Answer:
-2/5
Step-by-step explanation:
2/5 + -4/5 becomes 2/5-4/5
2/5-4/5= -2/5
Answer:
Step-by-step explanation:
1. Create an equation
<em><u>Concept</u></em> :
If x = 5, then subtracting 5 from both sides gives you x - 5 = 0. Do this to both variables
If x - 5 = 0 and y - 12 = 0, those two statements equal the same thing. So
2. Add 5 to both sides to isolate variable X
3. (Optional) Plug given values into new equation to check answers
5 = 5 is a true statement
Answer:
b) The distance between −12 and −1 is ∣∣−12−(−1)∣∣
Step-by-step explanation:
The point A = -1
The point B = -12
To find The distance from A to B on the number line.
Now, distance of a point B from the point A is given as I B - A I
Definition of Modulus Function
I x I = x, if x > 0
= -x if x< 0
Similarly, here the distance is given as
I B - AI = I (-12) - (-1) I = I -12 + 1 I
= I -11 I = -(-11) = 11 ( as x < 0)
or the distance of point B from point A = + 11 units.
Hence, I B - AI = ∣∣−12−(−1)∣∣
