Answers

Answer 1

Answer:

1 solution

Step-by-step explanation:

Given

- 3n = - 10 - 2n ( add 2n to both sides )

- n = - 10 ( multiply both sides by - 1 )

n = 10

Answers

Answer:

16.8

Step-by-step explanation:

you get this by taking the ratio of 12:30 and applying it to 42

you get 30 by taking the total of 12 + 18

you then divide 12 / 30 which equals 0.4

you then multiply 0.4 * 42 which gives you 16.8

if you were to solve for the other ratio you would divide 18 / 30

and then take the answer of that, 0.6 and multiply it by 0.6 * 42

then you have the other part of the ratio.

Answer:

  1) W = 10

  2) x = 33/2

Step-by-step explanation:

These are 2-step linear equations. Step 1: Add the opposite of the constant on the right. Step 2: Divide by the coefficient of the variable.

__

1) 15 = 2W -5

  20 = 2W . . . . . add +5

  10 = W . . . . . . . divide by 2

__

2) 24 = 2x -9

  33 = 2x . . . . . add +9

  33/2 = x . . . . divide by 2

_____

As always, whatever you do to one side of the equation must also be done to the other side. That is, the same number is added to both sides; both sides are divided by the same number.

The LCM of 4 and 7 is 28

Step-by-step explanation:

LCM is the lowest common multiple of two or more numbers.

To find it do that:

List the multiples of each numberFind the first common multiple of them, it will be the LCM

Let us find the lowest common multiple of 4 and 7

→ List the multiples of 4

∵ The multiples of 4 are, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, .......

→ List the multiples of 7

∵ The multiples of 7 are, 7, 14, 21, 28, 35, 42, 49, .........

→ Find the first common multiple of 4 and 7

∵ 28 is the first common multiple of 4 and 7

∴ The lowest common multiple of 4 and 7 is 28

∴ The LCM of 4 and 7 is 28

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 = 3 parts

Divide 36 by 3 to find the value of one part of the ratio.

36 ÷ 3 = 12 ← value of 1 part of the ratio , thus

2 parts = 2 × 12 = 24

Thus

36 in the ratio 1 : 2 is 12 : 24

The values for x are:

question 15 ⇒x=8

question 16⇒x=19

question 17⇒x=14

Here you should apply your knowledge about regular polygons. The question asks the values of x that is a variable for some interior angles. Then, you will find x from the sum of interior angles of each regular polygon.

Sum of Interior Angles of Regular Polygon

There is a formula that relates number of sides polygon with its sum of interior angles. See below.

                                 S=(n-2)*180°

S=sum of interior angles of regular polygon.

n=number of sides of regular polygon.

Exercise 15

First, you should find the value for the sum of interior angles. Here, the regular polygon has 4 sides. Then,

                                 S=(n-2)*180°

                                 S=(4-2)*180°

                                 S=2*180°=360°

Note that only 3 interior angles are shown in the figure. Nonetheless, the question gives an external angle (71°). Thus, the internal angle will be: 180-71=109°. This is because the interior and exterior angles are supplementary.

Next step, sum of interior angles for finding x

                                  [tex]10x+6+13x-2+109+8x-1=360\\ \\ 31x=360-112\\ \\ 31x=248\\ \\ x=\frac{248}{31} =8[/tex]

                                      x=8

Exercise 16

First, you should find the value for the sum of interior angles. Here, the regular polygon has 6 sides. Then,

                                 S=(n-2)*180°

                                 S=(6-2)*180°

                                 S=4*180°=720°

Next step, sum of interior angles for finding x.

                   [tex]90+9x-19+7x+3+111+5x+8+128=720\\ \\ 21x=720-321\\ \\ 21x=399\\ \\ x=\frac{399}{21} =19[/tex]

                   x=19

Exercise 17

First, you should find the value for the sum of interior angles. Here, the regular polygon has 5 sides. Then,

                                 S=(n-2)*180°

                                 S=(5-2)*180°

                                 S=3*180°=540°

The image of the question shows the sides are congruent, consequently, the angles are equal.

Next step, sum of interior angles for finding x.

                    [tex]9x-18+9x-18+9x-18+9x-18+9x-18=540\\ \\ 45x=540+90\\ \\ 45x=630\\ \\ x=\frac{630}{45} =14[/tex]

                     x=14
