Forty percent of the first 20 whole numbers are prime. How many of the first 20 whole numbers are prime?

Answer:

[tex]\boxed {x = -2}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]3x + 6 = -3(2x + 4)[/tex]

-Use Distributive Property:

[tex]3x + 6 = -3(2x + 4)[/tex]

[tex]3x + 6 = -6x - 12[/tex]

-Take [tex]6x[/tex] and add it to [tex]3x[/tex]:

[tex]3x + 6 + 6x = -6x + 6x - 12[/tex]

[tex]9x + 6 = -12[/tex]

-Subtract both sides by [tex]6[/tex]:

[tex]9x + 6 - 6 = -12 - 6[/tex]

[tex]9x = -18[/tex]

-Divide both sides by [tex]9[/tex]:

[tex]\frac{9x}{9} = \frac{-18}{9}[/tex]

[tex]\boxed {x = -2}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-2[/tex].

Answer:

- 6 13/18

Step-by-step explanation:

5/9 times -4 is -20 over 9     -20/9     -2 2/9

3/4 times -6 is -18 over 4     -18/4         -4 1/2

You need them to have a common denominator

so you can multiply the first answer by 4 and the second by 9.

You get -242/36 after a while

and then

you simplify.

You can multiply 36 six times  into -242 so you get the whole number of 6 plus 216

242-216 is 26

26 over 36 is 13 over 18

-6 13/18

Just add it up on a calculator and that's for the terms. t = 11.50

Answer:

x = 7.5

y = 14

m<1 = 87°

m<7 = 93°

Step-by-step explanation:

Given:

m<2 = (14x - 12),

m<6 = (5y + 23),

m<8 = (8x + 27)

m<2 + m<8 = 180° (consecutive exterior angles are supplementary)

(14x - 12) + (8x + 27) = 180 (substitution)

Solve for x

14x - 12 + 8x + 27 = 180

Collect like terms

22x + 15 = 180

Subtract 15 from each side

22x = 180 - 15

22x = 165

Divide both sides by 22

x = 7.5

m<2 = m<6 (corresponding angles are congruent)

(14x - 12) = (5y + 23) (substitution)

Plug in the value of x

14(7.5) - 12 = 5y + 23

105 - 12 = 5y + 23

93 = 5y + 23

Subtract 23 from each side

93 - 23 = 5y

70 = 5y

Divide both sides by 5

14 = y

y = 14

✅m<1 = m<8 (alternate exterior angles are congruent)

m<1 = (8x + 27) (substitution)

Plug in the value of x

m<1 = 8(7.5) + 27 = 87°

m<7 = m<2 (alternate exterior angles are congruent)

m<7 = (14x - 12) (substitution)

Plug in the value of x

m<7 = 14(7.5) - 12 = 93°

Answer:

Maybe its 41?

What is the question?

Answer:

Answer is A

Step-by-step explanation:

(x,y) → (x + 2, y - 8)

when moving to the right 2 the x coordinate increases by two when moving down 8 the y coordinate decreases by eight

Answer:

Option (C)

Option (C)

Option (A)

Step-by-step explanation:

Part A.

Frank's walking speed can be represented by the equation.

Equation representing the speed is,

y = 85x

[tex]\frac{y}{x}=85[/tex]

Therefore, walking speed of Frank = 85 meters per minute.

Option (C) will be the answer.

Part B.

Distance walked over the time by Jeffrey is given by the graph attached.

Equation for the speed will be,

y = [tex](\frac{400}{5})x[/tex]

y = 80x

Therefore, walking speed of Jeffrey = 80 meters per minute

Difference in the speed of Frank and Jeffrey = 85 - 80 = 5 meters per minute.

Jeffery walks 5 meters per minute slower than Frank.

Option (C) will be the answer.

Part (C)

Distance traveled by Frank in 16 minutes,

y = 85(16) = 1360 meters

Time taken to travel the same distance by Jeffrey will be,

1360 = 80x

x = [tex]\frac{1360}{80}=17[/tex] meters per minute

Option (A) will be the answer.

Answer:

You would draw a sloped line leaning to the right, then make it less steep, then draw a flat line.

Explanation:

The steeper slope represents the dog walking at a normal pace, when the line gets a little less steep it means the dog has slowed down, and when it is flat is where ethe dog took a rest.

Now let me give you an example problem, followed by PEMDAS

5(11-1+7-2)

First we solve within the parenthesis

1) Add, as thats what we see first

Answer:

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. (It's the number that's with the variable)

Step-by-step explanation:

4x-7=5

Coefficient: 4

Answer:

1. 10

2. 10

3. 12

4. [tex]3\sqrt{14}[/tex] or 11.22497216

Step-by-step explanation:

1.  [tex]a^{2}+b^{2} =c^{2}\\\\a^{2} = 8^{2} = 64\\b^{2} = 6^{2} = 36\\c^{2} = a^{2} + b^{2} = 64 + 36 = 100\\c = \sqrt{100} = 10[/tex]

2. [tex]c^{2}-a^{2} =b^{2}\\\\a^{2} = 24^{2} = 576\\c^{2} = 26^{2} = 676\\b^{2} = c^{2} - a^{2} = 676 - 576 = 100\\b = \sqrt{100} = 10[/tex]

3.[tex]c^{2}-a^{2} =b^{2}\\\\a^{2} = 5^{2} = 25\\c^{2} = 13^{2} = 169\\b^{2} = c^{2} - a^{2} = 169 - 25 = 144\\b = \sqrt{144} = 12[/tex]

4. [tex]c^{2}-b^{2}=a^{2}\\\\b^{2} = 11^{2} = 121\\c^{2} = \sqrt{137}^{2} = 137\\a^{2} = c^{2} - b^{2} = 137 - 11 = 126\\a = \sqrt{126} = 3\sqrt{14} = 11.22497216[/tex]

Answer:

It is a not a Function.

Because one number has two arrows pointing to two different numbers.

Answer:

No

Step-by-step explanation:

(the image is fuzzy so you can't really see the lines)

It seems that when x = 1, f(x) is both 4 and 5.

While two different x values can equal the same y value, one single x value cannot be equal to more than one value.

If this was a function that could be graph, there would be an extra dot at (1, 4) or (1, 5) since 1 is equal 4 or 5. This is why it is not a function.
