Answer:
x = 2.
Step-by-step explanation:
5[3(x + 4) − 2(1 − x)] − x − 15 = 14x + 55
5[3x + 12 - 2 + 2x] - x - 15 = 14x + 55
5[5x + 10] - x - 15 = 14x + 55
25x + 50 - x - 15 = 14x + 55 Now we subtract 14x from both sides:
25x + 50 - x - 15 - 14x = 14x - 14x + 55
10x + 50 - 15 = 55 Now we subtract 50, add 15 to both sides:
10x + 50 - 50 - 15 + 15 = 55 - 50 + 15
10x = 20
x = 2.

Answer:
9/2
Step-by-step explanation:
In order to find the slope of a line that is perpendicular to another line, you must find the opposite and reciprocal of that slope. So, you have 2/9, and then 9/2.
Answer:
option D
Step-by-step explanation:
we have a right triangle
we know
c^2=a^2+b^2
c=hypotenuse
c=52 cm
a=48 cm
b= 20 cm
we substitute in the equation c^2=a^a+b^2
so we have
52^2=48^2+20^2
52= sqrt(48^2+20^2)
52= sqrt(2304+400)
52= sqrt(2704)
52cm=52cm
so c=52 cm
so the option D is the correct answer
X is independent because none of the other numbers or variables affects it
