Answer:
Step-by-step explanation:
Edith is x years old.
Her sister,Madison is six years older than her. This means that the age of Madison is x + 6
Their mother is twice as old as Madison. This means that the age of their mother is expressed as
2(x + 6)
= 2x + 12
Their aunt, Elizabeth is x years older than their mother. This means that the expression that represents Elizabeth's age in years is
2x + 12 + x
= 3x + 12
It is
If you have a slope (which is before the x) then it’s a linear equation
Let A = { 0 , 2 , 4 , 6 } , B = { 1 , 2 , 3 , 4 , 5 } , and C = { 1 , 3 , 5 , 7 } . Find { x ∣ x ∈ B or x ∈ C } .

Answer:
Resultant is 50 mi/hr in the north east direction
Step-by-step explanation:
Plane is traveling north east at 150 mi/hr.
Now a wind is blowing from the south west at 100 mi/hr.
Now, north east and south west are directly opposite directions and such the angle between the resultant speed of the plane in flight and the wind will be;
150 - 100 = 50 mi/hr
Since the north east speed is greater than the south east speed, then the direction will be north east.
Thus, resultant is 50 mi/hr in the north east direction
