability. This means that our probability of said outcome is

[tex] \frac{x}{y} [/tex]

where x is the outcome we want, and y is the total number of outcomes possible.

28. There is 3 triangles out of 6 polygons so the probability is 1/2.

29.There is 1 Pentagon so the probability is 1/6.

30. This is a complement to question 28. A complement is the inverse of the problem. A complement and its original add to 1 so the probability of both getting a triangle is 1/2.

31. There is 4 non quadraletrial so the probability is 2/3.

32. There is 3 figures that has more sides than three so 1/2 is the probability.

33.There is only multi right angles figures so 1/2 is the probability.

34. There is 30 days in April so the probability it's the 29th is

[tex] \frac{1}{30} [/tex]

35. There is 31 days in July and 15 days after the 16th. So the probability

is

[tex] \frac{15}{31} [/tex]

Answer:A

Step-by-step explanation:

We have with a  study the diagram of the diagram below and the explanations that follows the correct answers are

Generally

1)

OP is a segment bisector.

NO

OP is not a segment bisector because it those not divide segment LKMN in to two equal parts.

2)

OP is a perpendicular bisector.

NO

OP is not a perpendicular bisector because a perpendicular bisector is a bisector that cuts a segment into two equal parts and create an angle to the normal

3)

OP is an angle bisector

NO.

Because OP those not divide any angles into two equal parts

4)

O is the vertex of a pair of congruent angles in the diagram.

YES

Because O lines in between two angles of the same degree()

5)

O is the vertex of a right angle.

NO

Because O those not exist at a right angle

6)

The midpoint of a segment in the diagram

The mid point of this segment can be derived by drawing diagonals across the 4 vertex LMNK.

Answer:

18

Step-by-step explanation:

2h - 32 - 16 = -12

2h - 48= -12

2h =-12+48

h=36\2

h = 18

Answer:

h = 18

Step-by-step explanation:

Given

2(h - 16) - 16 = - 12 ← distribute and simplify left side

2h - 32 - 16 = - 12

2h - 48 = - 12 ( add 48 to both sides )

2h = 36 ( divide both sides by 2 )

h = 18

Answer:

BC = 7

Step-by-step explanation:

AB + BC = AC

Substitute values for the line segments:

6 + BC = 13

Isolate line segment BC by subtracting both sides by 6:

6 - 6 + BC = 13 - 6

0 + BC = 13 - 6

BC = 7

Check your work:

6 + 7 = 13

13 = 13

Answer:

5 and 1/4 hours or 5 hours and 15 minutes

Step-by-step explanation:

She played her flute 3/4 hours every day for 7 days, so to find the total number of hours we can multiply 3/4 by 7 to get 21/4.  This is equal to 5 and 1/4 hours, or 5 hours and 15 minutes.

Answer:  5.25 hrs

Step-by-step explanation:  3/4 of an hour is 45 min.  45 min x 7 days is 315 min which is 5 hours and 15 min or 5.25 hrs
