Steps:
let “x” be number of hrs
let “y” be total cost
Abe:
50x + 75 = y
Plumbing Service:
65x=y
Since both equations are equal to y, you can set them equal to each other.
65x = 50x + 75
isolate for x:
65x - 50x = 75
15x = 75
x = 5
therefore it will take 5 hours for each to cost the same. you should call Abe for any task more than 5 hours because it will be cheaper and you should call the Plumbing Service for any task less than 5 hours because it will be cheaper.
The answer is B
Because if you use your calculation right you would end up with 16,463
In this instance the distance will be the hypotenuse of a right angle triangle.
x = 300/sin30 = 600
They are 600 ft away from each other
Answer:
-11 for the first one and 0 for the second one
Step-by-step explanation:
Answer: Hadassah is 12.
Explanation:
x=Hedya
y=Hannah
z=Hadassah
x+y+z=102
x=4y
y=1.5z
z=?
4x1.5z=6z (also x or Hedya's age)
z+1.5z+6z=102
8.5z=102
z=12
