Answer:

x = 13

Step-by-step explanation:

A linear pair of angles sum to 180° , then

2x + 9 + 10x + 15 = 180 , that is

12x + 24 = 180 ( subtract 24 from both sides )

12x = 156 ( divide both sides by 12 )

x = 13

Answer:

n=-7

Step-by-step explanation:

-234=-38+28

-28n=-38+28n

-28n=196

Since the area of B is 9 times the area of A, we know that the sides of B are √9= 3 times the length of the sides of A.

That's how.

Answer:

b=21

Step-by-step explanation:

P=2(a+b)

54=2(6+b)

54=12+2b

2b+12=54

2b=54-12

2b=42

b=21

6*21 (area)=126

I hope I helped!

How to verify my answer:

P=2(6+21

P=(12+42)

P=54

AHA! So my answer is correct!

Hope I helped!

A relative frequency table is used to display the proportion of variables, in a tabular form.

(a) Draw the Relative Frequency

To do this, we simply divide the frequency of each response by the total frequency.

The total frequency is:

[tex]Total = 326 + 304 + 992 + 257 + 61[/tex]

[tex]Total = 1940[/tex]

So, the calculation of the relative frequency table is as follows:

[tex]Never = \frac{326}{1940}=0.168=16.8\%[/tex]

[tex]Rarely = \frac{304}{1940}=0.157=15.7\%[/tex]

[tex]Sometimes = \frac{992}{1940}=0.511=51.1\%[/tex]

[tex]Most\ times = \frac{257}{1940}=0.132=13.2\%[/tex]

[tex]Always = \frac{61}{1940}=0.031=3.1\%[/tex]

The relative frequency table is:

[tex]\left[\begin{array}{ccc}{Response}&{Frequency}&{Relative\ Frequency}\\Never&326&16.8\%\\Rarely&304&15.7\%&Sometimes&992&51.1\%&Most\ Times&257&13.2\%&Always&61&3.1\%\end{array}\right][/tex]

(b) Percentage that responds always.

From the above calculation, we have:

[tex]Always = 3.1\%[/tex]

Hence, 3.1% responds always

(c) Percentage that responds never or rarely.

From the above calculation, we have:

[tex]Never = 16.8\%[/tex]

[tex]Rarely =15.7\%[/tex]

So, we have:

[tex]Never\ or\ Rarely = Never + Rarely[/tex]

[tex]Never\ or\ Rarely = 16.8\%+ 15.7\%[/tex]

[tex]Never\ or\ Rarely = 32.5\%[/tex]

Hence, 32.5% responds never or rarely.

(d) The frequency bar graph

To do this, we plot the response against the frequency

Answer:

[tex] |4x - 1| = 37 \\ 4x - 1 = + 37 \: \: \: 4x - 1 = - 37 \\ 4x = 38 \: \: \: \: 4x = - 36 \\ x = \frac{19}{2} \: \: \: \: x = - 9 \\ \\ thank \: you[/tex]

Answer:

Step-by-step explanation:

-37 = 4x-1 = 37 (absolute value = negative and positive answer)

-37 = 4x-1

-36 = 4x

-9 = x

4x - 1 = 37

4x = 38

x = 38/4 = 19/2 = 9.5

Answer:

19) x = 48

20) y = 21

Step-by-step explanation:

19)

7x - 248 + x + 44 = 180

(because they're supplementary angles)

8x - 204 = 180

8x = 180 + 204

8x = 384

x = 48

20)

2y + 50 + 5y - 17 = 180

7y + 33 = 180

7y = 180 - 33

7y = 147

y = 21

Answer:

990

Step-by-step explanation:

Hello!

To solve this, you need to distribute and combine like terms.

Like terms are equivalent types of numbers for example;

2x and 3x are like terms, so if the equation said 2x - 5 + 3x, you would only combine 2x and 3x.

If the equation said 5 + 9 - x, you add the like terms, 5 + 9, and the simplification would be 14 - x.

Distribution is when you multiply the number outside the parenthesis into the parenthesis. for example, if an equation says, 5(x-2) = y, you would multiply 5 on the numbers x and -2, resulting in the equation, 5x - 10 = y.

--------Now lets work on your math problem.

Step 1, right the equation, 7(-9a-3)-2a7(−9a−3)−2a

Step 2: distribute numbers (remember multiplying)

7(-9a-3)-2a7(−9a−3)−2a

For the first distribution, 7(-9a-3)-2a7(−9a−3)−2a

you multiply 7 to the numbers in the parenthesis,

resulting in,

-63a - 21

Second distribution is, 7(-9a-3)-2a + 7(−9a−3)−2a

in which you multiply -7 into the numbers in the parenthesis resulting in;

-63a - 21

(did you type the equation twice if so, there are now two problems i need to solve.)

now add like terms -2a + -2a = -4a

-63a - 21 + -63a - 21 = -126a - 42

-126a - 4a - 42

Answer is -130a - 42.

If your equation was actually this, : 7(-9a-3)-2a

Then the answer would have been, -65a - 21

Step-by-step explanation:

2x(5+4)=(_x5)+(_x4)

lets start with 2x(5+4)

(5+4)=9

so we are left with 2x9

2x9=18

so now we have 18=(_x5)+(_x4)

lets try 2 for the blank spaces

18=(2x5)+(2x4)

2x5=10

2x4=8

10+8=18

2x(5+4)=(2x5)+(2x4)

Step-by-step explanation:

my answer is

P=(4,8,12,16,20)

Q=(5,10,15,20)

The set for P and Q will be {4, 8, 12, 16, 20} and {5, 10, 15, 20}, respectively.

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

P = {x:x is a multiple of 4, x ≤ 20}

Then the set for P is given as,

P = 5 {4, 8, 12, 16, 20}

Q = (x:x is a multiple of 5, x ≤ 20 } ​

Then the set for Q is given as,

Q = 4 {5, 10, 15, 20}

Answer:

$180

Step-by-step explanation:

Interest for 1 year = 10% of $300

Interest for 6 years

= (10% × 6) of $300

= 60% of $300

= (60/100) × $300

= 60 × $3

= $180

So, he will earn $180 as interest in 6 years.

Step-by-step explanation:

Absolute value of a number gives the positive quantity of the number.

For instance,

[tex]|3|=3, |-3|=3[/tex]

From this example, therefore we know that

[tex]\text{If }|x|=a,\text{ then }x=a\text{ or } -a. [/tex]

In this question,

[tex]-2|2.2x-3.3|=-6.6[/tex]

[tex]|2.2x-3.3|=3.3[/tex]

[tex]2.2x-3.3=3.3\text{ or } -3.3[/tex]

[tex]2.2x=3.3+3.3 \text{ or }-3.3+3.3[/tex]

[tex]2.2x=6.6\text{ or } 0[/tex]

[tex]x=3\text{ or } 0[/tex]

Answer:

X = 3

Step-by-step explanation:

2(2.2x - 3.3) = 6.6

4.4x - 6.6 = 6.6

4.4x = 6.6 + 6.6

4.4x = 13.2

4.4x = 13.2
