anyone know this , please help

Answer:

Answer -   -5

Step-by-step explanation:

Answer:

The correct answer is 2

Answer:

3

Step-by-step explanation:

combine like terms (so 1/2 and 3/2): 2 - x = x - 4

add x to both sides: 2 = 2x - 4

add 4 to both sides: 6 = 2x

divide both sides by 2: 3 = x

Answer:

x= -0.5

Step-by-step explanation:

You want to isolate x on one side of the equation

15-12x=21

-15          -15

-12x=6

/-12     /-12

x= -0.5

Answer:

  12/11 = 1 1/11 hours

Step-by-step explanation:

The total rate is the sum of the individual rates in rooms per hour.

Tom can paint 1/4 room per hour.

Sam and Victor can each paint 1/3 room per hour.

Their total rate is ...

  1/4 +1/3 +1/3 = 11/12 . . . rooms per hour

The rate in "hours per room" is the inverse of this.

It takes them 12/11 = 1 1/11 hours to paint one room.

Answer:

corresponding angles

Alternate angle

cointerior angle

Now , For 12n to end with 0, it should have 2 as well as 5 in its Prime factors to end with 0, Also to end with 5 , it requires at least a single multiple of 5 in its Prime Factors, So 12n cannot end with the digit 0 or 5.

3x - y = 8

Step-by-step explanation:

Since, if a line having points represented by (x,y) is dilated about origin with a scale factor k,

Then the coordinates of the dilated line is obtained by the rule,

Here, line L is,

3x - y = 4

The x-intercept and y-intercept of line L are (4/3,0) and (0,-4) respectively,

If the line L is mapped onto line M by a dilation centered at the origin with a scale factor of 2,

Then by the above definition,

The points of the line M are,

(2×4/3, 2×0) and (2×0, 2×-4) ⇒ (8/3,0) and (0,-8)

Hence, the equation of line M passes through the points (8/3,0) and (0,-8)

Answer:

The better buy is the 16 ounce package for $5.28.

Step-by-step explanation:

First divide each price with their ounce,so 2.10 ÷ 6 = 2.1 per 1 ounce , 5.28 ÷ 16 = 0.33 per 1 ounce , 9.35 ÷ 26 = 0.36 per 1 ounce.

Next compare the prices for 1 ounce and see which on is lower. The 16 ounce package has a better price because the price for each ounce is lower than the other prices.

Answer:

a = 150

Step-by-step explanation:

The sum of the internal angles of an octagon is 1080°.

[tex]4a+4(120)=1080[/tex] (There are four [tex]120^{\circ}[/tex] and 4 [tex]a^{\circ}[/tex], they sum to 1080°)

[tex]4a + 480 = 1080[/tex]

[tex]4a = 600[/tex]

[tex]a = 150[/tex]

Hope this helps :)

Answer:

a = 150

Step-by-step explanation:

A octagon is 1080 degrees. The half circles are showing which angles are the same. So all the red circles are 120 degrees. To find the green circles, multiply 120 by 4 for the total of the four angles and then subtract it from 1080:

120(4) = 480

1080 - 480 = 600

So 600 is the total of all the green half circles added together, so divide 600 with 4 because there are four green half circles.

600/4 = 150

Answer:

There is 7.5% increase in the number of songs on his mp3 player.

Step-by-step explanation:

Original Songs in mp3= 440 songs

Final Songs in mp3= 473 songs

We need to find percent of increase in the number of songs on his mp3 player.

The formula used is: [tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100[/tex]

Now putting values and finding percent of increase

[tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%[/tex]

So, there is 7.5% increase in the number of songs on his mp3 player.

[tex]r = \frac{4}{3} (p - q) \\ [/tex]

Multiply sides by 3

[tex]3r = 4(p - q)[/tex]

Divide sides by 4

[tex] \frac{3r}{4} = p - q \\ [/tex]

Add sides q

[tex] \frac{3r}{4} + q = p \\ [/tex]

[tex]p = \frac{3}{4} r + q \\ [/tex]

Answer:

x = 8 base angle = 81 degrees

Step-by-step explanation:

Answer:

x = 8

base angle = 81 deg

Step-by-step explanation:

we observe that because the given triangle is a isosceles triangle, the base angles must be the same.

Hence the missing base angle must also be (10x+1)°

recall that all internal angles of an triangle must add up to 180 deg,

hence

180° = sum of all internal angles

180° = 18° + (10x+1)° + (10x+1)°

180° = 18° + 2(10x+1)°    (subtracting 18 from both sides)

180 - 18 = 2(10x+1)

162 = 2(10x+1)   dividing both sides by 2)

162 / 2 = 10x + 1

81 = 10x + 1    (subtracting 1 from both sides)

81 - 1 = 10x

10x = 80   (divide both sides by 10)

x = 80/10

x = 8   (answer)

substituting x = 8 into the expression for the base angle

base angle = (10x+1)

= 10(8) + 1

= 10 + 1

= 81

A,because it goes diagonally which (with the fraction) means that the fraction should be equal to the problem

Answer:

A

Step-by-step explanation:

I believe this is the right answer becasue all the other lines and curved (not constant) and the other goes in different directions.

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as [tex] y = mx [/tex].

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

[tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70 [/tex]

Substitute m = 70 into [tex] y = mx [/tex]

The equation would be:

[tex] y = 70x [/tex]

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.
