The integers are x, x + 2 and x + 4
x + x + 2 + x + 4 = 36
3x + 6 = 72
3x = 36 - 6 = 30
x = 30/3 = 10
The least numbers is 10
Therefore, the numbers are 10, 12 and 14
Q1
I like to use the standard form to write the equation of a perpendicular line, especially when the original equation is in that form. The perpendicular line will have the x- and y-coefficients swapped and one negated (remember this for Question 3). Thus, it will be
... 5x - 2y = 5(6) - 2(16) = -2
Solving for y (to get slope-intercept form), we find
... y = (5/2)x + 1 . . . . . matches selection C
Q2
The given equation has slope -3/6 = -1/2, so that will be the slope of the parallel line. (matches selection A)
Q3
See Q1 for an explanation. The appropriate choice is ...
... B. 4x - 3y = 5
Q4
The given line has slope -2, so you can eliminate all choices except ...
... D. -2x
Q5
The two lines have the same slope (3), but different intercepts, so they are ...
... A. parallel
The answer is 15.525. All you have to do is divide 279.45 by 18 which gives you 15.525.

Answer:
Step-by-step explanation:
58 is the answer without tax
so the cost of an adult ticket is 13 dollars
and the kids ticket is 8 dollars
use system of equations to solve this.
58=2x+4y
y=x-4
