y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of student tickets and y represent the number of adult tickets.

It is given by the equation:

  • x + y = 729    (1)
  • 3x + 5y = 2995   (2)

The solution to the equation is (325, 404) which is the point of intersection.

1.5( x + 4) -3 = 4.5 ( x - 2 )
Hitman42 [59]

Answer:

Step-by-step explanation:

1.5(x + 4) - 3 = 4.5(x - 2)

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

3 + 9 = 4.5x - 1.5x

12 = 3x

12/3 = x

You paint 1/2 wall in 1/4 hour. At that rate, how long will it take you to paint one wall?
Mnenie [13.5K]
(1/2) / (1/4) = 1 / x......1/2 wall to 1/4 hr = 1 whole wall to x hrs
cross multiply
(1/2)(x) = (1/4)(1)
1/2x = 1/4
x = 1/4 * 2
x = 2/4 reduces to 1/2....so it will take 1/2 hr (or 30 minutes) to paint the whole wall.

valkas [14]

Answer:

prime factors in ascending order of 1729 is 7 , 13 , 19

relation between  consecutive prime factors is 6

Step-by-step explanation:

given data

number = 1729

solution

we get here factors of 1729

1729 = 7 × 13 × 19

so that required prime factors in ascending order of 1729 is 7 , 13 , 19

and

now we get relation between these prime factors is the difference between consecutive prime factors is

13 - 7 =  6

19 - 13 = 6

so relation between  consecutive prime factors is 6
