6. The sum of three numbers A, B, and C, is $840. A is 2 times of B and C is half of B. Find the values of each number.​

Answer:

y = 10

Step-by-step explanation:

2y+30 = 3y+20

3y-2y= 30-20

y = 10

Answer:

[tex](2y30) = ( 3y + 20)[/tex]

so its 10 bc 30-20

Answer:

Part A: 3218 tickets

Part B: 6710 tickets

Step-by-step explanation:

Part A: 3,492 - 274 = 3,218

Part B: 3492 + 3218 = 6,710

Answer:

Part A: 3218

Part B: 6710

Step-by-step explanation:

For Part A, you need to subtract 274 from 3492.

3492-274 = 3218.

They sold 3218 tickets on the second night.

For Part B, you need to add the number of tickets they sold on opening night AND the second night.

3492+3218= 6710.

They sold 6710 tickets in total.

Answer:

1.$40

2.10

3.300

Step-by-step explanation:

1. 25-15=10

So that means she earns $5 per hour

5 pm - 2pm =3

5x3=15

25+15=40

2. 7-5=2

So that means he fixed 1 computer a hour

6pm - 3pm= 3

3x1=3

7+3=10

3.

9pm - 6pm =3

150/3=50

So that mean each hour the bus travels 50 miles

12pm - 9pm = 3

50x3=150

150+150=300

Step-by-step explanation:

I see only 2 statements :

15 > 9 that is true

and

|-9| > |15| that is NOT true

because

|-9| = 9

|15| = 15

and 9 is definitely not greater than 15.

Step-by-step explanation:

$5.25 savings on each ticket,

$73.50 savings on 14 tickets (5.25*14)

He paid $283.50

Original price of 14 tickets:

283.5+73.5

= 357

357/14

= $25.50 per ticket

Answer:

[tex]\LARGE\mathsf{y\:=\:-\frac{7}{10}x\:-\frac{21}{10} }[/tex]

Step-by-step explanation:

Given the two points, (-3, 0) and (7, -7):

We can use these points to solve for the slope, and determine the value of the y-intercept.

Let (x₁, y₁) = (-3, 0)

     (x₂, y₂) = (7, -7)

Substitute these values into the following slope formula:

[tex]\large\mathsf{m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}[/tex]

[tex]\large\mathsf{m = \frac {-7\: -\:0}{7\: -\:(-3)}\:=\:\frac{-7}{7\:+\:3}\:=\frac{-7}{10}}[/tex]

Therefore, the slope of the line is:  [tex]\large\mathsf{m\:=-\frac{7}{10}}[/tex].

Next, we must determine the value of the y-intercept. The y-intercept is the point on the graph where it crosses the y-axis. The coordinates of the y-intercept is often represented by (0, b ), where the y-coordinate, b, is used as the value of the y-intercept on the slope-intercept form.  

Using the slope,  [tex]\large\mathsf{m\:=-\frac{7}{10}}[/tex] , and one of the given points, (-3, 0), substitute these values into the slope-intercept form, y = mx + b, and solve for the value of b:

y = mx + b

[tex]\large\mathsf{0\:=-\frac{7}{10}(-3)\:+\:b}[/tex]

[tex]\large\mathsf{0\:=\frac{21}{10}+\:b}[/tex]

Subtract  [tex]\mathsf{\frac{21}{10}}[/tex] from both sides to isolate b :

[tex]\large\mathsf{0\:-\frac{21}{10}\:=\frac{21}{10}\:-\:\frac{21}{10}+\:b}[/tex]

[tex]\large\mathsf{\:-\frac{21}{10}\:=\:b}[/tex]

Therefore, the value of the y-intercept is: [tex]\large\mathsf{b\:=\:-\frac{21}{10}}[/tex].

The linear equation in slope-intercept form is:  [tex]\LARGE\mathsf{y\:=\:-\frac{7}{10}x\:-\frac{21}{10} }[/tex].  

Answer:

domain - -9 <x < 7

range - -6 < y < 4

Step-by-step explanation:

The speed of an athlete or a car or bicycle is given by the time it takes the athlete or car to complete a unit distance.

Reasons:

The time it takes athlete J to run 2/3 miles = 8 minutes

The time it takes athlete H to run [tex]2\frac{3}{4}[/tex] miles = [tex]\frac{1}{2}[/tex] hour

Required:

The time it would take athlete J to run one mile

Solution:

[tex]\displaystyle \frac{2}{3} \ mile \ takes \ runner \ J \ 8 \ minutes[/tex]

Therefore;

[tex]\displaystyle \frac{\frac{2}{3} \ mile}{\frac{2}{3} } \ takes \ runner \ J \ \frac{8 \ minutes}{\frac{2}{3} }[/tex]

[tex]\displaystyle \frac{\left(\frac{2}{3} \ mile \right)}{\left(\frac{2}{3} \right) } = 1 \ mile \ takes \ \frac{8 \ minutes}{\frac{2}{3} } = 8 \ minutes \times \frac{3}{2} = 12 \ minutes[/tex]

1 mile takes 12 minutes

It would take runner J 12 minutes to run 1 mile.

Answer:

They are perpendicular

Step-by-step explanation:

the first graph has 1/3 as its slope.

The inverse of 1/3 is the negative reciprocal, or -3/1, which is the same as -3.

Thus, as the second graph’s slope is -3, it is the inverse of the first graphs slope, which means the two graphs represent lines which are perpendicular to each other.

Answer: 434,524

Step-by-step explanation:

We know 36,500 is 8.4% of the total. To find 100%, we must divide 36500 by 8.4 to find 1% which is 4345.238...

To get from 1% to 100%, we must multiply our answer by 100 to get 434523.8 which we can then round to the nearest whole number 434524
