Answer:
14
Step-by-step explanation:
Answer: (D) 
Explanation:
Just a note on writing down these expressions: I recommend using parentheses whenever you can to avoid misinterpretation. An expression 1/x-1/y / 1/x+1/y could be interpreted by someone as 1/x-(1/y / 1/x)+1/y, which is a different thing.
Answer:
I just solved a question similar to this
Let's understand it
It's saying she got 660 or it is that her weekly pay is 660
So now let weekly pay which is P be 660
Hence the formulae is given
It's 480 + 18 (h – 30) = 660
Now its just boring calculation
If you mark it brainleist I will do the calculation for you wink wink
Never mind
480 + 18 (h – 30) = 660
18 (h – 30) = 660-480
18 (h – 30) = 120
(h – 30) = 120/18
(h – 30) = 6.6
h = 6.6+30
h= 36.6
So dam the Judy lady worked for 36.6 hours
Answer:
The correct answer is x < 2 or x > -2. The graph would be a line between -2 and 2 with an open circle on both.
Step-by-step explanation:
To solve, first solve the equation for the absolute value portion of the equation.
2|x| + 1 < 5
2|x| < 4
|x| < 2
Now since there is an absolute value around it, we have to complete it for the positive and negative versions.
x < 2 OR x > -2
